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.- TN464F board physically inserted and 120A1 CSU
Module already installed) or when the 120A1 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 PCSS ds1/csu-loopback-tests .
1. Execute the
test ds1-loop PCSS ds1/csu-loopback-tests command.
2. If the ELB test continues to fail, then either the TN464F 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 replacing the CSU Module and
running the
test ds1-loop PCSS ds1/csu-loopback-tests command
again.
3. If the ELB test continues to fail, then replace the TN464F board and
run the
test ds1-loop PCSS 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.
1312 FAIL The Integrated CSU (I-CSU) Module Repeater Loopback (RLB) test
(#1211) failed. This test is executed by the I-CSU during I-CSU
power-up/reset (i.e.- TN464F board physically inserted and 120A1 CSU
Module 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
test ds1-loop PCSS ds1/csu-loopback-tests .
1. Execute the
test ds1-loop PCSS ds1/csu-loopback-tests command.
2. If the RLB test continues to fail, then replace the CSU Module.
3. Run this test again.
1313 FAIL The TN464F circuit pack could not deactivate a CPE Loopback Jack
loopback.
1. Execute the
test ds1-loop PCSS end-loopback/span-test command.
2. If the attempt to deactivate the CPE Loopback Jack loopback is not
successful, check the cabling and investigate the problem at the CPE
Loopback Jack.
3. Run the test again.
1314 FAIL The TN464F circuit pack could not deactivate a far-end CSU loopback.
1. Execute the
test ds1-loop PCSS end-loopback/span-test command.
2. If the attempt to deactivate the far-end CSU loopback continues to fail,
then escalate the problem.
