FAIL

The Integrated CSU (I-CSU) Module Repeater Loopback (RLB) test 
(#1211) 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 120A1 CSU 
module/T1 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 
location ds1/csu-loopback-tests.

1. Execute test ds1-loop location ds1/csu-loopback-tests.
2. If the RLB test continues to fail, replace the CSU module/T1 sync 

splitter.

3. Run this test again.

FAIL

The TN767E circuit pack could not deactivate a CPE loop-back jack loop 
back.

1. Execute test ds1-loop location end-loopback/

span-test.

2. If the attempt to deactivate the CPE loop-back jack is not successful, 

check the cabling and investigate the problem at the CPE loop-back 
jack.

3. Run the test again.

FAIL

The TN767E circuit pack could not deactivate a far-end CSU loop-back.

1. Execute test ds1-loop location end-loopback/

span-test.

FAIL

A CSU module/T1 sync splitter hardware failure or an ICSU/T1 sync 
splitter serial interface audit failure was detected by the TN767E DS1 
circuit pack.

1. Replace the CSU module/T1 sync splitter, and then run the test again.

2. If the test continues to fail with this error code, replace the TN767E 

and run the test again.

3. If the test continues to fail with this error code, the problem could be in 

the I/O cable between the backplane and the CSU module/T1 sync 
splitter.
