5ESS maintenance docs part ii
c3203f9134e0b1d6c43fd1a3b94f939e Any AM, SM, or CMP overload conditions are shown on the 109
display page. The SM and CMP overload information is provided on
a summary basis. If an SM overload occurs, the SM number and
type will be displayed in the indicator and backlighted. If more
than 16 SMs are in overload, a note will appear, partially
backlighted, indicating how many SMs are overloaded. For a
complete list of SMs in overload, the 900 command should be
entered. If a CMP overload occurs, the CMP number and whether
it is the primary (P) or mate (M) is shown.
Details on an SM overload can be obtained by entering the
DISPLAY SM X OVERLOAD INFO command shown on the display.
Likewise, details on an overloaded CMP can be obtained by
entering the DISPLAY PRIM CMP X OVERLOAD INFO or DISPLAY MATE
CMP X OVERLOAD INFO.
The REALTIME overload indicators will contain NONE, MINOR,
MAJOR, or CRIT to show the severity of the overload. NONE means
no overload exists. MINOR and MAJOR are different levels of
real-time overloads. CRIT (critical) is only used for SMs and is
the most severe type of overload.
The only craft action which can be taken during overload
conditions is to reduce or eliminate input messages/maintenance
commands. All other actions are initiated by the system.
For RESOURCE overloads, either NONE or the name of the resource
will be displayed. The monitored resources are as follows:
o MCB - Message Control Block
o PCB - Process Control Block
o RC/V - Tone Receivers (SM only)
o SCB - Stack Control Block
o TCB - Timer Control Block
o PKB - Packet Buffers [operator services position system
(OSPS) SMs only]
o PSU - Packet Switch Unit (Packet Switching SMs only)
o ADB - Analog Data Block (SM only)
o APB - Associated Process Block (SM only)
o BRCSDB - Business and Residence Custom Services (BRCS) Data
Block (SM only)
o CBDB - Call Buildup Data Block (SM only)
o CCBCOM - Channel Control Block (SM only)
o CHDB - Channel Data Block (SM only)
o CLDB - Calling Leg Data Block (SM only)
o DALB - D-Channel Application Linkage Block (SM only)
o DIB - Data Interface Block (SM only)
o DISPDB - Display Data Block (SM only)
o E911DB - Enhanced 911 Data Block (SM only)
o MDB - Model Data Block (SM only)
o MSG - Message Overflow (because of PIC overload)
o PHDB - Path Data Block (SM only)
o SCMDB - Shared Call Model Data Block (SM only)
o TSDB - Time Slot Data Block (SM only)
o PSIB - X-25 Packet Input Buffer (SM only)
o IAQ - CMP Input Queue (CMP only).
Essential Service Protection is normally inhibited. Therefore,
the INHIBITED text is not backlighted. When allowed, it gives
preferential treatment to designated lines (for example,
hospitals, police, fire departments, etc.) during periods of
overload.
If there is a network management control on, to prevent
overloads in this office, the ``SEE PAGE 130'' indicator will
show up and be backlighted.
An overload will cause the OVERLOAD indicator at the top of the
screen to backlight. The associated alarm level (CRITICAL,
MAJOR, or MINOR) will also backlight, if applicable.
The AM information box contains information regarding real-time
and resource overloads in the AM.
The information provided on Page 109 for the SMs is the SM
number and type. For additional information on a specific SM,
the poke 1300,X is used (where X is the number of the SM).
Figure .AW G285/ shows an example of the 109 display page with
specific AM overload information. It also shows up to 16 of the
SMs and up to 8 of the CMPs that are in overload. The note
EXCESSIVE is displayed and backlighted because there are greater
than 16 SMs in overload. The actual number of SMs in overload
(20) is displayed.
The SM overload information shows an overload for resource
E911DB, Enhanced 911 Data Block, a new resource for 5E7.
Similar to the SM, the CMP has limited information provided on
Page 109 as shown in Figure .AW G286/. The information shown is the
number of the CMP and whether the CMP is the primary or the
mate. For more specific information regarding a specific CMP,
pokes 1370,X for the primary CMP and 1371,X for the mate CMP
(where X is the number of the CMP) are used.
Commands are provided to inhibit and allow ESP, to output a list
of all SMs that are overloaded, and to obtain detailed
information on an SM overload condition.
In addition to these commands, any available paging command can
be entered from Display Page 109.

The 110 display page provides a list of system and AM inhibits
and provides maintenance menu commands for selected inhibits.
A SYSTEM inhibit applies to the AM and all SMs. An AM inhibit
applies only to the AM. Unless stated otherwise, all inhibit
requests are assumed to be phase-protected.
Each inhibit indicator on this display has three distinct
sections: the top line, the description, and the commands-
available line.
The top line in each box shows the box number. This line is
displayed in normal video and the field to the right of the box
number is blank unless an inhibit has been requested by the
craft. If an inhibit has been requested, INH, SET, MON, or CHG
is displayed to the right of the box number, as appropriate, and
the top line is backlighted. (For the remainder of the 110
display page description, the result of any of these operations
is referred to as an inhibit.) The presence of this text and
backlighting combination means the system has recorded the
inhibit request. It does not mean the inhibit is in effect.
Most of the inhibit/allow and set/clear commands are effective
immediately after the request. For these cases, all areas of the
indicator backlight together and one of the 3-character phrases
(INH, SET, MON, or CHG) will appear. However, in a few cases,
the status will change independent of the request. An example of
this is shown in box 21. The behavior of each indicator is
explained in the Indicators section on the next several pages.
The middle two lines of the indicator is the inhibit
description. These two lines show the name of the inhibit as
well as whether or not an inhibit is in effect. Inhibits can be
caused by system or craft-initiated actions. When an inhibit is
in effect, this section will be backlighted. In the SUMMARY
STATUS AREA, the SYS INH indicator will be backlighted.
The return of the top line to normal video means that a valid
request to allow (or clear) an inhibit has been accepted. A
valid allow request will also cause any text in the area to the
right of the box number to be blanked.
The last line of each indicator shows which menu commands, if
any, are available from the display. For example, at the bottom
of box 17 the numbers ``6 7 9'' appear. The ``6'' means this
item can be inhibited by entering 617, the ``7'' means it can
be allowed by entering 717, and the ``9'' designates output is
available with 917. On color MCCs, there is also color mapping
from the commands shown on the left of the display to the
numbers in the boxes. Boxes without commands listed are
inhibited only by the system or from manual action independent
of this display page.
Following is the correspondence between the number key and the
action taken:

9 Output
This paragraph describes the individual indicators and their
behavior.
Box 00 - Box 00 is not currently used.
Box 01 - Message Class Brevity Control
This indicator shows whether or not the automatic output message
class brevity control is inhibited. Brevity control is used to
restrict the generation of certain application output messages
for both the AM and equipped SMs. Inhibiting message class
brevity control permits normally suppressed messages to go to
the ROP or the log file.
The message class brevity control inhibit must be entered with
the teletypewriter (TTY) input message INH:BREVC,MSGCLS=a.
Since a named MSGCLS is required, a menu command is not
provided. Inhibiting brevity control for one or more MSGCLSs
may cause increased communication link traffic which can degrade
call processing performance and capacity. (See AT&T 235-600-700,
Input Messages Manual.) The request will display INH when
recorded. This inhibit will take effect immediately with the
request.
Entering allow command 701 generates the message
ALW:BREVC,MSGCLS=ALL. The request will clear the text INH when
recorded. This allow will take effect immediately with the
request.
This inhibit is cleared by any high-level AM initialization.
Box 02 - Message Class Log/Print Status
The box 02 indicates that at least one message class has the
log/print status that is different from the backup status.
To change the log/print status for one or all message classes,
enter input message CHG:LPS,MSGCLS={a|ALL} with additional
parameters. (See AT&T 235-600-700, Input Messages Manual.) The
request will display CHG when recorded. This change will take
effect immediately with the request.
Entering the menu command 902 generates the input message
OP:LPS,MSGCLS=ALL and causes the status of the message classes
to be printed at the ROP.
Box 03 - MDII Reporting
The machine-detected interoffice irregularity (MDII) indicator
is backlighted when one or more MDIIs are inhibited. The
inhibits are generated by the TTY input message INH:MDII with
additional parameters. When the inhibit is invoked, it
suppresses the printing of MDIIs for the trunk group(s)
specified by the input message. The request will display INH
when recorded. This inhibit will take effect immediately with
the request.
Entering the 903 command generates the message OP:MDII, which
causes a listing of all suppressed trunk MDIIs to be printed at
the ROP.
Box 04 - Manual Recent Change
This indicator shows whether or not manual entering of recent
changes is inhibited.
When the command 604 is entered, the message INH:RC is
generated. The request will display INH when recorded. This
inhibit will take effect immediately with the request.
The allow command 704 generates the message ALW:RC. The request
will clear the text INH when recorded.
Since the Automatic Customer Station Rearrangement (ACSR)
feature depends upon Recent Change, if Recent Change is
inhibited, ACSR is also inhibited. During manual inhibits of
Recent Change, the RC box (box 04) is illuminated and the CORC
box (box 05) is partially illuminated.
Box 05 - Customer-Originated Recent Change (CORC)
The box 05 indicator shows whether CORCs are inhibited.
Box 05 is shared by CORCs and the ACSR feature. Since the ACSR
feature depends upon Recent Change, if Recent Change is
inhibited, ACSR is also inhibited. During manual inhibits of
Recent Change, the RC box (box 04) is illuminated and the CORC
box (box 05) is partially illuminated.
When a 905 command is entered, ACSR queuing is inhibited and
CORCs are allowed.
Box 06 - Recent Change Logging
The box 06 indicator shows whether or not the logging of
manually entered recent changes for all processors is inhibited.
This does not include customer-originated recent changes. Recent
Change logging may be inhibited in the event logging is causing
a problem, thereby allowing recent changes to be entered.
Unlogged changes are lost after a boot.
Entering the command 606 generates the message INH:RCLOG. The
request will display INH when recorded. This inhibit will take
effect immediately with the request.
Entering the command 706 generates the message ALW:RCLOG. The
request will clear the text INH when recorded.
Box 07 - Box 7 is not currently used.
Box 08 - Communication Link Normalization
If a fault occurs in one or more SM communication links, the
system will automatically try to restore the link(s) on a
periodic basis. This inhibit will suppress this action when
active.
Entering command 608 will generate the message INH:CLNORM. The
request will display INH when recorded. This inhibit will take
effect immediately with the request.
When the command 708 is entered, it generates the message
ALW:CLNORM. The request will clear the text INH when recorded.
Since attempts to restore CLNKS are periodic, there may be a
delay from the time an allow or inhibit request is recorded
until the allow or inhibit is recognized.
Box 09 - Centralized Automatic Message Accounting (CAMA)
Suspension
The box 09 indicator shows whether or not calls are being routed
through the CAMA operator number identification (ONI) process
for billing. Since inhibiting this indicator causes lost
revenue, a minor alarm is sounded when the inhibit is invoked.
Entering the command 609 generates the message INH:CAMAONI. The
request will display INH when recorded. This inhibit will take
effect immediately with the request.
Entering the command 709 generates the message ALW:CAMAONI. The
request will clear the text INH when recorded.
Box 10 - Trunk Hold
The box 10 indicator shows whether or not one or more trunk
groups are being monitored.
To monitor one or more trunk groups, the input message MON:TRUNK
must be entered. The request will display MON when recorded.
This monitoring will take effect immediately with the request.
The system looks for stop-go signaling failures in members of
monitored group(s). If a failure occurs, the member is held
off-hook and out of service for the craft to determine the
nature of the failure.
The input message CLR:TRUNK is entered to remove the stop-go
signaling.
Warning: This message will return all members back to
service, even if they failed. The request will
clear the text MON when recorded.
Entering the 910 command generates the input message OP:TRUNK,
which causes a listing of all trunk groups and members being
monitored to be printed at the ROP.
Boxes 11 Through 15 - Boxes 11 through 15 are not currently
used.
Box 16 - Routine Audits
The box 16 indicator shows if the automatic routine execution of
one or both AM application audit cycles (OKP or SMKP) are
inhibited.
The only way to obtain a single audit inhibit is via a TTY input
message in the message mode. (See INH:AUD=a,ENV=b in AT&T 235-
600-700, Input Messages Manual.) Single inhibits are not phase
protected.
Entering the 616 command requests the inhibit of all audits and
generates the message INH:AUD=CYCLE,ENV. The request will
display INH when recorded. The request state does not
necessarily imply that the inhibit is in effect. Normally, the
status will follow the request within a short period of time.
If the 716 command is entered, the message ALW:AUD=CYCLE,ENV is
sent. The request will clear the text INH when recorded. The
request state does not necessarily imply that the inhibit has
been cleared. Normally, the status will follow the request
within a short period of time.
The command 916 (OP:AUD,STATUS=ALL,ENV=a) can be entered to get
the ROP listing of routine audit status for the application AM.
Box 17 - Routine Exercises
The box 17 indicator shows if any or all of the application
routine hardware exercises are inhibited in the communication
module (CM). Inhibits for routine exercises are effective for
only one exercise session. If the tests are in progress when the
message is received, the inhibit will not take place until the
next session.
Routine exercises are scheduled to run at specific times (for
example, daily at midnight). If inhibited exercises are allowed
after the scheduled time, the exercises are not started until
the next scheduled session.
When 617 is entered, the message INH:REX,CM is generated, which
inhibits all application CM routine exercises. The request will
display INH when recorded. This inhibit will take effect
immediately with the request.
If the command 717 is entered, the message ALW:REX,CM is
generated, which allows all application CM routine exercises.
The request will clear the text INH when recorded.
Entering the command 917 sends the message OP:REXINH,CM, which
generates a status listing at the ROP.
Note: These are application routine exercises and are
different from the routine exercises for the AM, as
shown on the EAI display.
Box 18 - Software Checks
The box 18 indicator reflects whether or not the AM application
software checks have been inhibited. The AM software checks and
the application software checks are different, but are
controlled together from manual commands.
The box 18 indicator can only be controlled from the EAI or TTY
input message INH:SFTCHK. This inhibit will prevent internal
software checks from causing initializations.
Entering the 618 command requests the inhibit of internal
software checks and generates the message INH:SFTCHK. The
request will display INH when recorded. The request state does
not necessarily imply that the inhibit is in effect. Normally
the status will follow the request within a short period of
time.
If the status is inhibited without being requested, the inhibit
was automatically applied by the system.
If the 718 command is entered, the message ALW:SFTCHK is sent.
The request will clear the text INH when recorded.
Box 19 - Min-Mode
The box 19 indicator shows the states of application min-mode.
When this box is backlighted, no call processing functions are
allowed in the AM. This is only used in extreme emergencies to
prevent customer actions from interfering with machine
operations.
Min-mode is invoked and deleted via EAI application pokes ``M''
and ``N,'' respectively.
The request will display INH when recorded. This inhibit will
take effect immediately with the request following the next
major AM initialization.
The request will clear the text INH when recorded and take
effect on the next major AM initialization.
Box 20 - Message Brevity Control
The box 20 indicator gives inhibit status of message brevity
control for all messages originating from the application
processes in the AM only.
Entering inhibit command 620 generates the message INH:BREVC,AM.
The request will display INH when recorded. This inhibit will
take effect immediately with the request.
Entering the allow command 720 generates ALW:BREVC,AM. The
request will clear the text INH when recorded.
This inhibit is cleared by any high-level AM initialization.
Box 21 - Recent Change Backout
The box 21 indicator shows whether or not uncommitted (recently
entered) AM recent changes are loaded or backed out. Backout can
only occur as a result of an AM high-level initialization.
The description portion shows when the recent changes are
actually backed out or loaded. If the backout is in progress, a
number will appear on the third line of the box showing the
progress of the backout. From 200 down to 100 is CORC backout;
200 meaning CORC is still fully backed out and 100 meaning CORC
is fully rolled forward. From 100 down to 0 is RC backout; 100
meaning RC is still fully backed out and 0 meaning RC is fully
rolled forward. Recent changes can be backed out only in
conjunction with a high-level initialization.
Recent changes should be backed out if a recent change is
suspected to be the cause of an AM performance problem.
When the command 421 is entered, the message SET:BACKOUT,RC,AM
is generated. The request will display SET when recorded. The
request state does not necessarily imply that the set is in
effect.
When the command 521 is entered, the message CLR:BACKOUT,RC,AM
is sent. The request will clear the text SET when recorded. The
request state does not imply that the backout has been cleared.
Box 22 - Emergency Action Interface/Miscellaneous Checks
The box 22 indicator shows if Emergency Action
Interface/Miscellaneous checks are inhibited. This box includes
hardware and error interrupts inhibits from the Emergency Action
Interface page and also error source inhibits.
When one of the messages INH:ERRINT or INH:ERRSRC is input, it
will cause the box to backlight. This box will also backlight
if error interrupt is inhibited on the Emergency Action
Interface page. Input messages ALW:ERRINT or ALW:ERRSRC will
allow the respective inhibits.
Note: The lower portion of this box is lighted only if
all error interrupt inhibits have been inhibited or
error source inhibits are inhibited. If error
interrupt checks are allowed unit by unit, the
indicator will not be cleared.
When the command 922 is entered, the message OP:ERRCHK is sent.
This generates a listing of the active inhibits.
Box 23 - Routine Maintenance
This indicator reflects whether or not a routine maintenance
function is inhibited. Should routine maintenance functions be
inhibited for an extended period of time, various system
resource availability and consistency may be adversely affected.
This indicator monitors the AM's Generated Key Collection and
Compression Routine inhibit status. If the routine is
inhibited, the description is backlighted.
When the 623 command is entered, the message INH:GKCCR,AM is
sent which requests that automatic executions of the Generated
Key Collection and Compression Routine be inhibited.
Entering command 723 generates the command ALW:GKCCR,AM which
requests that automatic periodic execution of the Generated Key
Collection and Compression Routine be allowed.
Box 24 - Hardware Checks
The box 24 indicator shows whether or not the AM/CM application
hardware checks have been inhibited. This indicator can only be
controlled from the EAI or by TTY input message INH:HDWCHK.
This inhibit will prevent maskable hardware faults from causing
recovery.
Entering the 624 command requests the inhibit of maskable
hardware faults and generates the message INH:HDWCHK. The
request will display INH when recorded. The request state does
not necessarily imply that the inhibit is in effect, since the
status will follow the request within a short period of time.
If the status is inhibited without being requested, the inhibit
was automatically applied to the system.
When the 724 command is entered, the message ALW:HDWCHK is sent.
The request will clear the text INH when recorded.
Boxes 25 Through 27 - Boxes 25 through 27 are not currently
used.
Figure .AW G287/ is an example of the 110 page display which shows one
system inhibit set and two AM inhibits set. Routine Exercises in
box 17 has been inhibited. Box 21 shows RC BACKOUT is currently
set and has been partially backed out (80%). However, the top
line is normal video and there is no SET text after the 21. This
indicates that the craft does not desire the recent changes to
be kept out.
In addition to the following commands, all available display
commands can be accessed from Display Page 110.

The purpose of the 115 display page is to provide a summary of
off-normal status for the hardware units and links which support
AM to SM(s) communication and provide paths for all circuit
switched calls.
The 115 display page has two separate and distinct versions.
The first version (Figure .AW G288/) is for offices with communication
module model 2 (CM2) hardware. The second version (Figure .AW G289/)
is for offices with CM1 hardware.
The 115 page provides overall status for MSGS 0, MSGS 1, MI/NC 0
(MI/LI/NC 0 for CM1), MI/NC 1 (MI/LI/NC 1 for CM1), TMS 0, TMS
1, communication links for the SMs, fan and fan fuse alarms for
the ONTCs (for the MSGSs and TMSs for CM1), the status of the
hardware check inhibit request bit, and the status of the
MI/NC/TMSs (MI/LI/NC/TMSs for CM1) functioning as a group
(ONTCCOM).
The ONTCCOM 0 includes MI 0 (and LI 0 in CM1), NC 0, and TMS 0.
The ONTC 0 includes ONTCCOM 0 and all DLIs on side 0. The
ONTCCOM 1 includes MI 1 (and LI 1 in CM1), NC 1, and TMS 1. The
ONTC 1 includes ONTCCOM 1 and all DLIs on side 1.
If an MSGS, MI/NC (MI/LI/NC in CM1), or TMSLNK has an off-normal
condition (out-of-service not family of equipment, unavailable,
hardware checks inhibited), the appropriate indicator with the
page number of the MCC page with the detailed information is
backlighted. The phrase ``SEE PAGE XXXX IF BACKLIT'' is
backlighted when any of the boxes are backlighted to point out
that the numbers in the boxes are the page numbers to request.
Note: The 1210 boxes are backlighted only for NC reference or
oscillator problems.
The CLNKS indicator is a summary of the equipped SM
communication links status which is detailed on Page 1260.
The CLNKs are not TMSLNKs. A CLNK is a communication path
between the AM and an SM which passes through an MSCU, MMP, TMS,
TMSLNK, and DLI. The TMSLNKs connect the TMS to the DLI.
The backlighted indicator shows the page necessary for acting on
the problem. As an example, the box with 1242 indicated is
backlighted in Figure .AW G288/ because a module message processor
(MMP) on Display Page 1242 is shown as out of service (OOS).
The MMP out of service is also reflected on the MSGS 0 Page
1240, but going to 1240 would not be the final step to see and
act on the problem so the MSGS 0 box with 1240 indicated is not
backlighted. If a foundation peripheral controller (FPC) or pump
peripheral controller (PPC) was out of service also, then the
MSGS 0 box would backlight as shown in Figure .AW G289/. The purpose
of this strategy is to get the craft directly to the problem
with minimum paging. Therefore, if the 1240 (MSGS 0) box and
the 1241 (or 1242) were both backlighted, an out of service (not
family of equipment), an unavailable, an out-of-service power,
or an unavailable power condition would exist in an MMP and an
FPC, PPC, or MSCU.
The TMS 0 and 1 boxes (indicating Page 1220) will never
backlight. If a TMS is OOS, it would be due to the whole ONTC
being OOS or UNV; therefore, 1209 is the appropriate page to
display.
Figure .AW G288/ shows an example of the CM2 Version with problems in
MI/NC 1, MSGS 0, TMS 0, CLNKS, and ONTC 1. Further information
on these problems would be found on display 1210 - MI/NC 0 & 1,
1242 - MSGS 0 - COMMUNITIES 2 - 7, 1221 - TMS 0 TMS LINKS 002 -
063, 1260 - CLNK SUMMARY, and 1209 - ONTC 0 & 1. There is a fan
alarm on ONTC 0, and the ONTC 1 fan fuse alarm is inhibited.
Figure .AW G289/ shows an example of the CM1 Version with problems in
MI/LI/NC 1, MSGS 0, TMS 0, CLNKS, and ONTC 0. Further
information on these problems would be found on displays 1210 -
MI/LI/NC 0 & 1, 1240 - MSGS 0 SUMMARY, 1221 - TMS 0 - TMS LINKS
002 - 063, 1260 - CLNK SUMMARY, and 1209 - ONTC 0 & 1. There is
a fan alarm on MSGS 0 and the TMS 0 fan fuse alarm is inhibited.
The FPC DPLF indicator is signaling that FPC duplex failure is
in effect.
There are no menu commands on the 115 display page. Commands for
removing, restoring, diagnosing, etc., are listed on the related
pages. There are no menu commands on the displays for fans or
fan fuses. For fans or fan fuses, see CLR:FANALM in AT&T 235-
600-700, Input Messages Manual.
All available display commands can be entered from the 115
display page.
The 116 display page provides status for various
units/activities which do not fall under any other grouping.
The External Sanity Monitor (ESM) has indicators for alarm,
inhibit, and power. If an alarm or an inhibit is present, the
appropriate indicator will backlight. If power is off, the POWER
indicator will backlight and the word OFF will be displayed.
The CALL MONITOR indicator shows whether the Call Monitor is
inhibited or allowed. Entering the command 601 generates the
message INH:CALLMON which will inhibit the monitor from making
test calls and performing call completion analysis. This also
clears the monitor's history data. The command 701 generates
the message ALW:CALLMON which allows the monitor to start the
cycle of making test calls and performing call completion
analysis. Command 801 generates the message RTR:CALLMON,ALARM
which retires the alarm indicator in the Call Monitor box.
Command 901 generates the message OP:CALLMON which generates the
OP CALLMON PAST 15 MINUTE REPORT on the ROP.
The indicators FRAME FUSE and FRAME FAN are for the
miscellaneous frame. If a fuse or fan alarm is present on the
miscellaneous frame, the corresponding indicator will backlight.
The fuse must be replaced to correct the frame fuse alarm. The
fan must be restored to operating condition to correct the frame
fan alarm. The input command CLR:FANALM,MFFAN can be entered to
clear the frame fan alarm after the alarm condition is fixed.
If a system inhibit is present, the word INH will be displayed
and backlighted to the right of the indicator label. The fuse
and fan alarms can only be inhibited by the system. An inhibit
means a scan point is chattering. The input command
ALW:ALM,MFFAN can be entered to allow the scan point after the
chattering problem is fixed.
The indicator GENERIC RETROFIT will backlight and change to
GENERIC RETROFIT ACTIVE when software release (generic) retrofit
is in progress.
The indicator ODD EVOL will backlight and change to ODD EVOL ACT
when ODD Evolution is in progress. ODD Evolution is initiated by
the command BKUP:ODD,ODDEVOL and stays in effect until the
actual software release cutover takes place.
The indicator OSPS EVOL will backlight and change to OSPS EVOL
ACT when OSPS Evolution is in progress. The OSPS Evolution is
initiated by the command BKUP:ODD,ODDEVOL if the office has an
OSPS configuration active. It stays in effect until the actual
software release cutover takes place.
The indicator ODD WARNING will backlight when either the amount
of ODD space being used has exceeded the engineering
recommendations for the AM or the automatic relation engineering
reorganization process has failed on one or more relations in
the AM. Entering the command 902 generates the input message
OP:ODDWARN,AM which will generate the OP ODDWARN output message
on the ROP.
The RC BACKUP indicator normally says NORMAL on the right part
of the indicator. If RC Backup fails in the AM, the text NORMAL
changes to FAILURE and the entire indicator backlights.
The MISCELLANEOUS ALARMS indicator has two subindicators: ALARM
and INHIBIT. These subindicators are backlighted for any alarm
and/or inhibit conditions present on the MISCELLANEOUS ALARMS
display. For additional information, enter command 119.
The next indicator, MTIB, will backlight if an off-normal
condition exists on the MTIB display. Enter command 127 for
further details.
In the CUTOVER indicator, the word ACTIVE will backlight if an
off-normal condition exists on the CUTOVER display (cutover
enabled, for example). Further information can be found on
display 197 - CUTOVER.
Any off-normal condition will cause the MISC indicator in the
SUMMARY STATUS AREA at the top of the screen to backlight.
Figure .AW G290/ is an example of the 116 display page which shows an
alarm and an inhibit present on 119 - MISCELLANEOUS ALARMS.
There is also something off-normal on Page 127 - MTIB STATUS.
These have caused the MISC status summary indicator at the top
of the screen to backlight.
Commands are provided to inhibit and allow the ESM and to clear
(retire) the exit pilot lamps. Commands are also provided to
inhibit and allow the call monitor, output the past 15-minute
interval history for the call monitor, and retire a call monitor
alarm.
Also, all available displays can be accessed from the 116
display page.

The purpose of the 117 page display is to provide a summary of
information associated with the application processor data links
(APDL).
The 113 page indicates that maintenance personnel can display
the 117 page, if desired.
The following items contain detailed information concerning each
field in the 117 page display:
o LINK: This field identifies the link by name (for example,
APDL01). The 01 attached to the APDL is the link number of
the link that is added to tuple relation RLCMAPDATA. The
link number is between 1 and 6 that corresponds to the
number assigned to that link via the RC/V view 24.1.
o PORT: This field indicates the data link connected to the
administrative module-input/output processor (AM-IOP).
o MODULE: This field indicates the data link is connected to
the AM-IOP.
o DEVICE: This field identifies the PC port and the hardware
status. The possible states are as follows: active (ACT),
out-of-service (OOS), initialization (INIT), or growth
(GROW). Also, the UCB of the SDL is indicated. For
example, in SDL 42 OOS, 42 is the UCB of the SDL.
o PC NAME: This field identifies the PC on which the port is
located. For application processor (AP) data links, there
is only one port per PC.
o SITE_ID: This field identifies the AP to which the link is
connected (also known as the AP). The SITE_ID number
matches the key field on RC/V view 24.1.
o SESSION: This field indicates the BX.25 session status
over a given link. The possible states are as follows:
connected (CONN), disconnected (DISC), or initialization
(INIT).
Figure .AW G291/ shows an example of the 117 page display.
Any of the available page displays can be accessed from the 117
page display.
CMD RESULT
121 Peripheral controller status is displayed -- IOP 0 & 1
122 Peripheral controller status is displayed -- IOP 2 & 3
The purpose of the 123 display page is to provide status and
maintenance commands for two DFCs and up to 16 moving head disks
(MHD). It also provides status and commands for disk
independent operation when both essential disks are lost. In
5E5 and later software releases, the 123 display page provides
status of the Auto MHD Configuration feature.
Prior to the 5E6 software release, the Storage Module Device
(SMD) was the only disk subsystem associated with the 5ESS(R)
switch. Effective with 5E6, the Small Computer Systems
Interface (SCSI) Bus Interface feature was introduced which can
either replace or coexist with the SMD. This means that a 5ESS
switch office with 5E6 can be only SMD, only SCSI, or both SMD
and SCSI.
If there are more than two DFCs in the system, a second DFSA
page (Page 125) is used. The format of the 125 page is the same
as the 123 except the AUTO MHD CONFIGURATION status is not
shown; it appears only on Page 123.
The 123 page has three separate and distinct functions.
The first function of this page is to provide status and
maintenance commands for DFCs 0 and 1 and associated MHDs (up to
16). If the system is equipped with SCSI, this page also
provides status and maintenance commands for SBUSes (up to 4).
The second function is to provide status and commands during
disk independent operation (DIOP). When both of the MHDs that
are marked E (essential) go out of service, this page is
automatically displayed. This is called full DIOP. The
appropriate menu commands to use under these circumstances are
the 600 series of commands. When in full DIOP (Figure .AW G293/), a
620 command will appear which will allow the MHD to be reloaded
from tape without bringing down call processing during the
reading of the tape. When the MHD has been reloaded, a minimum
of a 52 boot is required. The other 600 series commands, with
the exception of the 699 poke, may be used also when not in
DIOP. The 699 poke works only in full DIOP. In 5E7, both the
602 poke to restore the DFC controller and the 604 poke to
restore the SBUS controller require UCL when the system is in
full DIOP. These pokes (602/604) will not restore associated
subunits (MHDs) to prevent accidental disk restoral during disk
maintenance.
If only one of the essential MHDs goes out of service, the MHDs
are in simplex operation (Figure .AW G292/), but the page is not
automatically displayed.
During full DIOP, the area at the bottom of the page between the
two horizontal lines will display output messages for the 600
series menu commands.
The third function of the 123 page, in 5E5 and later software
releases, is to provide for the display of the Automatic MHD
Configuration feature. The AUTO MHD CONFIGURATION data
displayed on 123 page is a summary status of information from
Pages 178, Auto Spare Disk, and 179, Disk Configuration.
Possible values of the Automatic MHD Configuration feature are
as follows:
a. AUTO MHD CONFIGURATION READY: The feature is armed and
ready to run if needed.
b. SEE PAGE 179, CONFIG MHDs ...: The listed MHDs have been
reconfigured; see Page 179 for more data.
c. AUTO MHD CONFIGURATION OFF: The feature is turned off.
d. MHD CONFIG INHIBITED, SEE PAGE 178: The feature is blocked
on one or more MHDs or the entire office; see Page 178 for
more data.
e. MHD CONFIG IN PROGRESS, SEE PAGE 178: An MHD configuration
is in progress; see Page 178 for more data.
There are two columns of notations on the right side of each of
the MHD status columns. The first of the two columns contains
one of the following two letters:
o Y - (Yes): This means the MHD was diagnosed or restored
since the last system initialization and appears to be
usable.
o N - (No): This means the MHD was not diagnosed or restored
since the last system initialization and does not appear to
be usable.
The second column contains the letter E which signifies that the
associated MHD is essential.
The upper two display fields, OPTION LEVEL and CURRENT LEVEL,
inform the user of the optional disk independent operation
feature level selected for the operating system and the current
disk independent operation state the operating system is in.
The OPTION LEVEL displayed will be one of the following:
o NODIOP: Disk independent operation feature is not
selected.
o DIOP: Conditional disk independent operation is selected.
o UCLDIOP: Unconditional disk independent operation is
selected.
The CURRENT LEVEL displayed will be one of the following:
o NORMAL: Normal operating system without disk independent
operation mode.
o SIMPLEX: Operating system running with at least one
essential MHD out of service.
o DUPLEX: Operating system is running with all duplex
essential MHDs active.
o CONDITIONAL DIOP: Operating system is in conditional disk
independent operation mode with the last remaining duplex
essential MHD about to be removed from service.
o FULL DIOP: Operating system is running with a duplex
essential pair of MHDs out of service.
For each unit displayed, the following information is shown:
o Major state of the unit
o Minor state of the unit (if available)
o Usability of the unit (Y = usable, N = unusable)
o Essential status of the unit (E = essential, M = manually
nonremovable, blank = nonessential)
o Microcode status (Firmware of Pumpcode) for the DFC
o Overload status of a DFC.
Figure .AW G292/ shows the simplex version of the disk file system
access page for an office with SMD only. In this example, one
of the essential MHDs (MHD 1) is OOS, so the current level is
marked as SIMPLEX. The OOS MHD caused the AM PERPH indicator at
the top of the page to be backlighted. The automatic MHD
configuration feature is ready.
When the simplex mode is entered, the system begins to lock
essential, nonswappable processes from disk into core (AM
memory). Upon completion of the locking process, the system
will print the message, REPT DIOP SIMPLEX PROCESSING COMPLETED.
If the system has problems in locking the essential processes
into core, it will print the message, REPT DIOP SIMPLEX UNSWAP
FAILURE PID=xx (xx = utility ID of process that failed to lock
into memory). This message will reprint every 5 minutes until
the locking process is completed.
Figure .AW G293/ shows the FULL DIOP version.
Figure .AW G294/ shows the simplex version of the disk file system
access page for an office with SCSI only or with both SMD and
SCSI.
The only difference between the SCSI-DFSA and SMD-DFSA versions
of the 123 page is the addition of ``SBUS 0 SBUS 2'' under DFC
0, ``SBUS 1 SBUS 3'' under DFC 1 on the SCSI version, and the
604 command for RST/RMV SBUS.
Commands are provided to remove, restore, and diagnose the MHDs
and to take appropriate actions on the MHDs when one or more
essential MHDs are out of service.
All available displays can be accessed from the 123 page.

The purpose of the 125 display page is to provide status and
maintenance commands for two DFCs and up to 16 moving head disks
(MHD). It also provides status and commands for disk
independent operation when both essential disks are lost.
Prior to the 5E6 software release, the Storage Module Device
(SMD) was the only disk subsystem associated with the 5ESS
switch. Effective with 5E6, the SCSI Bus Interface Feature was
introduced which can either replace or coexist with the SMD.
This means that an office having the 5ESS switch with 5E6 can be
only SMD, only SCSI, or both SMD and SCSI.
This page exists only when there are more than two DFCs in the
system.
The format of the 125 page is the same as the 123 except the
AUTO MHD CONFIGURATION status is not shown; it appears only on
Page 123.
The 125 page has two separate and distinct functions.
The first function of this page is to provide status and
maintenance commands for DFCs 2 and 3 and associated MHDs (up to
16). If the system is equipped with SCSI, this page also
provides status and maintenance commands for SBUSes (up to 4).
The second function is to provide status and commands during
disk independent operation (DIOP). When in full DIOP, the 125
page will be accessible. The 620 poke (reload from tape option)
will only work on the 123 page. The other 600 series commands,
with the exception of the 699 poke, may be used also when not in
DIOP. The 699 poke works only in full DIOP. In 5E7, both the
602 poke to restore the DFC controller and the 604 poke to
restore the SBUS controller require UCL when the system is in
full DIOP. These pokes (602/604) will not restore associated
subunits (MHDs) to prevent accidental disk restoral during disk
maintenance.
If only one of the essential MHDs goes out of service, the MHDs
are in simplex operation (Figure .AW G295/), but the page is not
automatically displayed.
During full DIOP the area at the bottom of the page between the
two horizontal lines will display output messages for the 600
series menu commands.
There are two columns of notations on the right side of each of
the MHD status columns. The first of the two columns contains
one of the following two letters:
o Y (Yes): This means the MHD was diagnosed or restored
since the last system initialization and appears to be
usable.
o N (No): This means the MHD was not diagnosed or restored
since the last system initialization and does not appear to
be usable.
The second column contains the letter E which signifies that the
associated MHD is essential.
Figure .AW G295/ shows the simplex version of the disk file system
access page for an office with SMD only. In this example, one of
the essential MHDs (MHD 17) has gone out of service, so the
current level is marked as SIMPLEX. The OOS MHD caused the AM
PERPH indicator at the top of the page to be backlighted.
When the simplex mode is entered, the system begins to lock
essential, nonswappable processes from disk into core (AM
memory). Upon completion of the locking process, the system
will print the message, REPT DIOP SIMPLEX PROCESSING COMPLETED.
If the system has problems in locking the essential processes
into core, it will print the message, REPT DIOP SIMPLEX UNSWAP
FAILURE PID=xx (xx = utility ID of process that failed to lock
into memory). This message will reprint every 5 minutes until
the locking process is completed.
Figure .AW G296/ shows the simplex version of the disk file system
access page for an office with SCSI only or with both SMD and
SCSI.
The only difference between the SCSI-DFSA and SMD-DFSA versions
of the 125 page is the addition of ``SBUS 0 SBUS 2'' under DFC
2, ``SBUS 1 SBUS 3'' under DFC 3 on the SCSI version, and the
604 command to RST/RMV SBUS.
Commands are provided to remove, restore, and diagnose the MHDs
and to take appropriate actions on the MHDs when one or more
essential MHDs are out of service.
All available displays can be accessed from the 125 page.

The 130 display page provides status of the manual and automatic
NM system controls and status of NM circuit conditions. Also, it
provides a command to get a listing of any NM controls that are
YES.
When there is an overload in the system there are manual or
automatic controls that can be put on the system by Network
Management. The 130 page shows the status of these controls,
either YES or NO.
Any controls on this page that are YES will cause an indicator
that refers to this page to appear and be backlighted on Page
109 - OVERLOAD. In the STATUS SUMMARY AREA at the top of the
screen, the OVERLOAD status summary indicator will be
backlighted. This page also has a reference back to Page 109
that is displayed all the time.
Figure .AW G297/ shows there is a manual control on the CALL GAP and
transmit (XMT) of dynamic overload control (DOC) is allowed
(ALW).
The command on this page is provided to print a listing of any
NM controls that are YES. Also, any available paging commands
can be entered from this display.
CMD RESULT
900 Any YES NM controls are output (OP:NMPGE)
The purpose of the 141 through 144 display pages is to provide a
more detailed summary status of groups of 48 SMs on one display.
Displays 141, 142, 143, and 144 are very similar. Each one can
display summary status of up to 48 SMs. Page 141 displays status
for SMs 1 through 48, Page 142 displays summary status for SMs
49 through 96, Page 143 displays status for SMs 97 through 144,
and Page 144 displays summary status for SMs 145 through 192.
Each equipped SM has a unique indicator on these displays. Each
indicator has the following three distinct sections:
o SM NUMBER: There may be gaps in SM numbering for a
particular office. To provide flexibility in office
numbering schemes, the SM numbers are not necessarily
assigned sequentially. If an SM is not equipped, it is not
shown. An example of this is shown in the 141 page example
(Figure .AW G298/) by the blank indicators between SM 12 and SM
20, SM 20 and SM 24, etc.
o SM TYPE: There is a 3-character acronym to show how an SM
is being used. For example, an LSM is a local switching
module.
o SM STATUS PHRASE: This is a 10-character, maximum, phrase
which describes the most significant off-normal condition
in the SM. During initialization, the status phrase will
give the current initialization progress type. Table .AW TAK/
lists status phrases in order of priority and gives the
color and an explanation for each phrase. New phrases for
5E7 are E911 CRIT and ODD WARN. For detailed information
on SM progress markers, see AT&T 235-105-250, System
Recovery.
If more than one off-normal condition exists in an SM, a ``+''
will appear to the right of the status phrase (SMs 1, 5, and 48
in Figure .AW G298/). A complete list of active off-normal conditions
can be output via menu command 900.
In addition to this page, the status phrase is shown on all
per-SM pages.
When a new alarm condition on an SM occurs, the SM indicator
will begin flashing. The ALM RLS key will not stop the flashing.
The color of the flashing will reflect the new alarm only if the
newly recorded condition is of higher or equal priority to the
previous condition. To stop the flashing, the craft should
display the 1010 page for that SM. There is also a command to
retire the flashing for the range of SMs associated with the
page being displayed - 999. This is mainly provided for
situations such as during installation when SMs are being grown
and many SMs are displaying recurrent error conditions.
The backlighted note about the DLIs appears whenever an ONTC is
out of service or unavailable. The DLIs are under the
maintenance control of the ONTCs, thus all DLIs on a side are
affected when the ONTC of that side is off-normal.
For further details on any SM recovery-related activity or SM
inhibits, the craft would enter 1800,X to display the SM X
INHIBIT AND RECOVERY CONTROL page. This is the SMs control page
for emergency action.
For details on circuits out of service or hardware in a
particular SM, the craft would enter 1010,X to display the SM X
STATUS page. This page can be accessed during the initialization
of SM X or if SM X is isolated, but the only status that will
fill in are the SM STAT and RELATED PAGES boxes.
For details on ONTC circuits out of service, the craft would
enter 115 to display the COMMUNICATION MODULE SUMMARY page.
In the example of the 141 page shown in Figure .AW G298/, SM 1, which
is an LSM, has several off-normal conditions. The ``+''
indicates that there is more than one off-normal condition. For
the most critical condition, inhibits are set. Both SM 3 and 10
have circuits out of service. The SM 5, an RSM, has a hash
error plus other off-normal conditions. The SM 06, another LSM,
is isolated. This indicator would be flashing in the display,
which cannot be shown here. The SM 48, another RSM, has a
building power alarm plus other off-normal conditions. There is
an off-normal condition in ONTC 1 causing all the DLIs on Side 1
to be off-normal.
All available displays can be accessed from the 141 through 144
display pages.

The SM Page Index page provides an index to the SM and remote
switching module/remote integrated services line unit
(RSM/RISLU) pages.
The 1000 page is an index to the primary SM/RSM/RISLU pages that
directly have status reflected on the 1010 - SM X STATUS page.
No status is displayed on the 1000 page.
The page is divided into two parts. The first part displays all
the pages that are valid for local switching modules (LSM), host
switching modules (HSM), and RSMs/RISLUs. The second part
displays the pages that are only valid for RSMs/RISLUs and
remote sites.
Some pages shown on the 1000 page reference additional pages
that provide more detailed information. These additional pages
may not appear on the 1000 page.
Most SM pages are specified using an SM number. Some pages,
however, are referenced by the site number of a remote site.
For these pages (such as the 1600,SZ page), the ``S'' shown on
the 1000 page is actually entered as part of the menu command.
For example, entering ``1600,S3'' will display the status of
RSMs/HSMs at Site 3.
For all pages, once an SM page has been displayed for a

Note: The term basic rate interface (BRI) means the same
thing as digital subscriber line (DSL). This
document uses DSL, because the 1460 page display
does not identify BRI.
The 1460 page display provides summary status of the Operator
Services Position System (OSPS) data links on a per-SM basis.
The 1460 page display is not normally accessed when DSLs are IN
SERVICE. Usually the 1460 page is accessed because of the
following:
o DSL MAJOR or DSL MINOR alarm is indicated in the SM X
STATUS indicator box on the 1010-SM X LSM STATUS page
display.
o SEE 1460 is present in the RELATED PAGES box on the 1010-SM
X LSM STATUS page.
The 1460 page display provides the following information:
o Which data link types are equipped in an SM.
Note: If no ports are equipped for a specific data
link in the SM, then no data link block
appears on the 1460 page display.
o Which data link types have ports OOS and the relative
seriousness of the fault. Each data link type has an
associated indicator block. If a block is backlighted red,
a minor alarm is indicated; also, the term DSL_MINOR is
displayed in the SM XXX STATUS indicator block. If a block
is flashing from red to white, a major alarm is indicated;
also, the term DSL_MAJOR is displayed in the SM XXX STATUS
indicator block.
o Which page display gives more details (for example,
equipment numbers or states) concerning each data link type
equipped in an SM. On the 1460 page display (Figure .AW G300/),
one of the data links represented is DAS/C with the
associated page to see for more details (for example, SEE
147000). Where the first two zeros = the data link type
(service class) and the last zero indicates the screen
number of the specific service class.
Note: Figure .AW G261/ is an example of the XDB data link
page display (147072 - SM 017 LSM - XDB DATA
LINKS). This page identifies the global port
names, external names, and port status for the
data links of a specific type equipped on the
SM.
There are two types of data links (service classes) - simplex
and duplex. The following are simplex data links:
Note: The XDB data link is the only link that can be
equipped with more than 16 ports.
o HOBICV
o HOBIS
o HOBICR
o AQ
o XDB
o OAP.
The following are duplex data links:
o DAS/C
o RAS
o RTRS
o MISLNK.
The external information system (EIS) data link introduced in
5E6 is an N+K data link group, where N+K is defined in the
alarms section.
Major and Minor Alarms
For simplex data links, if more than 50 percent of the ports
associated to a specific data link (per-SM) are OOS (out of
service), a major alarm occurs.
For simplex data links, if one but no more than 50 percent of
the ports associated to the data link are OOS, a minor alarm
occurs.
Note: If exactly 50 percent of the ports associated to a
specific data link are OOS, a minor alarm occurs.
For the duplex DAS/C and RTRS data links, the DAS and RTRS data
links can be equipped with a maximum of two ports each. If only
one port is assigned to DAS/C or RTRS and the port is OOS, a
major alarm occurs. If two ports are assigned to DAS/C or RTRS
and one port is OOS, a minor alarm occurs; and if both ports are
OOS, a major alarm occurs.
For the duplex RAS data link, a maximum of eight RISLUs can be
equipped with RAS (that is, on a per-SM basis). Each RISLU site
can be assigned up to a maximum of two RAS data links,
therefore, providing a maximum of 16 data links per SM. A minor
alarm occurs when at least one RAS data link is OOS, but all of
the RISLU sites have at least one RAS link in service. A major
alarm occurs when at least one site has all RAS links OOS. Some
RISLU sites may only be equipped with one RAS link; when or if
this link is OOS, a major alarm occurs.
For the OAP data links, if one of the data links is OOS or
transitions from IS to IS/INIT, a major alarm occurs. Minor
alarms do not apply to the OAP.
EIS Alarm Strategy
The following terminology is used to define EIS data link alarm
strategy for an SM:
The set of EIS data links equipped on a specific SM and
connected to a specific EIS is referred to as an ``EIS Call
Processing Data link (CPDL) group.'' Each EIS CPDL group
consists of (N+K) data links, where N and K are specified
independently for each EIS CPDL group as follows:
1. N, indicating the minimum number of CPDLs that are needed
to support the message traffic during the busy hour for the
EIS CPDL group.
2. K, the number of CPDLs providing surplus traffic capacity
for the EIS CPDL group.
The EIS data link summary status for an SM is defined as
follows:
o DSL_NORMAL: All EIS data links on the SM are in service.
o DSL_MINOR: At least one EIS data link equipped on the SM
is out of service, but each EIS CPDL group has at least N
EIS data links in service.
o DSL_MAJOR: At least one EIS CPDL group has fewer than N
EIS data links in service.
Figure .AW G300/ shows an example of the 1460 page display.
Any available paging commands can be entered from this display.
The 171Y,X page display provides status and menu selection for
the maintenance actions of the ISLUMAN, ISLURG, and ISLUHLSC.
The last digit of the page number indicates the ISLU number (for
example, 1712). The ISLU numbers range from 1710 through 1717.
This page (one per ISLU) displays the status of each ISLUHLSC,
ISLUMAN, and ISLURG in both SGs 0 and 1. The possible states of
these indicators are ``ACT,'' ``CAMP,'' ``OOS,'' ``OOSFE,''
``DGR,'' ``GROW,'' and ``UNEQ.'' When any of the circuits in an
ISLU SG are in an off-normal state, the associated SG summary
status indicator for that SG is backlighted.
The 171Y,X page can be accessed from the 170Y - SM ISLU NETWORK
page display.
Figure .AW G301/ shows an example of the 171Y,X page display.
Commands are provided to remove, restore, and diagnose the
ISLUMAN, ISLUHLSC, and ISLURG of the SG. Also, the ISLU Line

The 1800,X page provides inhibit and recovery status and control
information for SM X. It functions like an emergency action
interface for the SM.
When an inhibit is requested, the top third of the associated
indicator will be backlighted to the INHIBIT state and the text
INH will appear in the corresponding box. When the inhibit is
actually activated, the rest of the associated indicator will be
backlighted to the INHIBIT state. On Page 114 - EQUIPPED SM
STATUS SUMMARY, the indicator for that SM will be backlighted;
and on the appropriate 141, 142, 143, or 144 page, the indicator
for that SM will be backlighted and the phrase INHIBITS will be
written, unless a more critical condition exists. In the SUMMARY
STATUS AREA, the SM critical indicator will be backlighted.
Some of the boxes on the 1800,X page have numbers at the bottom
of the box. These numbers show what commands are available from
the display. For example, at the bottom of Box 02 the numbers
``6 7 9'' appear. The ``6'' means this item can be inhibited by
entering 602, the ``7'' means it can be allowed by entering 702,
and the ``9'' means output is available with 902. On color MCC
terminals, there is also color mapping from the commands shown
on the left of the display to the numbers in the boxes.
In addition to the inhibit status indicators, there are
indicators for the status of the module controller time slot
interchangers (MCTSI) 0 and 1. When the MCTSIs are functioning
normally, the active MCTSI is marked active (ACT). If an MCTSI
is active forced, it is shown as ACTF and the other MCTSI is
marked unavailable (UNAV). The conditions standby and out of
service also apply to this display. During an initialization,
the status of the inactive MCTSI cannot be precisely determined
and the display will be blanked.
There is also an indicator for the state of the mate memory.
The possible states for the mate memory indicator are as
follows:
o STANDBY: Mate memory has been updated
o UPDATING: Mate memory update is in progress
o OOD: Mate memory is out of date
o PUMPED: Mate memory has been off-line pumped.
During an initialization, the status of the mate memory cannot
be precisely determined and the display will be blanked. The
lower area of the SM STAT indicator is for listing special
abnormal conditions in the SM. The possible conditions shown in
this area are as follows: GEN DIFF, ISOLATED, COMMLOST, SPEC
GROW, STNDALONE, INIT PEND, and HASH ERR.
This section describes the individual indicators and their
behavior.
Box 00 Routine Audits
This indicator shows if the automatic execution of the SM audit
cycle is inhibited.
Entering the 600 command generates the command
INH:AUD=CYCLE,SM=X and causes the top line of the indicator to
be backlighted and the text INH to be written. This request is
phase-protected. Single audits can also be inhibited via input
messages, but they are not phase-protected.
When the request is recorded, the description area of the box is
backlighted. This area is backlighted if one or more of the SM
audits are inhibited.
Entering the command 700 generates the command
ALW:AUD=CYCLE,SM=X and causes the indicator to return to normal
video.
The command 900 can be entered to get a ROP listing of routine
audit status for the SM. This command generates the message
OP:STATUS=ALL,AUD,SM=X.
Box 01 Auto Pump
When the 601 command is entered, it generates the command
INH:PUMP,SM=X. This inhibits the automatic pump of the SM on a
major initialization (except UNIX(R) RTR system level D4). This
inhibit is phase-protected.
The 701 command generates ALW:PUMP,SM=X. This command must be
entered to cancel the inhibit.
Box 02 Routine Exercises
This indicator shows if any or all of the routine exercises
(other than unit exercises) in the SM are inhibited.
Entering the command 602 generates the message INH:REX,SM=X.
Entering the command 702 generates the message ALW:REX,SM=X. To
print a status listing of routine exercises at the ROP, enter
the 902 command (OP:REXINH,SM=X).
Box 03 Manually Isolate
When the 403 command is entered, it generates the message
SET:ISOL,SM=X. This configures CLNK hardware to remove any level
2 protocol or active links from service. The removal is
unconditional, and the SM will remain isolated until the 503
command is entered which generates the message CLR:ISOL,SM=X.
Box 04 Software Checks
This indicator reflects whether or not the AM application
software checks are inhibited. If any software checks have been
inhibited, the description section is backlighted.
The command 604 generates the message INH:SFTCHK,SM=X and 704
generates ALW:SFTCHK,SM=X.
Box 05 Sanity Timer
This box provides commands to inhibit and allow the sanity
timer.
The command 605 generates the message ORD:CPI=X,CMD=INH and 705
generates ORD:CPI=X,CMD=ALW.
Box 06 Customer-Originated Recent Change (CORC) Logging
The command 606 generates the message INH:CORCLOG,SM=X which
causes the CORC logging to be inhibited.
Inhibiting customer-originated recent change logging should only
be used when recent change logging is suspected to be causing a
problem in the system.
The command 706 generates the message ALW:CORCLOG,SM=X.
Box 07 Recent Change Backout
This indicator shows the status of recent change (RC) backout.
If set, RCs will not be reentered following a high-level
initialization.
The description portion shows when the recent changes are
actually backed out or loaded. If the backout is in progress, a
number will appear on the third line of the box showing the
progress of the backout. From 200 down to 100 is CORC backout;
200 meaning CORC is still fully backed out and 100 meaning CORC
is fully rolled forward. From 100 down to 0 is RC backout; 100
meaning RC is still fully backed out and 0 meaning RC is fully
rolled forward. Recent changes can be backed out only in
conjunction with a high-level initialization.
The command 407 generates the message SET:BACKOUT,RC,SM=X and
507 generates CLR:BACKOUT,RC,SM=X.
Box 08 Hardware Checks
The command 608 (INH:HDWCHK,SM=X) causes all SM hardware checks
to be inhibited. Note: The lower portion of this box is lighted
only if all hardware checks have been inhibited.
If hardware checks are allowed circuit by circuit, the indicator
will not be cleared.
The command 708 (ALW:HDWCHK,SM=X) allows all SM hardware checks.
This will clear the backlighting of the box.
Box 09 SM Brevity Controls
Certain messages are normally suppressed from printing at the
ROP. By inhibiting the controls, all SM output messages would be
sent to the AM regardless of past message counts. Using this
command can increase link traffic to the AM, and thus, can be
service affecting.
Inhibiting the brevity controls is achieved by entering command
609 (INH:BREVC,SM=X). The controls can be returned to normal by
entering the command 709 (ALW:BREVC,SM=X).
Box 10 UPD Backout
This indicator shows whether or not recently applied SM program
updates are currently loaded or backed out.
The description portion shows when the program updates are
actually backed out or loaded. Program updates can be backed out
or loaded only in conjunction with a high-level initialization.
There are no menu commands for this box.
Box 11 Min Mode (Full Init)
This inhibit causes the SM to enter minimum mode and ignore all
call processing. This inhibit should only be used in extreme
emergencies, when all other normal recovery procedures have
failed.
When the 411 command is entered, the message SET:MINMODE,SM=X,FI
is sent. This initiates a high-level init and inhibits software
checks, hardware checks, routine exercises, and routine audits.
In addition, output message brevity control is allowed.
The only way to exit min mode is to enter the clear command or
message. The 511 command generates the message
CLR:MINMODE,SM=X,FI and causes a high-level init.
Box 12 Peripheral Fault Recovery Message Verbose
The command 412 (SET:PERPH,SM=X, VERBOSE) causes peripheral
fault recovery (PFR) to send to the AM peripheral error messages
that indicate that no recovery action has occurred in addition
to messages that indicate that a peripheral error has caused
recovery actions.
The command 512 (CLR:PERPH,SM=X, VERBOSE) causes PFR to suppress
the output of error reports. In the normal state, only output
messages which indicate that a peripheral error has caused
recovery actions on a circuit will be output.
The messages will be logged or printed, depending on the state
of the message class for each peripheral unit type.
Box 13 Alarmed Message Discard
This indicator shows if any output messages for this SM are
being discarded. Output messages of CRITICAL, MAJOR, MINOR, or
MANUAL can be discarded by the input message CHG:MSGCNTL. When
this input message is entered, the box will be backlighted.
Box 14 - Routine Maintenance
This indicator reflects whether or not a routine maintenance
function is inhibited. Should routine maintenance functions be
inhibited for an extended period of time, various system
resource availability and consistency may be adversely affected.
This box monitors the SM's Generated Key Collection and
Compression Routine inhibit status. If the routine is
inhibited, the description section is backlighted.
When the 614 command is entered, the message INH:GKCCR,SM=X is
sent which requests that automatic executions of the Generated
Key Collection and Compression Routine be inhibited.
Entering command 714 generates the command ALW:GKCCR,SM=X which
requests that automatic periodic execution of the Generated Key
Collection and Compression Routine be allowed.
Box 15 - Box 15 is currently not used.
Figure .AW G302/ is an example of the 1800,X page which shows the SM 1
sanity timer inhibited; MCTSI 0 is active and MCTSI 1 is in
standby. The mate memory is out of date and 50 percent of the
recent change has been backed out.
Any available paging command can be entered from the 1800,X
display page.
Input messages for commands shown in boxes on the display are
also described previously under the subheading, Indicators.

(INIT:SM=X,SI,PUMP)
922 Full Initialization is requested (INIT:SM=X,FI)
923 Full Initialization with pump is requested (INIT:SM=X,FI,PUMP)
924 Forces the reset counter to level 12 or greater (guaranteeing
a high level init). This poke does not require software sanity
in the SM. Poke 924 uses central processor intervention (CPI)
to force the SM to reset, and the ROM reset handler forces the
reset count to level 12 or greater. The remainder of the init
occurs normally (ORD:CPI=X,CMD=RESET).
Note: If the SM fails to respond to the FI PUMP and the
SM appears to have lost sanity, use MP RESET (924 poke). Also,
if the SM is attempting to pump and is failing, then MP RESET
may not help.
The 1850 page provides status displays for both the primary and
mate CMPs of the pair. Also provided are menu commands to
inhibit or allow hardware and software checks, routine audits,
automatic pump, brevity control, and set and clear for recent
change backout. Requests for high-level initialization can be
poked from the 1850 page.
On the 1850 page display, each processor is identified by its
CMP pair number and by its physical representation which
includes the message switch side. There will be only one
primary/mate CMP pair (0) for 5E6 and later.
During CMP initialization, the initialization status phrase
progress marks will be displayed in the PRIM STAT portion of the
screen along with the progress counter which shows the progress
within a particular phase of the initialization. The set of
progress marks used will be different from the set used for the
SMs pump and initialization sequences on MCC Page 1800,X.
Table .AW TAL/ shows the CMP Off-Normal Status Phrases along with the
priority, color, and an explanation of each.
After initialization has completed, the current (highest) level
CMP status will be displayed (just as with the SMs on the 1800,X
page). A ``+'' sign at the end of the status phrase indicates
that more than one off-normal status exists. The OP:SYSTAT
input message or 800 poke command can be used to obtain
additional off-normal status information. Also, the current
(highest) status of the MATE CMP will be displayed. Additional
status phrases are displayed in the other PRIM STAT and MATE
STAT boxes along with the peripheral control data (PCD) status.
Some of the boxes on the 1850 page have numbers at the bottom.
These numbers show what commands are available from the display.
For example, at the bottom of Box 00 the numbers ``6 7 9''
appear. The ``6'' means this item can be inhibited by entering
600, the ``7'' means it can be allowed by entering 700, and the
``9'' means output is available with 900. On color MCC
terminals, there is also color mapping from the commands shown
on the left of the display to the numbers in the boxes.
This section describes the individual indicators and their
behavior.
Box 00 - Routine Audits
This indicator shows if the automatic execution of the CMP audit
cycle is inhibited.
Entering the 600 command generates the command INH:AUD[=a],CMP=b
and causes the top line of the indicator to be backlighted and
the text INH to be written. This request is phase-protected.
Single audits can also be inhibited via input messages, but they
are not phase-protected.
When the request is recorded, the description area of the box is
backlighted. This area is backlighted if one or more of the CMP
audits are inhibited.
Entering the command 700 generates the command ALW:AUD[=a],CMP=b
and causes the indicator to return to normal video.
The command 900 can be entered to get a ROP listing of routine
audit status for the CMP. This command generates the message
OP:STATUS[=a],AUD[=b],CMP=c.
Box 01 - Auto Pump
When the 601 command is entered, it generates the command
INH:PUMP,CMP=a. This inhibits the automatic pump of the CMP on a
major initialization (except UNIX RTR system level D4). This
inhibit is phase-protected.
The 701 command generates ALW:PUMP,CMP=a. This command must be
entered to cancel the inhibit.
Box 02 - Routine Maintenance
This indicator reflects whether or not a routine maintenance
function is inhibited. Should routine maintenance functions be
inhibited for an extended period of time, various system
resource availability and consistency may be adversely affected.
This box monitors the CMP's Generated Key Collection and
Compression Routine inhibit status. If the routine is
inhibited, the description section is backlighted.
When the 602 command is entered, the message INH:GKCCR,CMP=a is
sent which requests that automatic executions of the Generated
Key Collection and Compression Routine be inhibited.
Entering command 702 generates the command ALW:GKCCR,CMP=a which
requests that automatic periodic execution of the Generated Key
Collection and Compression Routine be allowed.
Box 04 - Software Checks
This indicator reflects whether or not the AM application
software checks are inhibited. If any software checks have been
inhibited, the description section is backlighted.
The command 604 generates the message INH:SFTCHK,CMP=a and 704
generates ALW:SFTCHK,CMP=a.
Box 05 - Alarmed Messages Discarded
The input message CHG:MSGCNTL,CMP=a (where a is the CMP pair
number) is associated with box 05. This box will also backlight
to indicate some type of alarmed messages (CRITICAL, MAJOR,
MINOR, or MANUAL) are being discarded.
Box 06 - Box 06 is currently not used.
Box 07 - Recent Change Backout
This indicator shows the status of RC backout. If set, RCs will
not be reapplied following a full initialization.
The description portion shows when the recent changes are
actually backed out or applied. A number indicating the status
of a backout in progress will appear on the third line of the
box. From 200 down to 100 is CORC backout; 200 meaning CORC is
still fully backed out and 100 meaning CORC is fully rolled
forward. From 100 down to 0 is RC backout; 100 meaning RC is
still fully backed out and 0 meaning RC is fully rolled forward.
Recent changes can be backed out only in conjunction with a full
initialization.
The command 407 generates the message SET:BACKOUT,RC,CMP=a and
507 generates CLR:BACKOUT,RC,CMP=a.
Box 08 - Hardware Checks
The command 208 (INH:HDWCHK,CMP=a) causes all CMP hardware
checks to be inhibited. The lower portion of this box is
lighted only if all hardware checks have been inhibited.
If hardware checks are allowed circuit by circuit, the indicator
will not be cleared.
The command 308 (ALW:HDWCHK,CMP=a) allows all CMP hardware
checks. This will clear the backlighting of the box.
Box 09 - CMP Brevity Controls
Certain messages are normally suppressed from printing at the
ROP. By inhibiting the controls, all CMP output messages would
be sent to the AM regardless of past message counts. Using this
command can increase link traffic to the AM, and thus, can be
service affecting.
Inhibiting the brevity controls is achieved by entering command
609 (INH:BREVC,CMP=a). The controls can be returned to normal
by entering the command 709 (ALW:BREVC,CMP=a).
Box 10 - UPD Backout
This indicator shows whether or not recently applied CMP program
updates are currently applied or backed out.
The description portion shows when the program updates are
actually backed out or applied. Program updates can be backed
out or applied only in conjunction with a full initialization.
There are no menu commands for this box.
Box 11 - Min Mode
This box is used to display whether or not the AM/CMPs are in
minimum mode.
The CMP 0 PRIM STAT box located in the top-middle portion of the
screen can be updated with vartext for internal indicators.
This box contains the following three subboxes:
1. Top PRIM STAT box: Left half is logical link map
designation (0-0 or 1-0) and right half is PCD status.
2. Middle PRIM STAT box: Contains the following three lines
of information:
o Initialization phrases and highest priority status
phrases for PRIM CMP
o Initialization progress counter
o Initialization phrase trigger.
3. Bottom PRIM STAT box: Contains the following four lines:
o HASH ERR
o GEN DIFF
o SPEC GROW (Not Used)
o COMM LOST.
The MATE STAT box, located in the lower middle portion of the
screen, contains the following two subboxes:
1. Top MATE STAT box: The left half contains the logical link
map designation (0-0 or 1-0) for the MATE CMP. The right
half displays the PCD status of the MATE CMP.
2. Bottom MATE STAT box: Contains initialization and status
phrases for the MATE CMP.
Figure .AW G303/ shows an example of the 1850 display page.
Any available paging command can be entered from the 1850
display page.
All 600 and 700 level pokes are duplex commands which can only
be entered from the primary (PRIM) CMP page (1850).

The 1851 page is similar to the 1850 except that 600 and 700
level pokes cannot be entered from the 1851 page. Also, the
1851 page has the 930 and 931 commands that the 1850 does not
have.
The 1851 page provides status displays for both the primary and
mate CMP pair. Also provided are menu commands to inhibit or
allow hardware and software checks, routine audits, automatic
pump, brevity control, and set and clear for recent change
backout. Requests for full initialization can be poked from the
1851 page.
On the 1851 page display, each processor is identified by its
CMP pair number and by its physical representation which
includes the message switch side. There will be only one
primary/mate CMP pair (0) for 5E6 and later.
During CMP initialization, the initialization status phrase
progress marks will be displayed in the PRIM STAT portion of the
screen along with the progress counter which shows the progress
within a particular phase of the initialization. The set of
progress marks used will be different from the set used for the
SMs pump and initialization sequences on MCC Page 1800,X.
Table .AW TAM/ shows the CMP Off-Normal Status Phrases along with the
priority, color, and an explanation of each.
After initialization has completed, the current (highest) level
CMP status will be displayed (just as with the SMs on the 1800,X
page). A ``+'' sign at the end of the status phrase indicates
that more than one off-normal status exists. The OP:SYSTAT
input message or 800 poke command can be used to obtain
additional off-normal status information. Also, the current
(highest) status of the primary CMP will be displayed.
Additional status phrases are displayed in the other PRIM STAT
and MATE STAT boxes along with the PCD status.
Some of the boxes on the 1851 page have numbers at the bottom.
These numbers show what commands are available from the display.
For example, at the bottom of Box 00 the number ``9'' appears.
The ``9'' means output is available by entering 900. On color
MCC terminals, there is also color mapping from the commands
shown on the left of the display to the numbers in the boxes.
This section describes the individual indicators and their
behavior.
Box 00 - Routine Audits
This indicator shows if the automatic execution of the CMP audit
cycle is inhibited.
The command 900 can be entered to get a ROP listing of routine
audit status for the CMP. This command generates the message
OP:STATUS[=a],AUD[=b],CMP=c.
Box 01 - Auto Pump
Commands to allow or inhibit automatic pump of the CMP must be
entered from Page 1850.
Box 02 - Routine Maintenance
This indicator reflects whether or not a routine maintenance
function is inhibited. Should routine maintenance functions be
inhibited for an extended period of time, various system
resource availability and consistency may be adversely affected.
This box monitors the CMP's Generated Key Collection and
Compression Routine inhibit status. If the routine is
inhibited, the description section is backlighted.
Commands to allow or inhibit routine maintenance functions of
the CMP must be entered from Page 1850.
Box 03 - Box 03 currently is not used.
Box 04 - Software Checks
Commands to allow or inhibit software checks of the CMP must be
entered from Page 1850.
Box 05 - Alarmed Messages Discarded
The input message CHG:MSGCNTL,CMP=a (where a is the CMP pair
number) is associated with box 05. This box will also backlight
to indicate some type of alarmed messages (CRITICAL, MAJOR,
MINOR, or MANUAL) are being discarded.
Box 06 - Box 06 is currently not used.
Box 07 - Recent Change Backout
This indicator shows the status of RC backout. If set, RCs will
not be reapplied following a full initialization.
The description portion shows when the recent changes are
actually backed out or applied. If the backout is in progress,
a number will appear on the third line of the box showing the
progress of the backout. From 200 down to 100 is CORC backout;
200 meaning CORC is still fully backed out and 100 meaning CORC
is fully rolled forward. From 100 down to 0 is RC backout; 100
meaning RC is still fully backed out and 0 meaning RC is fully
rolled forward. The RCs can be backed out only in conjunction
with a full initialization.
The command 407 generates the message SET:BACKOUT,RC,CMP=a and
507 generates CLR:BACKOUT,RC,CMP=a.
Box 08 - Hardware Checks
The command 208 (INH:HDWCHK,CMP=a) causes all CMP hardware
checks to be inhibited.
Note: The lower portion of this box is lighted only if
all hardware checks have been inhibited.
If hardware checks are allowed circuit by circuit, the indicator
will not be cleared.
The command 308 (ALW:HDWCHK,CMP=a) allows all CMP hardware
checks. This will clear the backlighting of the box.
Box 09 - CMP Brevity Controls
Commands to allow or inhibit brevity control must be entered
from Page 1850.
Box 10 - UPD Backout
This indicator shows whether or not recently applied CMP program
updates are currently applied or backed out.
The description portion shows when the program updates are
actually backed out or applied. Program updates can be backed
out or applied only in conjunction with a full initialization.
There are no menu commands for this box.
Box 11 - Min Mode
This box is used to display whether or not the AM/CMPs are in
minimum mode.
The MATE STAT box located in the top-middle portion of the
screen can be updated with vartext for internal indicators.
This box contains the following three subboxes:
1. Top MATE STAT box: Left half is logical link map
designation (0-0 or 1-0) and right half is PCD status.
2. Middle MATE STAT box: Contains the following three lines
of information:
o Initialization phrases and highest priority status
phrases for MATE CMP
o Initialization progress counter
o Initialization phrase trigger.
3. Bottom MATE STAT box: Contains the following five lines:
o HASH ERR
o GEN DIFF
o SPEC GROW (Not Used)
o COMM LOST
o INIT PEND.
The PRIM STAT box, located in the lower middle portion of the
screen, contains the following two subboxes:
1. Top PRIM STAT box: The left half contains the logical link
map designation (0-0 or 1-0) for the PRIM CMP. The right
half displays the PCD status of the PRIM CMP.
2. Bottom PRIM STAT box: Contains initialization and status
phrases for the PRIM CMP.
Figure .AW G304/ shows an example of the 1851 display page.
Any available paging command can be entered from the 1851
display page.

This subsection contains descriptions and examples of the master
control center (MCC) page displays that were added with or
changed with the 5E8 software release.
Refer to Table .AW TAF/ for a complete listing of MCC page displays.
The 107 display page provides a listing of trunk groups that
have reached or exceeded their automatic maintenance limit
(AML). The AML for each trunk group is set through Recent
Change View 5.1.
Two counts are maintained by the 5ESS(R) switch for each trunk
group in an office. These counts are as follows:
o TG OOS: Total number of out-of-service (OOS) members
(individual trunks)
o AML OOS: Total number of OOS members (individual trunks)
having OOS status due to AML reasons.
If a trunk group's AML OOS count has reached its automatic
maintenance limit, its TG OOS count has also reached its
automatic maintenance limit, but not vice versa.
When a trunk group's AML is reached or exceeded by either count,
the trunk group number will be shown on the display. In the
SUMMARY STATUS AREA, the CKT LIM indicator will be backlighted
and flashing. The associated alarm level (CRITICAL, MAJOR, or
MINOR) will also be backlighted, as applicable.
The 107 page display lists in numerical order the number(s) of
the first 40 trunk groups that have reached or exceeded their
AML. When more than 40 trunk groups have reached or exceeded
their AML, the word ``EXCESSIVE'' will be backlighted at the
bottom of the listing. No trunk group numbers are shown on the
page display if all trunk groups are normal.
Note: A trunk group with its AML set to 0 will not be
included on the page display until this limit is
actually exceeded (that is, at least one member has
to be OOS for a trunk group to be included on the
display).
Figure .AW G305/ is an example of the 107 display page. In this
example, an excessive amount of trunk groups (more than 40) are
OOS as reflected by the backlighted indicator ``EXCESSIVE''. A
MAJOR alarm condition is shown.
Commands are provided to output listings of all trunk groups
whose AML OOS count has reached or exceeded their respective
AMLs and all trunk groups having an OOS member(s).
All available paging commands can be entered from this display.
CMD RESULT
900 Listing of trunk groups whose AML OOS count has reached or
exceeded their respective AMLs is printed at the ROP
(OP:AML[,TG=a])
where ``a'' is a specific trunk group number.
901 Listing of trunk groups having any OOS member(s) is printed at
the ROP (OP:TGCNT[,TG=a]) where ``a'' is a specific trunk
group number.
The 109 display page provides an indication of resource or
real-time overloads in the administrative module (AM),
communication module processor (CMP), and SM(s) and commands to
inhibit or allow essential service protection (ESP).
Any AM, SM, or CMP overload conditions are shown on the 109
display page. The SM and CMP overload information is provided on
a summary basis. If an SM overload occurs, the SM number and
type will be displayed in the indicator and backlighted. If more
than 16 SMs are in overload, a note will appear, partially
backlighted, indicating how many SMs are overloaded. For a
complete list of SMs in overload, the 900 command should be
entered. If a CMP overload occurs, the CMP number and whether
it is the primary (P) or mate (M) are shown.
Details on an SM overload can be obtained by entering the
DISPLAY SM X OVERLOAD INFO command shown on the display.
Likewise, details on an overloaded CMP can be obtained by
entering the DISPLAY PRIM CMP X OVERLOAD INFO or DISPLAY MATE
CMP X OVERLOAD INFO.
The REALTIME overload indicators will contain NONE, MINOR,
MAJOR, or CRIT to show the severity of the overload. NONE means
no overload exists. MINOR and MAJOR are different levels of
real-time overloads. CRIT (critical) is only used for SMs and is
the most severe type of overload.
The only craft action which can be taken during overload
conditions is to reduce or eliminate input messages/maintenance
commands. All other actions are initiated by the system.
For RESOURCE overloads, either NONE or the name of the resource
will be displayed. The monitored resources are as follows:
o MCB - Message Control Block
o PCB - Process Control Block
o RCV - Tone Receivers (SM only)
o SCB - Stack Control Block
o TCB - Timer Control Block
o PKB - Packet Buffers [operator services position system
(OSPS) SMs only]
o PSU - Packet Switch Unit (Packet Switching SMs only)
o ADB - Analog Data Block (SM only)
o APB - Associated Process Block (SM only)
o BRCSDB - Business and Residence Custom Services (BRCS) Data
Block (SM only)
o CBDB - Call Buildup Data Block (SM only)
o CCBCOM - Channel Control Block Communication Region (SM
only)
o CHDB - Channel Data Block (SM only)
o CLDB - Calling Leg Data Block (SM only)
o DALB - D-Channel Application Linkage Block (SM only)
o DIB - DSL Input Buffer (SM only)
o EDIB - Extended DSL Input Buffer (SM only)
o DISPDB - Display Data Block (SM only)
o E911DB - Enhanced 911 Data Block (SM only)
o MDB - Model Data Block (SM only)
o MSG - Message Overflow (because of PIC overload)
o PHDB - Path Data Block (SM only)
o SCMDB - Shared Call Model Data Block (SM only)
o TSDB - Time Slot Data Block (SM only)
o PSIB - X-25 Packet Switch Input Buffer (SM only)
o IAQ - CMP Input Queue (CMP only).
Essential Service Protection is normally inhibited. Therefore,
the INHIBITED text is not backlighted. When allowed, it gives
preferential treatment to designated lines (for example,
hospitals, police, fire departments, etc.) during periods of
overload.
If the network management control is on to prevent overloads in
this office, the ``SEE PAGE 130'' indicator will appear and be
backlighted.
An overload will cause the OVERLOAD indicator at the top of the
screen to backlight. The associated alarm level (CRITICAL,
MAJOR, or MINOR) will also backlight, if applicable.
The AM information box contains information regarding real-time
and resource overloads in the AM.
The information provided on Page 109 for the SMs is the SM
number and type. For additional information on a specific SM,
the poke 1300,X is used (where X is the number of the SM).
Figure .AW G306/ shows an example of the 109 display page with
specific AM overload information. It also shows up to 16 of the
SMs and up to 8 of the CMPs that are in overload. The note
EXCESSIVE is displayed and backlighted because there are greater
than 16 SMs in overload. The actual number of SMs in overload
(20) is displayed.
The SM overload information shows an overload for resource
Extended DSL Input Buffer (EDIB), a new resource for 5E8.
Similar to the SM, the CMP has limited information provided on
Page 109 as shown in Figure .AW G307/. The information shown is the
number of the CMP and whether the CMP is the primary or the
mate. For more specific information regarding a specific CMP,
pokes 1370,X for the primary CMP and 1371,X for the mate CMP
(where X is the number of the CMP) are used.
Commands are provided to inhibit and allow ESP, to output a list
of all SMs that are overloaded, and to obtain detailed
information on an SM overload condition.
In addition to these commands, any available paging command can
be entered from Display Page 109.

The 110 display page provides a list of system and AM inhibits
and provides maintenance menu commands for selected inhibits.
A SYSTEM inhibit applies to the AM and all SMs. An AM inhibit
applies only to the AM. Unless stated otherwise, all inhibit
requests are assumed to be phase-protected.
Each inhibit indicator on this display has three distinct
sections: the top line, the description, and the commands-
available line.
The top line in each box shows the box number. This line is
displayed in normal video, and the field to the right of the box
number is blank unless an inhibit has been requested by the
craft. If an inhibit has been requested, INH, SET, MON, or CHG
is displayed to the right of the box number, as appropriate, and
the top line is backlighted. (For the remainder of the 110
display page description, the result of any of these operations
is referred to as an inhibit.) The presence of this text and
backlighting combination means the system has recorded the
inhibit request. It does not mean the inhibit is in effect.
Most of the inhibit/allow and set/clear commands are effective
immediately after the request. For these cases, all areas of the
indicator backlight together and one of the 3-character phrases
(INH, SET, MON, or CHG) will appear. However, in a few cases,
the status will change independent of the request. An example of
this is shown in box 21. The behavior of each indicator is
explained in the Indicators section on the next several
paragraphs.
The middle two lines of the indicator is the inhibit
description. These two lines show the name of the inhibit as
well as whether or not an inhibit is in effect. Inhibits can be
caused by system or craft-initiated actions. When an inhibit is
in effect, this section will be backlighted. In the SUMMARY
STATUS AREA, the SYS INH indicator will be backlighted.
The return of the top line to normal video means that a valid
request to allow (or clear) an inhibit has been accepted. A
valid allow request will also cause any text in the area to the
right of the box number to be blanked.
The last line of each indicator shows which menu commands, if
any, are available from the display. For example, at the bottom
of box 17 the numbers ``6 7 9'' appear. The ``6'' means this
item can be inhibited by entering 617, the ``7'' means it can
be allowed by entering 717, and the ``9'' designates output is
available with 917. On color MCCs, there is also color mapping
from the commands shown on the left of the display to the
numbers in the boxes. Boxes without commands listed are
inhibited only by the system or from manual action independent
of this display page.
Following is the correspondence between the number key and the
action taken:
Number Action
4 Set
5 Clear
6 Inhibit
7 Allow
9 Output
This paragraph describes the individual indicators and their
behavior.
Box 00 - Box 00 is not currently used.
Box 01 - Message Class Brevity Control
This indicator shows whether or not the automatic output message
class brevity control is inhibited. Brevity control is used to
restrict the generation of certain application output messages
for both the AM and equipped SMs. Inhibiting message class
brevity control permits normally suppressed messages to go to
the ROP or the log file.
The message class brevity control inhibit must be entered with
the teletypewriter (TTY) input message INH:BREVC,MSGCLS=a.
Since a named MSGCLS is required, a menu command is not
provided. Inhibiting brevity control for one or more MSGCLSs
may cause increased communication link traffic which can degrade
call processing performance and capacity. (See AT&T 235-6s00-
700, Input Messages Manual.) The request will display INH when
recorded. This inhibit will take effect immediately with the
request.
Entering allow command 701 generates the message
ALW:BREVC,MSGCLS=ALL. The request will clear the text INH when
recorded. This allow will take effect immediately with the
request.
This inhibit is cleared by any high-level AM initialization.
Box 02 - Message Class Log/Print Status
The box 02 indicates that at least one message class has the
log/print status that is different from the backup status.
To change the log/print status for one or all message classes,
enter input message CHG:LPS,MSGCLS={a|ALL} with additional
parameters. (See AT&T 235-600-700, Input Messages Manual.) The
request will display CHG when recorded. This change will take
effect immediately with the request.
Entering the menu command 902 generates the input message
OP:LPS,MSGCLS=ALL and causes the status of the message classes
to be printed at the ROP.
Box 03 - MDII Reporting
The machine-detected interoffice irregularity (MDII) indicator
is backlighted when one or more MDIIs are inhibited. The
inhibits are generated by the TTY input message INH:MDII with
additional parameters. When the inhibit is invoked, it
suppresses the printing of MDIIs for the trunk group(s)
specified by the input message. The request will display INH
when recorded. This inhibit will take effect immediately with
the request.
Entering the 903 command generates the message OP:MDII, which
causes a listing of all suppressed trunk MDIIs to be printed at
the ROP.
Box 04 - Manual Recent Change
This indicator shows whether or not manual entering of recent
changes is inhibited.
When the command 604 is entered, the message INH:RC is
generated. The request will display INH when recorded. This
inhibit will take effect immediately with the request.
The allow command 704 generates the message ALW:RC. The request
will clear the text INH when recorded.
Since the Automatic Customer Station Rearrangement (ACSR)
feature depends upon Recent Change, if Recent Change is
inhibited, ACSR is also inhibited. During manual inhibits of
Recent Change, the RC box (box 04) is lighted and the CORC box
(box 05) is partially lighted.
Box 05 - Customer-Originated Recent Change (CORC)
The box 05 indicator shows whether CORCs are inhibited.
Box 05 is shared by CORCs and the ACSR feature. Since the ACSR
feature depends upon Recent Change, if Recent Change is
inhibited, ACSR is also inhibited. During manual inhibits of
Recent Change, the RC box (box 04) is lighted and the CORC box
(box 05) is partially lighted.
When a 905 command is entered, ACSR queuing is inhibited and
CORCs are allowed.
Box 06 - Recent Change Logging
The box 06 indicator shows whether or not the logging of
manually entered recent changes for all processors is inhibited.
This does not include customer-originated recent changes. Recent
Change logging may be inhibited in the event logging is causing
a problem, thereby allowing recent changes to be entered.
Unlogged changes are lost after a boot.
Entering the command 606 generates the message INH:RCLOG. The
request will display INH when recorded. This inhibit will take
effect immediately with the request.
Entering the command 706 generates the message ALW:RCLOG. The
request will clear the text INH when recorded.
Box 07 - Box 7 is not currently used.
Box 08 - Communication Link Normalization
If a fault occurs in one or more SM communication links, the
system will automatically try to restore the link(s) on a
periodic basis. This inhibit will suppress this action when
active.
Entering command 608 will generate the message INH:CLNORM. The
request will display INH when recorded. This inhibit will take
effect immediately with the request.
When the command 708 is entered, it generates the message
ALW:CLNORM. The request will clear the text INH when recorded.
Since attempts to restore CLNKS are periodic, there may be a
delay from the time an allow or inhibit request is recorded
until the allow or inhibit is recognized.
Box 09 - Centralized Automatic Message Accounting (CAMA)
Suspension
The box 09 indicator shows whether or not calls are being routed
through the CAMA operator number identification (ONI) process
for billing. Since inhibiting this indicator causes lost
revenue, a minor alarm is sounded when the inhibit is invoked.
Entering the command 609 generates the message INH:CAMAONI. The
request will display INH when recorded. This inhibit will take
effect immediately with the request.
Entering the command 709 generates the message ALW:CAMAONI. The
request will clear the text INH when recorded.
Box 10 - Trunk Hold
The box 10 indicator shows whether or not one or more trunk
groups are being monitored.
To monitor one or more trunk groups, the input message MON:TRUNK
must be entered. The request will display MON when recorded.
This monitoring will take effect immediately with the request.
The system looks for stop-go signaling failures in members of
monitored group(s). If a failure occurs, the member is held
off-hook and out of service for the craft to determine the
nature of the failure.
The input message CLR:TRUNK is entered to remove the stop-go
signaling.
Warning: This message will return all members back to
service, even if they failed. The request will
clear the text MON when recorded.
Entering the 910 command generates the input message OP:TRUNK,
which causes a listing of all trunk groups and members being
monitored to be printed at the ROP.
Boxes 11 Through 15 - Boxes 11 through 15 are not currently
used.
Box 16 - Routine Audits
The box 16 indicator shows if the automatic routine execution of
one or both AM application audit cycles (OKP or SMKP) are
inhibited.
The only way to obtain a single audit inhibit is via a TTY input
message in the message mode. (See INH:AUD=a,ENV=b in AT&T 235-
600-700, Input Messages Manual.) Single inhibits are not phase-
protected.
Entering the 616 command requests the inhibit of all audits and
generates the message INH:AUD=CYCLE,ENV. The request will
display INH when recorded. The request state does not
necessarily imply that the inhibit is in effect. Normally, the
status will follow the request within a short period of time.
If the 716 command is entered, the message ALW:AUD=CYCLE,ENV is
sent. The request will clear the text INH when recorded. The
request state does not necessarily imply that the inhibit has
been cleared. Normally, the status will follow the request
within a short period of time.
The command 916 (OP:AUD,STATUS=ALL,ENV=a) can be entered to get
the ROP listing of routine audit status for the application AM.
Box 17 - CM Routine Exercises
The box 17 indicator shows if any or all of the application
routine hardware exercises are inhibited in the communication
module (CM). Inhibits for routine exercises are effective for
only one exercise session. If the tests are in progress when the
message is received, the inhibit will not take place until the
next session.
Routine exercises are scheduled to run at specific times (for
example, daily at midnight). If inhibited exercises are allowed
after the scheduled time, the exercises are not started until
the next scheduled session.
When 617 is entered, the message INH:REX,CM is generated, which
inhibits all application CM routine exercises. The request will
display INH when recorded. This inhibit will take effect
immediately with the request.
If the command 717 is entered, the message ALW:REX,CM is
generated, which allows all application CM routine exercises.
The request will clear the text INH when recorded.
Entering the command 917 sends the message OP:REXINH,CM, which
generates a status listing at the ROP.
Note: These are application routine exercises and are
different from the routine exercises for the AM, as
shown on the EAI display.
Box 18 - Software Checks
The box 18 indicator reflects whether or not the AM application
software checks have been inhibited. The AM software checks and
the application software checks are different, but are
controlled together from manual commands.
The box 18 indicator can only be controlled from the EAI or TTY
input message INH:SFTCHK. This inhibit will prevent internal
software checks from causing initializations.
Entering the 618 command requests the inhibit of internal
software checks and generates the message INH:SFTCHK. The
request will display INH when recorded. The request state does
not necessarily imply that the inhibit is in effect. Normally
the status will follow the request within a short period of
time.
If the status is inhibited without being requested, the inhibit
was automatically applied by the system.
If the 718 command is entered, the message ALW:SFTCHK is sent.
The request will clear the text INH when recorded.
Box 19 - Min-Mode
The box 19 indicator shows the states of application min-mode.
When this box is backlighted, no call processing functions are
allowed in the AM. This is only used in extreme emergencies to
prevent customer actions from interfering with machine
operations.
Min-mode is invoked and deleted via EAI application pokes ``M''
and ``N,'' respectively.
The request will display INH when recorded. This inhibit will
take effect immediately with the request following the next
major AM initialization.
The request will clear the text INH when recorded and take
effect on the next major AM initialization.
Box 20 - Message Brevity Control
The box 20 indicator gives inhibit status of message brevity
control for all messages originating from the application
processes in the AM only.
Entering inhibit command 620 generates the message INH:BREVC,AM.
The request will display INH when recorded. This inhibit will
take effect immediately with the request.
Entering the allow command 720 generates ALW:BREVC,AM. The
request will clear the text INH when recorded.
This inhibit is cleared by any high-level AM initialization.
Box 21 - Recent Change Backout
The box 21 indicator shows whether or not uncommitted (recently
entered) AM recent changes are loaded or backed out. Backout can
only occur as a result of an AM high-level initialization.
The description portion shows when the recent changes are
actually backed out or loaded. If the backout is in progress, a
number will appear on the third line of the box showing the
progress of the backout. From 200 down to 100 is CORC backout;
200 meaning CORC is still fully backed out and 100 meaning CORC
is fully rolled forward. From 100 down to 0 is RC backout; 100
meaning RC is still fully backed out and 0 meaning RC is fully
rolled forward. Recent changes can be backed out only in
conjunction with a high-level initialization.
Recent changes should be backed out if a recent change is
suspected to be the cause of an AM performance problem.
When the command 421 is entered, the message SET:BACKOUT,RC,AM
is generated. The request will display SET when recorded. The
request state does not necessarily imply that the set is in
effect.
When the command 521 is entered, the message CLR:BACKOUT,RC,AM
is sent. The request will clear the text SET when recorded. The
request state does not imply that the backout has been cleared.
Box 22 - Emergency Action Interface/Miscellaneous Checks
The box 22 indicator shows if Emergency Action
Interface/Miscellaneous checks are inhibited. This box includes
hardware and error interrupts inhibits from the Emergency Action
Interface page and also error source inhibits.
When one of the messages INH:ERRINT or INH:ERRSRC is input, it
will cause the box to backlight. This box will also backlight
if error interrupt is inhibited on the Emergency Action
Interface page. Input messages ALW:ERRINT or ALW:ERRSRC will
allow the respective inhibits. Effective with the 5E8 software
release, the lower portion of this box is lighted if any error
interrupt inhibits have been inhibited or error source inhibits
are inhibited. If error interrupt checks are allowed unit by
unit, the indicator will not be cleared until the last unit is
allowed.
When the command 922 is entered, the message OP:ERRCHK is sent.
This generates a listing of the active inhibits.
Box 23 - Routine Maintenance
This indicator reflects whether or not a routine maintenance
function is inhibited. Should routine maintenance functions be
inhibited for an extended period of time, various system
resource availability and consistency may be adversely affected.
This indicator monitors the AM's Generated Key Collection and
Compression Routine inhibit status. If the routine is
inhibited, the description is backlighted.
When the 623 command is entered, the message INH:GKCCR,AM is
sent which requests that automatic executions of the Generated
Key Collection and Compression Routine be inhibited.
Entering command 723 generates the command ALW:GKCCR,AM which
requests that automatic periodic execution of the Generated Key
Collection and Compression Routine be allowed.
Box 24 - Hardware Checks
The box 24 indicator shows whether or not the AM/CM application
hardware checks have been inhibited. This indicator can only be
controlled from the EAI or by TTY input message INH:HDWCHK.
This inhibit will prevent maskable hardware faults from causing
recovery.
Entering the 624 command requests the inhibit of maskable
hardware faults and generates the message INH:HDWCHK. The
request will display INH when recorded. The request state does
not necessarily imply that the inhibit is in effect, since the
status will follow the request within a short period of time.
If the status is inhibited without being requested, the inhibit
was automatically applied to the system.
When the 724 command is entered, the message ALW:HDWCHK is sent.
The request will clear the text INH when recorded.
Box 25 - AM Routine Exercises
The box 25 indicator shows if any or all of the application
hardware routine exercises are temporarily inhibited in the AM.
Entering the 925 command sends the message OP:REXINH,AM which
generates a status listing of temporary AM REX inhibits to be
printed at the ROP. Temporary AM REX inhibits are not preserved
after a level 3 or level 4 AM initialization.
Entering the 925,PERM command sends the message
OP:REXINH,AM,PERM which generates a status listing of permanent
AM REX inhibits to be printed at the ROP. Permanent AM REX
inhibits are preserved through any level (1-4) of AM
initialization.
Boxes 26 and 27 - Boxes 26 and 27 are not currently used.
Figure .AW G308/ is an example of the 110 page display. The MANUAL RC
(box 04), REX CM (box 17), and REX AM (box 25) are inhibited.
The RC BACKOUT (box 21) is currently set and is partially backed
out (80%). However, the top line is normal video, and there is
no SET text after the 21. This indicates that the craft does not
desire the recent changes to be kept out.
In addition to the following commands, all available display
commands can be accessed from Display Page 110.

The purpose of the 115 display page is to provide a summary of
off-normal status for the hardware units and links which support
AM to SM(s) communication and provide paths for all circuit
switched calls.
The 115 display page has two separate and distinct versions.
The first version (Figure .AW G309/) is for offices with communication
module model 2 (CM2) hardware. The second version (Figure .AW G310/)
is for offices with CM1 hardware.
The 115 page provides overall status for MSGS 0, MSGS 1, MI/NC 0
(MI/LI/NC 0 for CM1), MI/NC 1 (MI/LI/NC 1 for CM1), TMS 0, TMS
1, communication links for the SMs, fan and fan fuse alarms for
the ONTCs (for the MSGSs and TMSs for CM1), the status of the
hardware check inhibit request bit, and the status of the
MI/NC/TMSs (MI/LI/NC/TMSs for CM1) functioning as a group
(ONTCCOM).
The ONTCCOM 0 includes MI 0 (and LI 0 in CM1), NC 0, and TMS 0.
The ONTC 0 includes ONTCCOM 0 and all DLIs on side 0. The
ONTCCOM 1 includes MI 1 (and LI 1 in CM1), NC 1, and TMS 1. The
ONTC 1 includes ONTCCOM 1 and all DLIs on side 1.
If an MSGS, MI/NC (MI/LI/NC in CM1), or TMSLNK has an off-normal
condition such as out-of-service (not family of equipment),
unavailable, hardware checks inhibited, etc., the appropriate
indicator giving the MCC page to see for detailed information is
backlighted. The phrase ``SEE PAGE XXXX IF BACKLIT'' is
backlighted when any of the boxes are backlighted to point out
that the numbers in the boxes are the page numbers to request.
Note: The 1210 boxes are backlighted only for NC
reference or oscillator problems.
The CLNKS indicator is a summary of the equipped SM
communication links status which is detailed on Page 1260.
The CLNKs are not TMSLNKs. A CLNK is a communication path
between the AM and an SM which passes through an MSCU, MMP, TMS,
TMSLNK, and DLI. The TMSLNKs connect the TMS to the DLI.
The backlighted indicator identifies the page necessary for
acting on the problem. As an example, the box with 1242
indicated is backlighted in Figure .AW G309/ because a module message
processor (MMP) on Display Page 1242 is shown as out of service
(OOS). The MMP out of service is also reflected on the MSGS 0
Page 1240, but going to 1240 would not be the final step to see
and act on the problem so the MSGS 0 box with 1240 indicated is
not backlighted. If a foundation peripheral controller (FPC) or
pump peripheral controller (PPC) was out of service also, then
the MSGS 0 box would backlight as shown in Figure .AW G310/. The
purpose of this strategy is to get the craft directly to the
problem with minimum paging. Therefore, if the 1240 (MSGS 0)
box and the 1241 (or 1242) were both backlighted, an out of
service (not family of equipment), an unavailable, an out-of-
service power, or an unavailable power condition would exist in
an MMP and an FPC, PPC, or MSCU.
The TMS 0 and 1 boxes (indicating Page 1220) will never
backlight. If a TMS is OOS, it would be due to the whole ONTC
being OOS or UNV; therefore, 1209 is the appropriate page to
display.
Effective with the 5E8 software release, AM and CM hardware
check inhibits have been separated. The system will not
implicitly set CM hardware check inhibits when AM hardware check
inhibits are requested. The indicator CM HDWCHK INH REQ only
appears on the page display if the data delivery request
automatic CM hardware check bit is set due to automatic
escalation or manual request. Presence of the indicator means
that there is a global inhibit request for all CM hardware
checks. This bit can be set manually by entering the input
message INH:HDWCHK,CM or by setting the application parameter to
`` f '' (or ``F'') on the EAI page. The bit can be cleared by
entering input message ALW:HDWCHK,CM or by resetting the
application parameter to ``g'' (or ``G'') on the EAI page.
Allowing hardware checks on all CM units individually will not
clear the bit, and the global indicator will remain on the page.
This means that at the next CM initialization, all CM
application hardware checks will be inhibited.
The CM isolation is available only in the CM2 version of Page
115. The indicator REQ CM ISOL appears on the page display to
signal that manual CM isolation has been requested. A separate
indicator, CM ISOL, is displayed when CM isolation is in effect.
Figure .AW G309/ shows an example of the CM2 Version with problems in
MI/NC 1, MSGS 0, TMS 0, CLNKS, and ONTC 1. Further information
on these problems would be found on display 1210 - MI/NC 0 & 1,
1242 - MSGS 0 - COMMUNITIES 2 - 7, 1221 - TMS 0 TMS LINKS 002 -
063, 1260 - CLNK SUMMARY, and 1209 - ONTC 0 & 1. There is a fan
alarm on ONTC 0 and the ONTC 1 fan fuse alarm is inhibited. The
CM ISOL indicator shows that CM isolation is in effect. Also,
CM HDWCHK INH REQ appears which signals that CM hardware check
inhibits have been requested.
Figure .AW G310/ shows an example of the CM1 Version with problems in
MI/LI/NC 1, MSGS 0, TMS 0, CLNKS, and ONTC 0. Further
information on these problems would be found on displays 1210 -
MI/LI/NC 0 & 1, 1240 - MSGS 0 SUMMARY, 1221 - TMS 0 - TMS LINKS
002 - 063, 1260 - CLNK SUMMARY, and 1209 - ONTC 0 & 1. There is
a fan alarm on MSGS 0, and the TMS 0 fan fuse alarm is
inhibited. The FPC DPLF indicator shows that duplex failure is
in effect.
There are no menu commands on the 115 display page. Commands for
removing, restoring, diagnosing, etc., are listed on the related
pages. There are no menu commands on the displays for fans or
fan fuses. For fans or fan fuses, see CLR:FANALM in AT&T 235-
600-700, Input Messages Manual.
All available display commands can be entered from the 115
display page.
The purpose of the 123 display page is to provide status and
maintenance commands for two DFCs and up to 16 moving head disks
(MHD). It also provides status and commands for disk
independent operation when both essential disks are lost. In
5E5 and later software releases, the 123 display page provides
status of the Auto MHD Configuration feature.
If there are more than two DFCs in the system, a second DFSA
page (Page 125) is used. The format of the 125 page is the same
as the 123 except the AUTO MHD CONFIGURATION status is not
shown; it appears only on Page 123.
The 123 page has three separate and distinct functions.
The first function of this page is to provide status and
maintenance commands for DFCs 0 and 1 and associated MHDs (up to
16). If the system is equipped with SCSI, this page also
provides status and maintenance commands for SBUSes (up to 4).
The second function is to provide status and commands during
disk independent operation (DIOP). When both of the MHDs that
are marked E (essential) go out of service, this page is
automatically displayed. This is called full DIOP. The
appropriate menu commands to use under these circumstances are
the 600 series of commands. When in full DIOP (Figure .AW G312/), a
620 command will appear which will allow the MHD to be reloaded
from tape without bringing down call processing during the
reading of the tape. When the MHD has been reloaded, a minimum
of a 52 boot is required. The other 600 series commands, with
the exception of the 699 poke, may be used also when not in
DIOP. The 699 poke works only in full DIOP. Effective in 5E7,
both the 602 poke to restore the DFC controller and the 604 poke
to restore the SBUS controller require UCL when the system is in
full DIOP. These pokes (602/604) will not restore associated
subunits (MHDs) to prevent accidental disk restoral during disk
maintenance.
If only one of the essential MHDs goes out of service, the MHDs
are in simplex operation (Figure .AW G311/), but the page is not
automatically displayed.
During full DIOP, the area at the bottom of the page between the
two horizontal lines will display output messages for the 600
series menu commands.
The third function of the 123 page, in 5E5 and later software
releases, is to provide for the display of the Automatic MHD
Configuration feature. The AUTO MHD CONFIGURATION data
displayed on 123 page is a summary status of information from
Pages 178, Auto Spare Disk, and 179, Disk Configuration.
Possible values of the Automatic MHD Configuration feature are
as follows:
a. AUTO MHD CONFIGURATION READY: The feature is armed and
ready to run if needed.
b. SEE PAGE 179, CONFIG MHDs ...: The listed MHDs have been
reconfigured; see Page 179 for more data.
c. AUTO MHD CONFIGURATION OFF: The feature is turned off.
d. MHD CONFIG INHIBITED, SEE PAGE 178: The feature is blocked
on one or more MHDs or the entire office; see Page 178 for
more data.
e. MHD CONFIG IN PROGRESS, SEE PAGE 178: An MHD configuration
is in progress; see Page 178 for more data.
There are two columns of notations on the right side of each of
the MHD status columns. The first of the two columns contains
one of the following two letters:
o Y - (Yes): This means the MHD was diagnosed or restored
since the last system initialization and appears to be
usable.
o N - (No): This means the MHD was not diagnosed or restored
since the last system initialization and does not appear to
be usable.
The second column contains the letter E which signifies that the
associated MHD is essential.
The upper two display fields, OPTION LEVEL and CURRENT LEVEL,
inform the user of the optional disk independent operation
feature level selected for the operating system and the current
disk independent operation state the operating system is in.
The OPTION LEVEL displayed will be one of the following:
o NODIOP: Disk independent operation feature is not
selected.
o DIOP: Conditional disk independent operation is selected.
o UCLDIOP: Unconditional disk independent operation is
selected.
The CURRENT LEVEL displayed will be one of the following:
o NORMAL: Normal operating system without disk independent
operation mode.
o SIMPLEX: Operating system running with at least one
essential MHD out of service.
o DUPLEX: Operating system is running with all duplex
essential MHDs active.
o CONDITIONAL DIOP: Operating system is in conditional disk
independent operation mode with the last remaining duplex
essential MHD about to be removed from service.
o FULL DIOP: Operating system is running with a duplex
essential pair of MHDs out of service.
For each unit displayed, the following information is shown:
o Major state of the unit
o Minor state of the unit (if available)
o Usability of the unit (Y = usable, N = unusable)
o Essential status of the unit (E = essential, M = manually
nonremovable, blank = nonessential)
o Microcode status (Firmware of Pumpcode) for the DFC
o Overload status of a DFC.
Figure .AW G311/ shows the simplex version of the disk file system
access page for an office with SMD only. In this example, one
of the essential MHDs (MHD 1) is OOS, so the current level is
marked as SIMPLEX. The OOS MHD caused the AM PERPH indicator at
the top of the page to be backlighted. The automatic MHD
configuration feature is ready.
When the simplex mode is entered, the system begins to lock
essential, nonswappable processes from disk into core (AM
memory). Upon completion of the locking process, the system
will print the message, REPT DIOP SIMPLEX PROCESSING COMPLETED.
If the system has problems in locking the essential processes
into core, it will print the message, REPT DIOP SIMPLEX UNSWAP
FAILURE PID=xx (xx = utility ID of process that failed to lock
into memory). This message will reprint every 5 minutes until
the locking process is completed.
Figure .AW G312/ shows the FULL DIOP version.
Figure .AW G313/ shows the simplex version of the disk file system
access page for an office with SCSI only or with both SMD and
SCSI.
The only difference between the SCSI-DFSA and SMD-DFSA versions
of the 123 page is the addition of ``SBUS 0 SBUS 2'' under DFC
0, ``SBUS 1 SBUS 3'' under DFC 1 on the SCSI version, and the
604 command for RST/RMV SBUS.
Commands are provided to remove, restore, and diagnose the MHDs
and to take appropriate actions on the MHDs when one or more
essential MHDs are out of service.
All available displays can be accessed from the 123 page.

The purpose of the 125 display page is to provide status and
maintenance commands for two DFCs and up to 16 moving head disks
(MHD). It also provides status and commands for disk
independent operation when both essential disks are lost.
This page exists only when there are more than two DFCs in the
system.
The format of the 125 page is the same as the 123 except the
AUTO MHD CONFIGURATION status is not shown; it appears only on
Page 123.
The 125 page has two separate and distinct functions.
The first function of this page is to provide status and
maintenance commands for DFCs 2 and 3 and associated MHDs (up to
16). If the system is equipped with SCSI, this page also
provides status and maintenance commands for SBUSes (up to 4).
The second function is to provide status and commands during
disk independent operation (DIOP). When in full DIOP, the 125
page will be accessible. The 620 poke (reload from tape option)
will only work on the 123 page. The other 600 series commands,
with the exception of the 699 poke, may be used also when not in
DIOP. The 699 poke works only in full DIOP. Effective in 5E7,
both the 602 poke to restore the DFC controller and the 604 poke
to restore the SBUS controller require UCL when the system is in
full DIOP. These pokes (602/604) will not restore associated
subunits (MHDs) to prevent accidental disk restoral during disk
maintenance.
If only one of the essential MHDs goes out of service, the MHDs
are in simplex operation (Figure .AW G314/), but the page is not
automatically displayed.
During full DIOP the area at the bottom of the page between the
two horizontal lines will display output messages for the 600
series menu commands.
There are two columns of notations on the right side of each of
the MHD status columns. The first of the two columns contains
one of the following two letters:
o Y (Yes): This means the MHD was diagnosed or restored
since the last system initialization and appears to be
usable.
o N (No): This means the MHD was not diagnosed or restored
since the last system initialization and does not appear to
be usable.
The second column contains the letter E which signifies that the
associated MHD is essential.
Figure .AW G314/ shows the simplex version of the disk file system
access page for an office with SMD only. In this example, one
of the essential MHDs (MHD 17) has gone out of service, so the
current level is marked as SIMPLEX. The OOS MHD caused the AM
PERPH indicator at the top of the page to be backlighted.
When the simplex mode is entered, the system begins to lock
essential, nonswappable processes from disk into core (AM
memory). Upon completion of the locking process, the system
will print the message, REPT DIOP SIMPLEX PROCESSING COMPLETED.
If the system has problems in locking the essential processes
into core, it will print the message, REPT DIOP SIMPLEX UNSWAP
FAILURE PID=xx (xx = utility ID of process that failed to lock
into memory). This message will reprint every 5 minutes until
the locking process is completed.
Figure .AW G315/ shows the simplex version of the disk file system
access page for an office with SCSI only or with both SMD and
SCSI.
The only difference between the SCSI-DFSA and SMD-DFSA versions
of the 125 page is the addition of ``SBUS 0 SBUS 2'' under DFC
2, ``SBUS 1 SBUS 3'' under DFC 3 on the SCSI version, and the
604 command to RST/RMV SBUS.
Commands are provided to remove, restore, and diagnose the MHDs
and to take appropriate actions on the MHDs when one or more
essential MHDs are out of service.
All available displays can be accessed from the 125 page.

There will be a maximum of two DFCs on a DFSA performance page.
If there are more than two DFCs in the system, a second DFSA
performance page (Page 128) is used.
The 126 page can show either SMD-DFSA or SCSI-DFSA, depending on
the feature option of the operational office.
With the SCSI feature, the DFSA performance data is not
available when the operating system is in disk independent
operation (DIOP) mode.
Meanings of the performance fields displayed are as follows:
o CMP: Jobs completed by the DFC for the unit. This field
is normalized to show the number of jobs that were
completed per second.
o AVG: The average size of the jobs completed for a unit
(number of disk blocks).
o MAX: The maximum size of a job completed in a time
interval (number of disk blocks).

The 131 page display is a menu page that contains a list of call
trace poke commands.
A ``SEE PAGE'' indicator on the 131 menu page shows the
maintenance personnel which hardware call trace page (133
through 140, 150, or 151) to access for the details of the call
trace.
The 131 menu page gives the user the ability to invoke a trace
by simply entering a poke value followed by a number or a set of
numbers. For example, 401,2220001 where 401 is the poke for a
utility hardware call trace with a directory number (DN),
2220001, being the input option.
When tracing an Integrated Services Digital Network (ISDN)
circuit switched lines, the channel to be traced should be
included in the input. If no channel is specified, then the
default action is to trace the D-channel. See pokes 401 and 405
for input requirements.
The subaddress (SA) option is used to specify which subaddress
of a DN/MLHG with multiple call appearances to trace.
Specifying SA=ALL will result in Page 150 being populated with
the status of all valid subaddresses for the given input. If
the SA option is used, the channel (CH) option must be omitted.
The SA option is valid for voice calls on terminals which use
subaddresses. This includes most custom digital subscriber
lines (DSL) and also standard Electronic Key Telephone Service
(EKTS) lines. To trace packet switched calls, the PKT variable
is included in poke commands 401, 404, 405, 406, and 410.
The call ID number (CID) option is used to specify which call on
a standard non-EKTS DSL to trace, or to trace circuit switched
data calls on any type terminal. Specifying CID=ALL will result
in Page 150 being populated with the status of all calls for the
given input. If the CID option is used, the channel (CH) option
must be omitted.
The CID and SA options are mutually exclusive. If an incorrect
option is used for the call type of the given input, an error
message will be generated, and the 150 page will be populated
with the correct information for the input DN/MLHG. Refer to
the 150 page for more detailed information.
Figure .AW G319/ shows an example of the 131 page display for 5E8.
All poke commands that appear on the 131 display page can be
invoked by maintenance personnel, and they can also be invoked
from any of the call trace display pages (131-140, 150, and
151). Refer to Page 132 - Call Trace Menu Cont. (Figure .AW G320/)
for more call trace poke commands. The 131 page must be used to
access the other call trace pages from a page that is not a call
trace page.
Effective with the 5E5 software release, the 132 page is a
continuation of the 131 menu page consisting of a list of call
trace poke commands. The 132 Hardware Call Trace page was moved
to Page 140.
A ``SEE PAGE'' indicator on the 132 menu page shows the
maintenance personnel which hardware call trace page (133-140,
150, or 151) to access for the details of the call trace.
The 132 menu page gives the user the ability to invoke a trace
by simply entering a poke value followed by an option or a set
of numbers. For example, to trace the active loop of the B1
channel of the operator position terminal 1-135, the poke would
be 418,1,135,loop=0,ch=B1.
When the 440 poke is used to trace a process id, the process id
to trace must be for either a circuit switched voice call or a
circuit switched data call.
Figure .AW G320/ shows an example of the 132 page display.
All poke commands that appear on the 132 display page can be
invoked by maintenance personnel, and they can also be invoked
from any of the call trace display pages (131-140, 150, and
151). Refer to Page 131 - Call Trace Menu (Figure .AW G319/) for more
call trace poke commands. Also, any call trace display page can
be accessed from the 132 display page.
The hardware call trace page displays (133 through 138) show the
hardware paths of calls requested to be traced.
Call Trace Pages 133 through 138 provide a ``snapshot'' of the
hardware and software path(s) involved with a call. Page 133 is
the main UTILITY CALL TRACE display. Some calls require several
displays, for example, a 3-way call. A ``SEE PAGE'' indicator
appears if more displays are involved in a particular call.
Information collected about dynamic data structures and hardware
paths can aid in trouble-shooting a failed call. The software
state, external identifier, peripheral path, and network path
are shown for each connection of the call and are described as
follows:
o Software state: The software state represents the state of
the call (ringing, talking, transient, etc.) as stored in
the process control block link area (PCBLA).
o External identifier: The external identifier is the
representation of the customer and can include the
following:
-- Directory Number (DN)
-- Multiline Hunt Group (MLHG) group and member
-- Trunk (TRK) group and member
-- Equipment Number (EN).
o Peripheral path: The peripheral path displays the hardware
path taken by the call from the peripheral unit through the
service units to the Time Slot Interchanger (TSI).
o Network path: The network path is represented by the
Network Control and Timing (NCT) time slot connecting the
TSI to the Time Multiplexed Switch (TMS). The connection
from the NCT to the TMS is shown as either a solid line,
representing an inter-SM call, or a dotted line,
representing an intra-SM call.
If a call that uses an ISLU is traced, the type of circuit
switched service (voice or data) and a B-channel identifier (B-
1, B-2, or ON HOLD) are displayed. The ON HOLD means that no
B-channel is allocated for the call.
For an OSPS call through a remote ISLU (RISLU), the connection
via a T1 carrier between the DLTU remote (DLTUR) in the RISLU
and the DLTU host (DLUTH) in the switch will be shown.
Additionally, if business and residence custom services (BRCS)
features are assigned to a DSL, the primary directory number
(PDN), subaddress (SA), and call appearance (CA) will be
displayed.
Effective with the 5E8 software release, standard ISDN DSLs are
supported. If a standard EKTS DSL is traced, the SA and CA are
displayed as for a custom DSL. If a standard non-EKTS is
traced, SA and CA do not apply.
The Integrated Digital Carrier Unit (IDCU) is also supported for
the 5E8 software release. Call Trace displays the SM and IDCU
numbers for an IDCU.
The IDCU peripheral unit contains a time slot interchange unit
(TSIU) which offers the ability to make connections without
using the TSI in the SM, thus saving SM time slot resources. A
trace of this hairpin connection only shows the RT and the IDCU.
The IDCU also supports the PUB43801 interface format used for
interfacing to D4 and D5 channel banks and to Digital Access
Cross Connect Systems (DACS). Since these connections do not
use an RT, RT is not shown on the trace.
Examples of Hardware Call Trace displays are as follows:
o Figure .AW G321/ - Multipoint DSL to ISDN PODS
o Figure .AW G322/ - Analog DN to an Analog Trunk
o Figure .AW G323/ - Hairpinned IDCU PUB43801
o Figure .AW G324/ - OSPS OPT
o Figure .AW G325/ - RSM Inter Cluster Link (ICL)
o Figure .AW G326/ - Subscriber Loop Carrier to Analog IDCU DN
o Figure .AW G327/ - RSM to HSM.
Refer to 131 - Call Trace Menu display (Figure .AW G319/) for the
complete list of call traces that can be invoked (by poke
commands) from the 133 through 138 page displays. Also, all
available page displays can be invoked from the 133 through 138
page displays.
The purpose of the 140 page display is to provide the hardware
connections for the packet call trace and circuit switch D-
channel call trace.
Effective with the 5E5 software release, Page 140 is the same as
Page 132 for the 5E4 software release. The only difference is
that additional displays are available for Multipoint DSLs.
Note: The PDB abbreviation on the 140 page display
actually means protocol handler data bus (PHDB).
The PDB abbreviation appears on the page display
because an internal software process is also named
PHDB.
Figure .AW G328/ is an example of a circuit switched D-Channel trace
of a Multipoint DSL.
Figure .AW G329/ is an example of an X.75' packet switched Hardware
Call Trace.
Figure .AW G330/ is an example of an IDCU D-channel Hardware Call
Trace. The IDCU is new with the 5E8 software release.
Refer to Page 131 - Call Trace Menu (Figure .AW G319/) and Page 132 -
Call Trace Menu Cont. (Figure .AW G320/) for the complete list of call
trace poke commands that can be invoked. Also, any call trace
page display can be accessed from the 140 menu page.
The purpose of the 141 through 144 display pages is to provide a
more detailed summary status of groups of 48 SMs on one display.
Displays 141, 142, 143, and 144 are very similar. Each one can
display summary status of up to 48 SMs. Page 141 displays status
for SMs 1 through 48, Page 142 displays summary status for SMs
49 through 96, Page 143 displays status for SMs 97 through 144,
and Page 144 displays summary status for SMs 145 through 192.
Each equipped SM has a unique indicator on these displays. Each
indicator has the following three distinct sections:
o SM NUMBER: There may be gaps in SM numbering for a
particular office. To provide flexibility in office
numbering schemes, the SM numbers are not necessarily
assigned sequentially. If an SM is not equipped, it is not
shown. An example of this is shown in the 141 page example
(Figure .AW G331/) by the blank indicators between SM 12 and SM
20, SM 20 and SM 24, etc.
o SM TYPE: There is a 3-character acronym to show how an SM
is being used. For example, an LSM is a local switching
module.
o SM STATUS PHRASE: This is a 10-character, maximum, phrase
which describes the most significant off-normal condition
in the SM. During initialization, the status phrase will
give the current initialization progress type. Table .AW TAN/
lists status phrases in order of priority and gives the
color and an explanation for each phrase. New status
phrases for 5E8 are TMCRST and EOCRST which indicate
restore in progress for IDCU RT Time Slot Management
Control and IDCU RT Embedded Operations Channel,
respectively. For detailed information on SM progress
markers, see AT&T 235-105-250, System Recovery.
If more than one off-normal condition exists in an SM, a ``+''
will appear to the right of the status phrase (SMs 1, 5, and 48
in Figure .AW G331/). A complete list of active off-normal conditions
can be output via menu command 900.
In addition to this page, the status phrase is shown on all
per-SM pages.
When a new alarm condition on an SM occurs, the SM indicator
will begin flashing. The ALM RLS key will not stop the flashing.
The color of the flashing will reflect the new alarm only if the
newly recorded condition is of higher or equal priority to the
previous condition. To stop the flashing, the craft should
display the 1010 page for that SM. There is also a command to
retire the flashing for the range of SMs associated with the
page being displayed - 999. This is mainly provided for
situations such as during installation when SMs are being grown
and many SMs are displaying recurrent error conditions.
The backlighted note about the DLIs appears whenever an ONTC is
out of service or unavailable. The DLIs are under the
maintenance control of the ONTCs, thus all DLIs on a side are
affected when the ONTC of that side is off-normal.
For further details on any SM recovery-related activity or SM
inhibits, the craft would enter 1800,X to display the SM X
INHIBIT AND RECOVERY CONTROL page. This is the SMs control page
for emergency action.
For details on circuits out of service or hardware in a
particular SM, the craft would enter 1010,X to display the SM X
STATUS page. This page can be accessed during the initialization
of SM X or if SM X is isolated, but the only status that will
fill in are the SM STAT and RELATED PAGES boxes.
For details on ONTC circuits out of service, the craft would
enter 115 to display the COMMUNICATION MODULE SUMMARY page.
In the example of the 141 page shown in Figure .AW G331/, SM 1, which
is an LSM, has several off-normal conditions. The ``+''
indicates that there is more than one off-normal condition. For
the most critical condition, inhibits are set. Both SM 3 and 10
have circuits out of service. The SM 5, an RSM, has a hash
error plus other off-normal conditions. The SM 06, another LSM,
is isolated. This indicator would be flashing in the display,
which cannot be shown here. The SM 48, another RSM, has a
building power alarm plus other off-normal conditions. There is
an off-normal condition in ONTC 1 causing all the DLIs on Side 1
to be off-normal.
All available displays can be accessed from the 141 through 144
display pages.

The 150 page display provides status information on all
circuit-switched calls of a particular directory number (DN) or
multiline hunt group (MLHG) member.
Effective with the 5E8 software release, the 150 page was
enhanced to display call ID (CID) information in addition to the
subaddress (SA) information displayed in earlier software
releases. Accordingly, the title of the page was changed from
SUBADDRESS STATUS to TRACEABLE CALL STATUS.
A ``SEE PAGE'' indicator in the upper right corner of the 150
page identifies associated page displays to access for
additional call trace information.
Subaddress Displays
For custom DSLs and standard Electronic Key Telephone service
(EKTS) DSLs, information is provided on each subaddress of the
given DN/MLHG. The SA number corresponds to button location on
the terminal; it is not the same as call appearance (CA) number,
but they are related values. The first CA of a DN/MLHG at the
terminal is SA 0. The SA values are then incremented for each
subsequent appearance of the same DN/MLHG at the terminal. A
maximum of 16 SAs can be assigned per DN/MLHG.
The SA information is shown in four columns on the 150 page and
includes the following:
