1302 FAIL Attempting to use the 120A1 CSU Module with a TN767E circuit
pack that is configured for 32-channel (2.048 Mbps) operation.
The CSU Module only works with a DS1 board configured for
24-channel (1.544 Mbps) operation in the United States of
America.
1. If the 120A1 CSU Module is to be used, physically remove
the TN767E circuit pack and reconfigure for 24-channel
(1.544 Mbps) operation.
2. Reinsert the circuit pack and run the test again.
1303 FAIL The DS1 circuit pack Suffix is incorrect for CSU Module/T1 Sync
Splitter administration. The Near-End CSU Type field on the add
ds1 form has been administered as integrated but the DS1 circuit
pack is not a TN767E or later suffix DS1 board.
1. If the CSU Module or the T1 Sync Splitter is to be used, and
the Near-End CSU Type field is set to integrated to allow for
CSU Module/T1 Sync Splitter administration, remove the
circuit pack and replace it with a TN767E or later suffix board.
Otherwise use the change ds1 command to change the
Near-End CSU Type field to other.
1310 FAIL The DS1 Board Loopback (BLB) demand test (#1209) failed.
1. Repeat the test using the test ds1-loop UUCSS
ds1/csu-loopback-tests command.
2. If the BLB test continues to fail, then replace the TN767E
circuit pack.
3. Run this test again.
