1311 FAIL The Integrated CSU (I-CSU) Module Equipment Loopback (ELB) test (#1210)
failed. This test is executed by the ICSU during ICSU power-up/reset (TN767E
board physic ally inserted and 120A CSU Mod ule already installed) or when
the 120A CSU Module 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.
1. Execute test ds1-loop UUCSS ds1/csu-loopback-tests.
2. If the ELB test continues to fail, then either the TN767E board, the CSU
Module, or the I/O cable between the backplane and the CSU module (or
any combination thereof) has failed. Attempt to isolate the problem to one
of these areas. Begin by rep lacing the CSU Module and running the
t
est
ds1-loop UUCSS ds1/csu-loopback-tests command again.
3. If the ELB test continues to fail, then replace the TN767E board and run
test ds1-loop UUCSS 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.
1312 FAIL The Integrated CSU (I-CSU) Module Repeater Loopback (RLB) test (#1211)
failed. This test is executed by the ICSU during ICSU power-up/reset (TN767E
board physic ally inserted and 120A CSU Mod ule already installed) or when
the 120A1 CSU Module 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.
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 prob lem 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.
