FAIL
A non-service-affecting CSU module/Sync Splitter audit failure was detected by
the UDS1 circuit pack. No ports should be affected. No immediate action is
required. These errors indicate that the CSU module/Sync Splitter hardware
may have a problem, and that it should be replaced when practical to avoid
further deterioration.
1400
FAIL
Echo Canceller function failed. This could be a hardware problem on the
TN464GP/TN2464BP:
1. Issue the busyout board command.
2. Issue the reset board command.
3. Issue the test board long command.
4. Issue the release board command.
5. If Test 1420 still fails, replace the TN464GP/TN2464BP.
1401
FAIL
Echo Canceller memory failed, this could be a hardware problem on the
TN464GP/TN2464BP:
1. Issue the busyout board command.
2. Issue the reset board command.
3. Issue the test board long command.
4. Issue the release busy board command.
5. If the test still fails, replace the TN464GP/TN2464BP.
PASS
DS1 signal is present and the physical link is healthy. In addition, no Integrated
CSU/Sync Splitter errors or echo cancellation errors are detected.

NO
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. 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 so, the board is shut down.
Reseating the board will re-initialize it.
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.
