DS1-BD (DS1 Interface Circuit Pack)
Issue 4 May 2002
10-637555-233-123
1322 FAIL No 5 volts power detected from the TN767E circuit pack to the
120A1 CSU Module/T1 Sync Splitter. Problem probably due to an
open fuse on the DS1 board or a faulty ICSU/T1 Sync Splitter.
NOTE Do not swap DS1 boards as this may open the fuse on the
new board.
1. Remove the TN767E from the system and reinsert.
2. Run the test again once the board has finished its reset.
3. If the test continues to fail with this error code, then replace
the CSU Module/T1 Sync Splitter and run the test again.
4. If the test continues to fail with this error code, the problem
could be in the I/O cable between the backplane and the
120A1 CSU Module or the 401A T1 Sync Splitter.
5. If the test continues to fail with this error code, escalate this
problem.
1323 FAIL A service-affecting CSU Module/T1 Sync Splitter audit failure was
detected by the TN767E DS1 circuit pack. All administered ports
on the DS1 circuit pack are affected and maintenance software
will place the ports into the out-of-service state.
1. Replace the 120A1 CSU Module/T1 Sync Splitter.
1324 FAIL A non-service-affecting CSU Module/T1 Sync Splitter audit failure
was detected by the TN767E DS1 circuit pack. No ports should
be affected. No immediate action is required. These errors
indicate that the CSU Module/T1 Sync Splitter hardware may
have a problem, and that it should be replaced when practical to
avoid further deterioration.
