1310 FAIL The DS1 Board Loopback (BLB) demand test (#1209) failed.
1. Repeat the test using test ds1-loop location ds1/
csu-loopback-tests.
2. If the BLB test continues to fail, then replace the TN767E circuit pack.
3. Run this test again.
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 test ds1-loop location
ds1/csu-loopback-tests.
1. Execute test ds1-loop location ds1/csu-loopback-tests.
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.
2. Replace the CSU module/T1 sync splitter and run test ds1-loop
location ds1/csu-loopback-tests.
3. If the ELB test continues to fail, then replace the TN767E board and
run test ds1-loop location 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.
