DS1-BD (DS1 Interface Circuit Pack)
Issue 1 June 2005 1041
3 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
far-csu-loopback-test-begin.
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
board
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.
