Troubleshooting
6. Configure the customer data entry forms
- If you are installing the CEPT or DS1/T1 Formatter II 
variants, deprogram the previous CEPT or DS1 card 
and reprogram the new card in the System 
Configuration form. The CEPT Formatter II card and 
the DS1/T1 Formatter II cards are identified as 
“Universal E1” and “Universal T1” respectively.
-  Program the CEPT or DS1/T1 Formatter II cards the 
same as for regular trunk programming.
It is recommended that you leave the jumpers on the 
CEPT and DS1/T1 Formatter II cards at the default 
setting of Line Side Termination.
7. Install the Interface Assembly
-  Attach the anti-static strap to your wrist.
-  Unpack the Interface Assembly and ensure it is not 
damaged.
-  At the rear of the cabinet, locate the DSU slot that 
corresponds to the slot that you will use for the 
replacement CEPT or DS1/T1 Formatter card.
-  Mount the Interface Assembly extension bracket. The 
closed side of the extension bracket must be to the left 
when viewed from the rear of the cabinet.
-  Insert the Interface Assembly. Ensure the edge 
connector on the card aligns with the connector on the 
backplane of the system.
-  Secure the Interface Assembly to the extension 
bracket with the screws provided.
8. Install the CEPT or DS1/T1 Formatter I or II Card (see 
“Installing a Card” on page 146).

9. Test the card
- Inspect the faceplate LEDs to verify that the card is 
functioning.
Note:The replacement cards may take longer to boot-up than older card 
versions.
- Open a maintenance window and verify that the trunks 
associated with the corresponding channels are all in 
idle state.
10. Upgrade or re-install the software:
Upgrades for the CEPT and DS1/T1 Formatter II cards 
are done from the main controller each time its software 
is upgraded. You can also use the force dl command 
option in the VT 100 emulation window.
The CEPT and DS1/T1 Formatter I cards are not 
upgradeable in the field as they come with the software 
pre-loaded.
11. Reset the CEPT or DS1 Formatter I or II card using one 
of the following methods:
-  Entering the LOAD  command in the 
maintenance window of the system.
-  Unseat and reseat the card.
-  Type the reset option command in the VT 100 
emulation window.

Checking a Non-redundant System
1. Log on to the maintenance terminal and select 
maintenance mode.
2. Enter the following commands:
SH ST ALChecks for system alarms. There 
should be no alarms. If alarms are 
present, see Flowchart 3: An Alarm is 
Present on page 120.
DBMS STATChecks the status of the initialized 
flag. The flag should be on if the 
system is in sync. If the flag is off, 
enter DBMS SAVE from the active 
plane.
PROG R DISDisplays the scheduled system 
reset. By default, the system reboots 
at 2:15 a.m. daily ONLY IF there is 
memory fragmentation. To force a 
system reboot at the scheduled time, 
see Scheduling a System Reboot 
(Non-redundant Systems) on page 
95.
ME SChecks the status of the 
communication links. All 
communication links should be open.
PCM TOChecks for circuit switch link faults. 
There should be no faults.
DBMS CH FChecks the sanity and current status 
of the system. The number of 
detected errors should be zero. 
Otherwise, there is a problem with 
the database and immediate steps 
should be taken to begin recovery.
Note: This step takes 60 seconds to 
complete.

Checking a Redundant System
1. Log on to the maintenance terminal and select 
maintenance mode.
2. Enter the following commands (first from the active 
plane, then from the inactive plane):
FIL STAT REDIndicates whether the database on 
both drives are IN SYNCH, OUT OF 
SYNCH, or ISOLATED. The 
databases should be IN SYNCH. If 
both planes are not IN SYNCH, see 
Table 25: Status of Redundant File 
System on page 125.
Note: It takes approximately 15 
minutes for both planes to become 
synchronized.
DBMS STATChecks the status of the initialized 
flag. The flag should be on. If the flag 
is off, enter DBMS SAVE (first from 
the active plane and then from the 
inactive plane).
DBMS CH FChecks the sanity and current status 
of the system. The number of 
detected errors should be zero. 
Otherwise, there is a problem with 
the database and immediate steps 
should be taken to begin recovery.
Note: Check the active and inactive 
planes. This step takes 60 seconds 
to complete.
3. Enter the following commands from the active plane:
SH ST ALChecks for system alarms. There 
should be no alarms. If alarms are 
present, see Flowchart 3: An Alarm is 
Present on page 120.
