1321 FAIL DTE LOS (loss of signal) was detected between the TN767E DS1 board
and the 120A1 CSU module or the T1 sync splitter. Either the TN767E
board, the 120A1 CSU module/T1 sync splitter, or the I/O cable between
the backplane and the 120A1 CSU module or the 401A T1 sync splitter (or
any combination thereof) has failed. Attempt to isolate the problem to one
of these areas.
1. Replace the CSU module/T1 sync splitter, and run the test again.
2. If the test continues to fail with this error code, then replace the
TN767E board, and run the test again.
3. 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.
1322 FAIL No 5-Volt power detected from the TN767E circuit pack to the 120A1 CSU
module/T1 sync splitter. Problem is 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.
