UDS1-BD (UDS1 Interface Circuit Pack)
Table 530. TEST #138 Loss of Signal Alarm Inquiry Test — Continued
Error Test
Code Result
1320 FAIL A CSU Module/Sync Splitter hardware failure, or an ICSU/Sync Splitter serial
interface audit failure was detected by the UDS1 circuit pack.
1321 FAIL DTE LOS (loss of signal) was detected between the UDS1 board and the
CSU Module or the Sync Splitter. Either the UDS1 board, the CSU
Module/Sync Splitter, or the I/O cable between the backplane and the CSU
module/Sync Splitter (or any combination thereof) has failed. Attempt to
isolate the problem to one of these areas.
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.
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.

Description/ Recommendation
1. Replace the CSU module/Sync Splitter, and then run the test again.
2. If the test continues to fail with this error code, replace the UDS1-BD
circuit pack 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/Sync
Splitter.
1. Replace the CSU Module/Sync Splitter and run the test again.
2. If the test continues to fail with this error code, then replace the
UDS1-BD 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/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.
1. Replace the CSU Module or the Sync Splitter.
