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 fa cilities from the local TN767E 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 DS1 Interface circuit pac k and looped back through
the CPE Loopback Jack, could not be detected p roperly by the DS1 circuit
pack.
1. Retry
t
est 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
t
est ds1-loop UUCSS
end-loopback/span-test command or the release board UUCSS 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. 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 wa s already administered correctly, check the error lo g 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 c orrectly 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.
