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 TN464F 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 PCSS 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 lin e or using the default
code (0x47F).
All trunks or ports on the UDS1 Interface circuit pack must be busied out via the
system technician busyout board command before running the CSJ Loopback
Test.
The CPE Loopback Test has the TN464F UDS1 Interface circuit pack transmit a
loopback activation code to the CPE Loopback Jack, waits up t o 10 seconds for
return of the code to verify the loopback 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
0NO
BOARD The test could not relate the internal ID to the port (no boa rd). T his coul d 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
PCSS 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.
