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 UDS1 board. The ELB test is also
executed as part of test ds1-loop location ds1/
csu-loopback-tests for the CSU module and T1 sync splitter.
1. Execute the test ds1-loop location 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. Replace
the CSU module/T1 sync splitter and run test ds1-loop
location ds1/csu-loopback-tests again.
3. If the ELB test continues to fail, replace the UDS1 board, and run
test ds1-loop location ds1/csu-loopback-tests 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.
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 UDS1 board. The RLB test
is also executed as part of test ds1-loop location ds1/
csu-loopback-tests for the CSU module/T1 sync splitter.
1. Execute test ds1-loop location 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.
