Error Test
Code Result
1311 FAIL The Integrated CSU (I-CSU) Module Equipment Loopback (ELB) test
(#1210) failed. This test is executed by the I-CSU during I-CSU
power-up/reset (i.e., the UDS1 board is physically inserted and a CSU
Module or a Sync Splitter is already installed) or when the CSU Module/Sync
Splitter is plugged on to an already initialized DS1 board. The ELB test is also
executed as part of the command test ds1-loop UUCSS
ds1/csu-loopback-tests for the CSU Module and T1 Sync Splitter.
1312 FAIL The Integrated CSU (I-CSU) Module Repeater Loopback (RLB) test (#1211)
failed. This test is executed during I-CSU/Sync Splitter power-up/reset (i.e.,
the UDS1 board is physically inserted and the CSU Module or the Sync
Splitter is already installed) or when the CSU Module/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 for the
CSU Module/T1 Sync Splitter.
1313 FAIL The UDS1 circuit pack could not deactivate a CPE Loopback Jack loopback.
1314 FAIL The UDS1 circuit pack could not deactivate a far-end CSU loopback.

Description/ Recommendation
1. Execute the test ds1-loop UUCSS ds1/csu-loopback-tests command.
2. If the ELB test continues to fail, then either the UDS1 board, the CSU
Module/T1 Sync Splitter, or the I/O cable between the backplane and the
CSU module/T1 Sync Splitter (or any combination thereof) has failed.
Attempt to isolate the problem to one of these areas. Begin by replacing
the CSU Module/T1 Sync Splitter and running the test ds1-loop UUCSS
ds1/csu-loopback-tests command again.
3. If the ELB test continues to fail, then replace the UDS1 board and run the
test ds1-loop UUCSS ds1/csu-loopback-tests command again.
4. If the ELB test continues to fail, the problem could be in the I/O cable
between the backplane and the CSU module/T1 Sync Splitter.
1. Execute the test ds1-loop UUCSS ds1/csu-loopback-tests command.
2. If the RLB test continues to fail, then replace the CSU Module/T1 Sync
Splitter.
3. Run this test again.
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.
1. Execute the test ds1-loop UUCSS end-loopback/span-test command.
