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.
