CPE Loopback Jack Test (#1212)
This test is destructive.
The CPE Loopback Jack (CLJ-LB) test causes a loop back at the CPE loop-back jack and tests
the building wiring connection between the TN767E DS1 board and the CPE loop-back jack.
The test is highly destructive and can only be initiated by a technician-demanded test
ds1-loop location cpe-loopback-jack-test-begin [number-of-bits
bit-pattern]. The system technician can either enter a loop-back activation code on the
command line or use the default code (0x47F).
Use busyout board to busy out all trunks or ports on the DS1 Interface circuit pack before
running the CPE Loopback Jack test.
The CPE Loopback Jack test has the TN767E DS1 Interface circuit pack transmit a loop-back
activation code to the CPE loop-back jack, waits up to 10 seconds for return of the code to verify
the loop back has been established, transmits a framed 3-in-24 test pattern, begins counting bit
errors in the received test pattern, and returns a PASS result to indicate that the pattern was
successfully sent. If the loop back is not established within the 10 seconds, the test returns
FAIL.

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. Verify that the board’s translations are correct. Use add ds1
location to administer the DS1 interface if it is not already
administered.
2. If board was already administered correctly, check the error log to
determine whether the board is hyperactive. If so, the board was shut
down. Reseating the board will re-initialize it.
3. If the board was found to be correctly inserted in step 1, enter busyout
board
4. Enter reset board
5. Enter release board
6. Enter test board long
This should re-establish the link between the internal ID and the port.
