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.
1. Retry the
test ds1-loop PCSS 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 TN464F board, the far-end CSU equipment,
or somewhere in between. Run the
test ds1-loop PCSS
cpe-loopback-jack-test-begin
command to see if the CPE Loopback
Jack test which is closer to the TN464F board is successful. (If a CPE
Loopback Jack device is not being used, then run the
test ds1-loop
PCSS 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. Otherwise,
escalate the problem.
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 PCSS
end-loopback/span-test
command or the
release board PCSS
command.
0NO
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. Ensure that the board translations are correct. Execute the add ds1
PCSS 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.
This should re-establish the linkage between the internal ID and the port.
