UDS1-BD (UDS1 Interface Circuit Pack)
Issue 4 May 2002
10-1871 555-233-123
1313 FAIL The UDS1 circuit pack could not deactivate a CPE Loopback Jack
loopback.
1. Execute the test ds1-loop UUCSS end-loopback/span-test
command.
2. If the attempt to deactivate the CPE Loopback Jack is not
successful, check the cabling and investigate the problem at
the CPE Loopback Jack.
3. Run the test again.
1314 FAIL The UDS1 circuit pack could not deactivate a far-end CSU
loopback.
1. Execute the test ds1-loop UUCSS end-loopback/span-test
command.
1320 FAIL A CSU Module/Sync Splitter hardware failure, or an ICSU/Sync
Splitter serial interface audit failure was detected by the UDS1
circuit pack.
1. Replace the CSU module/Sync Splitter, and then run the test
again.
2. If the test continues to fail with this error code, replace the
UDS1-BD circuit pack and run the test again.
3. If the test continues to fail with this error code, then the
problem could be in the I/O cable between the backplane and
the CSU module/Sync Splitter.
1321 FAIL DTE LOS (loss of signal) was detected between the UDS1 board
and the CSU Module or the Sync Splitter. Either the UDS1 board,
the CSU Module/Sync Splitter, or the I/O cable between the
backplane and the CSU module/Sync Splitter (or any combination
thereof) has failed. Attempt to isolate the problem to one of these
areas.
1. Replace the CSU Module/Sync Splitter and run the test
again.
2. If the test continues to fail with this error code, then replace
the UDS1-BD board and run the test again.
3. If the test continues to fail with this error code, the problem
could be in the I/O cable between the backplane and the CSU
module/Sync Splitter.
