Loss of Signal Alarm Inquiry Test (#138)
1301 FAIL The 120A CSU module or the 401A T1 sync splitter, or the 402A or 403A
E1 synchronization splitter is not expected.
The 120A CSU module or the 401A T1 sync splitter is not expected: The
120A CSU module/T1 sync splitter is physically connected to the DS1/
UDS1 board on the back of the port carrier, but the Near-End CSU Type
field on the add ds1 screen has not been administered as integrated.
1. If the 120A CSU module/T1 sync splitter is to be used, use change
ds1 to set the Near-End CSU Type field to integrated. Otherwise,
physically remove the 120A CSU module/T1 sync splitter from the
back of the port carrier.
2. Run the test again.
The 402A or 403A E1 synchronization splitter is not expected: The 402A
or 403A E1 synchronization splitter is physically connected to the DS1/
UDS1 board on the back of the port carrier, but the E1 Sync-Splitter?
field on the add ds1 screen has not been administered as y.
1. If the 402A or 403A E1 synchronization splitter is to be used, use
change ds1 to change the E1 Sync-Splitter field to y. Otherwise,
physically remove the 402A or 403A E1 synchronization splitter from
the back of the port carrier.
2. Run the test again.
1302 FAIL Attempting to use the 120A CSU module with a DS1/UDS1 circuit pack
that is configured for 32-channel (2.048-Mbps) operation. The CSU
module only works with a DS1/UDS1 board configured for 24-channel
(1.544-Mbps) operation in the United States.
1. If the 120A CSU module is to be used, physically remove the DS1/
UDS1 circuit pack and reconfigure it for 24-channel (1.544-Mbps)
operation.
2. Reinsert the circuit pack and run the test again.
