3 FAIL The CPE Loopback Jack Test was not set up properly. The framed
3-in-24 test pattern, generated by the DS1 Interface circuit pack
and looped back through the CPE Loopback Jack, could not be
detected properly by the DS1 circuit pack.
1. Retry test ds1-loop UUCSS cpe-loopback-jack-test-begin.
2. If the CPE Loopback test continues to fail, the problem could
be with the TN767E board, the CPE Loopback Jack
equipment, or somewhere in between. Run test ds1-loop
UUCSS ds1/csu-loopback-tests to see if the loopback tests
closer to the TN767E board are successful. If any of those
loopback tests fail, follow the maintenance strategy associated
with those loopbacks.
PASS The CPE Loopback Jack test has successfully began executing.
The test will continue to run until the system technician enters the
test ds1-loop UUCSS end-loopback/span-test command or the
release board UUCSS command.
0 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.
