CPE Loopback Jack Test (#1212)
This test is destructive.
The CPE Loopback Jack (CLJ-LB) Test causes a loopback at the CPE Loopback
Jack and tests the building wiring connection between the TN767E DS1 board
and the CPE Loopback Jack.
The test is highly destructive and can only be initiated by a system technician
demanded test ds1-loop UUCSS cpe-loopback-jack-test-begin
[number-of-bits bit-pattern] command. The System technician has the choice of
entering a loopback activation code on the command line or using the default
code (0x47F).
All trunks or ports on the DS1 Interface circuit pack must be busied out via the
system technician busyout board command before running the CPE Loopback
Jack Test.

NO
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. Check to ensure that the board translations are correct. Use the add ds1
UUCSS command to administer the DS1 interface if it is not already
administered.
2. If board was already administered correctly, check the error log to
determine if 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, 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 link between the internal ID and the port.
