555-233-123 10-1872 Issue 4 May 2002
1322 FAIL No 5 volts power detected from the UDS1 circuit pack to the CSU
Module or the Sync Splitter. Problem is probably due to an open
fuse on the DS1 board or a faulty ICSU/Sync Splitter.
NOTE:
Do not immediately swap DS1 boards as this may blow the
fuse on the new board.
1. If the test continues to fail with this error code, then replace
the CSU Module/Sync Splitter and run the test again.
2. Remove the UDS1 from the system and reinsert.
3. Run the test again once the board has finished its reset.
4. If the test continues to fail with this error code, then replace
the UDS1-BD board and run the test again.
5. If the test continues to fail with this error code, the problem
could be in the I/O cable between the backplane and the CSU
module/Sync Splitter.
1323 FAIL A service-affecting CSU Module/Sync Splitter audit failure was
detected by the UDS1 circuit pack. All administered ports on the
UDS1 circuit pack are affected and maintenance software will
place the ports into the out-of-service state.
1. Replace the CSU Module or the Sync Splitter.
1324 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 test board long command.
3. Issue the release board command.
4. If Test 1420 still fails, replace the TN464GP/TN2464BP.
