FAIL

The far CSU Loopback test was not set up properly. The framed 3-in-24 
test pattern, generated by the DS1 Interface circuit pack and looped back 
through the far-end CSU, could not be detected by the DS1 circuit pack.

1. Retry  test ds1-loop location 

2. If the Far CSU Loopback test continues to fail with this error code, the 

problem could be with the TN767E board, the far-end CSU equipment, 
or somewhere in between. Run test ds1-loop location 
cpe-loopback-jack-test-begin to see if the CPE Loopback Jack 

test that is closer to the TN767E board is successful. 

If a CPE loop-back jack device is not being used, run test ds1-loop 
location ds1/csu-loopback-tests to see if the closer loop-back 

tests succeed. If the closer loop-back test fails, follow the maintenance 
strategy associated with that loop back

 

PASS

The Far CSU Loopback test has successfully began executing. The test runs 

until the system technician enters test ds1-loop location 

end-loopback/span-test or the release board location.

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 busyout 

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.
