Table 240. TEST #1213 Far CSU Loopback Test — Continued
Error Test
Code Result
2 FAIL The far CSU Loopback Test was not set up properly. The DS1 Interface
circuit pack could not put the far-end CSU into loopback mode.
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.
PASS The Far CSU Loopback test has successfully began executing. The test will
continue to run until the system technician enters test ds1-loop UUCSS
end-loopback/span-test or the release board UUCSS.
0 NO The test could not relate the internal ID to the port (no board).
BOARD
This could be due to incorrect translations, no board is inserted, an incorrect
board is inserted, or an insane board is inserted.
This should re-establish the link between the internal ID and the port.

Description/ Recommendation
1. Retry test ds1-loop UUCSS 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 UUCSS
cpe-loopback-jack-test-begin to see if the CPE Loopback Jack test
which is closer to the TN767E board is successful. (If a CPE Loopback
Jack device is not being used, then run test ds1-loop UUCSS
ds1/csu-loopback-tests to see if these even closer loopback tests
succeed). If the closer loopback test fails, follow the maintenance
strategy associated with that loopback
1. Check to ensure that the board translations are correct. Use the add ds1
UUCSS command to administer the DS1 interface if it is not already
administered.
2. If board was already administered correctly, check the error log to
determine if 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, 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.
