1312 FAIL The Integrated CSU (I-CSU) Module Repeater Loopback (RLB) test (#1211)
failed. This test is executed during ICSU/T1 Sync Splitter power-up/reset (the
TN767E board is physically inserted and the CSU Module/T1 Sync Splitter is
already installed), or when the 120A1 CSU Module/T1 Sync Splitter is plugged
on to an already initialized DS1 board. The RLB test is also executed as part of
the command
t
est ds1-loop UUCSS ds1/csu-loopback-tests.
1. Execute test ds1-loop UUCSS ds1/csu-loopback-tests.
2. If the RLB test continues to fail, then replace the CSU Module/T1 Sync
Splitter.
3. Run this test again.
1313 FAIL The TN767E circuit pack could not deactivate a CPE Loopback Jack
loopback.
1. Execute
t
est ds1-loop UUCSS end-loopback/span-test.
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 TN767E circuit pack could not deactivate a far-end CSU loopback.
1. Execute test ds1-loop UUCSS end-loopback/span-test.
1320 FAIL A CSU Module/T1 Sync Splitter hardware failure or an ICSU/T1 Sync Splitter
serial interface audit failure was detected by the TN767E DS1 circuit pack.
1. Replace the CSU Module/T1 Sync Splitter, and then run the test again.
2. If the test continues to fail with this error code, replace the TN767E 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/T1 Sync Splitter.
1321 FAIL DTE LOS (loss of signal) was detected between the TN767E DS1 board and
the 120A1 CSU Module or the T1 Sync Splitter. Either the TN767E board, the
120A1 CSU Module/T1 Sync Splitter, or the I/O cable between the backplane
and the 120A1 CSU Module or the 401A T1 Sync Splitter (or any combination
thereof) has failed. Attempt to isolate the problem to one of these areas.
1. Replace the CSU Module/T1 Sync Splitter and run the test again.
2. If the test continues to fail with this error code, then replace the TN767E
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 120A1 CSU Module or the 401A
T1 Sync Splitter.
