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 Sp litte r.
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 prob lem to one of these areas. Begi n 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 loopbac k .
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.
