1320 FAIL A 120A1 CSU module hardware failure or an ICSU serial interface audit
failure was detected by the TN464F UDS1 circuit pack.
1. Replace the CSU module, and then run the test again.
2. If the test continues to fail with this error code, replace the TN464F and
run the test again.
3. If the test continues to fail with this error code, then the problem could
be in the I/O cable between the backplane and the CSU module.
1321 FAIL DTE LOS (loss of signal) was detected between the TN464F UDS1 board
and the 120A1 CSU Module. Either the TN464F board, the 120A1 CSU
Module, or the I/O cable between the backplane and the CSU module (or
any combination thereof) has failed. Attempt to isolate the problem to one
of these areas.
1. Replace the CSU Module and run the test again.
2. If the test continues to fail with this error code, then replace the
TN464F 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 CSU module.
1322 FAIL No 5 volts power detected from the TN464F circuit pack to the 120A1 CSU
Module. Problem probably due to an open fuse on the DS1 board or a
faulty ICSU.
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 and run the test again.
2. Remove the TN464F 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
TN464F 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.
1323 FAIL A service affecting CSU Module audit failure was detected by the TN464F
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 120A1 CSU Module.
