DS1-BD (DS1 Interface Circuit Pack)
Table 227. TEST #138 Loss of Signal Alarm Inquiry Test — Continued
Error Test
Code Result
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 test ds1-loop UUCSS ds1/csu-loopback-tests.
1313 FAIL The TN767E circuit pack could not deactivate a CPE Loopback Jack
loopback.
1314 FAIL The TN767E circuit pack could not deactivate a far-end CSU loopback.
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.
555-233-119
Description/ Recommendation
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.
1. Execute test 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.
1. Execute test ds1-loop UUCSS end-loopback/span-test.
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.
