CPE Loopback Jack Test (#1212)
This test is destructive.
The CPE Loopback Jack (CLJ-LB) Test causes a loopbac k at the CPE Loopback
Jack and tests the buil ding wiring c onnection between the TN464F DS1 board
and the CPE Loopback Jac k.
The test is highly destructive and can only be initiated by a system technic ian
demanded

test ds1-loop UUCSS cpe-loopback-jack-test-begin

[number-of-bits bit-pattern]

command. The System technician has th e choice
of entering a loopbac k activation code o n the command line or using the default
code

0x47F

.
All trunks or ports on the UDS1 Interface c ircuit pack must b e busied out via the
system technician busyout board command before running the CPE Loopbac k
Jack Test.
The CPE Loopback Jack Test has the TN464F UDS1 Interface circuit pack
transmit a loopback ac tivation code to the CPE Loopbac k Jack, waits up to 10
PASS The RLB test executed successfully. The test pattern was transmitted and
received successfully over the connection from the TN464F DS1 board to the
far-edge of the 120A1 CSU Module or the 401A T1 Sync Splitter.

BOARD The test could not relate the internal ID to the port (no board). This could be
due to incorrect translations, no board is inserted, an incorrect board is
inserted, or an insane board is inserted.
1. Ensure that the board translations are correct. Execute the add ds1
UUCSS command to administer 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 is hyperactive. If this is the case, the board
is shut down. Reseating the board will re-initialize the board.
3. If the board was found to be correctly inserted in step 1, then issue the
busyout board command.
4. Issue the reset board command.
5. Issue the release busy board command.
6. Issue the test board long command.
This should re-establish the linkage between the internal ID and the port.
