Far CSU Loopback Test (#1213)
This test is destructive.
The Far CSU Loopback (R-LLB) Test causes a loopback at the far-end CSU and
tests all circuitry and facilities from the local TN464F DS1 board to the far-end
CSU.
3 FAIL The CPE Loopback Jack Test was not set up properly. The framed 3-in-24
test pattern, generated by the UDS1 Interface circuit pack and looped
back through the CPE Loopback Jack, could not be detected properly by
the UDS1 circuit pack.
1. Retry the
test ds1-loop PCSS cpe-loopback-jack-test-begin
command.
2. If the CPE Loopback test continues to fail, the problem could be with
the TN464F board, the CPE Loopback Jack equipment, or somewhere
in between. Run the
test ds1-loop PCSS ds1/csu-loopback-tests
command to see if the loopback tests closer to the TN464F board are
successful. If any of those loopback tests fail, follow the maintenance
strategy associated with those loopbacks. Otherwise, escalate the
problem.
PASS The CSJ Loopback test has successfully began executing. The test will
continue to run until the system technician enters the
test ds1-loop PCSS
end-loopback/span-test
command or the
release board PCSS
command.
0NO
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
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.
