Table 227. TEST #138 Loss of Signal Alarm Inquiry Test — Continued
Error Test
Code Result
1303 FAIL The DS1 circuit pack Suffix is incorrect for CSU Module/T1 Sync Splitter
administration. The Near-End CSU Type field on the add ds1 form has been
administered as integrated but the DS1 circuit pack is not a TN767E or later
suffix DS1 board.
1310 FAIL The DS1 Board Loopback (BLB) demand test (#1209) failed.
1311 FAIL The Integrated CSU (I-CSU) Module Equipment Loopback (ELB) test (#1210)
failed. This test is executed during ICSU/T1 Sync Splitter power-up/reset (the
TN767E board is physically inserted and the CSU Module/T1 Sync Splitter is
already installed) or when the 120A CSU Module/T1 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.

Description/ Recommendation
1. If the CSU Module or the T1 Sync Splitter is to be used, and the
Near-End CSU Type field is set to integrated to allow for CSU Module/T1
Sync Splitter administration, remove the circuit pack and replace it with a
TN767E or later suffix board. Otherwise use the change ds1 command to
change the Near-End CSU Type field to other.
1. Repeat the test using the test ds1-loop UUCSS ds1/csu-loopback-tests
command.
2. If the BLB test continues to fail, then replace the TN767E circuit pack.
3. Run this test again.
1. Execute test ds1-loop UUCSS ds1/csu-loopback-tests.
2. If the ELB test continues to fail, then either the TN767E 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 TN767E board and run
test ds1-loop UUCSS ds1/csu-loopback-tests 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.
