CSU Repeater Loopback Test (#1211)
This test is destructive.
The CSU Repeater Loopback (RLB) Test causes a loopback at the far-edge of
the local AT&T 120A1 CSU Module and tests the connection from the TN464F
DS1 board to and including the CSU Module circuitry. This test will only be
performed if the AT&T 120A1 CSU Module is present, administered, and
connected to a 1.544 Mbps TN464F DS1 circuit pack on the back of the port
carrier.

1. Ensure that the board translations are correct.
Execute the

the UDS1 interface if it is not already administered.
2. If the board was already administered correctly,
check the error log to determine whether the board
