FAIL

UDS1 Interface circuit pack failed the CSU Equipment Loopback test.

1. Retry test ds1-loop location ds1/csu-loopback-tests.
2. If the ELB test continues to fail, then either the UDS1-BD 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. 

3. Replace the CSU module/T1 sync splitter and run test ds1-loop 

location ds1/csu-loopback-tests again.

4. If the ELB test continues to fail, replace the UDS1-BD board, and run 

test ds1-loop location ds1/csu-loopback-tests again.

5. 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.

 

PASS

The ELB test executed successfully. The test pattern was transmitted and 

received successfully over the connection from the DS1 board to the 

near-edge of the 120A1 CSU module or the 401A T1 sync splitter.

NO

BOARD

The test could not relate the internal ID to the port (no board). This could 
be due to incorrect translations, no board is inserted, an incorrect board is 
inserted, or an insane board is inserted.

1. Verify that the board’s translations are correct. Execute add ds1 

location to administer the UDS1 interface if it is not already 

administered.

2. If the board was already administered correctly, check the error log to 

determine whether the board is hyperactive. If so, the board was shut 
down. Reseating the board will re-initialize it.

3. If the board was found to be correctly inserted in step 1, enter 

busyout board location.

4. Enter reset board location.
5. Enter release board location.
6. Enter test board location long.

This should re-establish the linkage between the internal ID and the port.
