FAIL

DS1 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 TN767E board, the 

CSU module/T1 sync splitter, or the I/O cable between the backplane 
and the 120A1 CSU module or the 401A T1 sync splitter (or any 
combination thereof) has failed. Attempt to isolate the problem to one 
of these areas. Replace the CSU module/T1 sync splitter, and run 
test ds1-loop location ds1/csu-loopback-tests again.

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 120A1 CSU module or the 401A T1 
sync splitter.

 

PASS

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

received successfully over the connection from the TN767E DS1 board to 

the near-edge of the 120A1 CSU module/T1 sync splitter.

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. Use add ds1 

location to administer the DS1 interface if it is not already 

administered.

2. If 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 

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

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