CSU Repeater Loopback Test (#1211)
The CSU RLB (Repeater Loopback) test causes a loopback at the far-edge of the local 120A
CSU module or T1 sync splitter, and tests the connection from the DS1 board to and including
the CSU module/T1 sync splitter circuitry. The test runs only if the 120A CSU module/T1 sync
splitter is present, administered, and connected to a 1.544-Mbps DS1 circuit pack on the back
of the port carrier.
The test is destructive and can only be initiated by entering the command
test ds1-loop location ds1/csu-loopback-test.
Enter busyout board to busy out all trunks or ports on the DS1 Interface circuit pack before
running the RLB test.
When the RLB test is initiated, maintenance software sends a message to the DS1 Interface
circuit pack to start the test. The board sets up the RLB loopback, transmits a test pattern, and
verifies that the pattern is received unaltered through the loopback. If the transmitted and
received pattern is different, the test fails.
The DS1 circuit pack hardware applies a DC current while the test is running in order to detect
any broken wires that may not be detected by the loopback pattern.
When the test is complete, use release board to restore all trunks or ports on the DS1
Interface circuit pack to the in-service state
This test is run on the DS1-BD (DS1 Interface Circuit Pack) and UDS1-BD (UDS1 Interface
Circuit Pack) maintenance objects.

1. Enter test ds1-loop location ds1/csu-loopback-tests
at 1-minute intervals up to 5 times.
1005 ABORT CSU Repeater Loopback test cot be executed in the current
configuration.
1. Enter change ds1 location and set the Near-End CSU Type
field on the DS1 circuit pack administration screen to integrated,
and/or set the Bit Rate field to 1.544 if the board is to be used in a
24-chel configuration.
2. Enter test ds1-loop location ds1/csu-loopback-tests.
1015 ABORT Ports on the DS1 Interface circuit pack have not been busied out.
1. Enter busyout board location to put all trunks or ports of the
DS1 Interface circuit pack into the out-of-service state.
2. Retry the command.
