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
TN464F board is physically inserted and a CSU Module or a Sync Spliltter is
already installed) or when the CSU Module/
Sync Splitter 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
for the CSU Module
and T1 Sync Splitter.
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/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. Begin by replacing the
CSU Module/T1 Sync Splitter 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/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
TN464F board is physically inserted and the CSU Module or the Sync Spliltter is
already installed) or when the CSU Module/Sync Splitter 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
for the CSU
Module/T1 Sync Splitter.
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/T1 Sync
Splitter.
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 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 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 UUCSS end-loopback/span-test
command.
