Table 543. TEST #1213 Far CSU Loopback Test — Continued
Error Test
Code Result
3 FAIL The Far CSU Loopback Test was not set up properly. The framed 3-in-24 test
pattern, generated by the UDS1 Interface circuit pack and looped back
through the far-end CSU, could not be detected properly by the UDS1 circuit
pack.
PASS The Far CSU Loopback test has successfully began executing. The test will
continue to run until the system technician enters the test ds1-loop UUCSS
end-loopback/span-test command or the release board UUCSS command.
0 NO The test could not relate the internal ID to the port (no board). This could be
BOARD due to incorrect translations, no board is inserted, an incorrect board is
inserted, or an insane board is inserted.
This should re-establish the linkage between the internal ID and the port.

Description/ Recommendation
1. Retry the test ds1-loop UUCSS far-csu-loopback-test-begin
command.
2. If the Far CSU Loopback test continues to fail with this error code, the
problem could be with the UDS1-BD board, the far-end CSU equipment,
or somewhere in between. Run the test ds1-loop UUCSS
cpe-loopback-jack-test-begin command to see if the CPE Loopback
Jack test which is closer to the UDS1-BD board is successful. (If a CPE
Loopback Jack device is not being used, then run the test ds1-loop
UUCSS ds1/csu-loopback-tests command to see if these even closer
loopback tests succeed). If the closer loopback test fails, follow the
maintenance strategy associated with that loopback.
1. Ensure that the board translations are correct. Execute the add ds1
UUCSS command 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 this is the case, the board
is shut down. Reseating the board will re-initialize the board.
3. If the board was found to be correctly inserted in step 1, then issue the
busyout board command.
4. Issue the reset board command.
5. Issue the release busy board command.
6. Issue the test board long command.
