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.
