FAIL

The UDS1 circuit pack could not deactivate a CPE Loop-Back Jack 
loopback.

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 UDS1 circuit pack could not deactivate a far-end CSU loopback.

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

1320

FAIL

Either a CSU module/Sync Splitter hardware failure or an ICSU/Sync 

Splitter serial-interface audit failure was detected by the UDS1 circuit pack.

5. Replace the CSU module/Sync Splitter, and then run the test again.

6. If the test continues to fail with this Error Code, replace the UDS1-BD 

circuit pack, and run the test again.

7. If the test continues to fail with this Error Code, then the problem 

could be in the I/O cable between the backplane and the CSU 
module/Sync Splitter.

1321

FAIL

DTE LOS (loss of signal) was detected between the UDS1 board and the 

CSU module or the Sync Splitter. Either the UDS1 board, the CSU module/

Sync Splitter, or the I/O cable between the backplane and the CSU module/

Sync Splitter (or any combination thereof) has failed. Attempt to isolate the 

problem to one of these areas.

8. Replace the CSU module/Sync Splitter, and run the test again.

9. If the test continues to fail with this Error Code, then replace the 

UDS1-BD board, and run the test again.

10. 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/Sync 
Splitter.
