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 ins erted 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 UUCSS
ds1/csu-loopback-tests
.
1. Execute the
test ds1-loop UUCSS 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 UUCSS 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 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.
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 ins erted 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 UUCSS
ds1/csu-loopback-tests
.
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.
3. Run this test again.
1313 FAIL The TN464F circuit pac k could not deac tivate a CPE Loopback Jac k loopback.
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 p roblem 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 UUCSS end-loopback/span-test
command.
