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 TN464F DS1 board to the far-end
CSU.
The test is destructive and c an only be initiated by a system technician
demanded

test ds1-loop UUCSS far-csu-loopb ack-test-begin

command.
All trunks or ports on the UDS1 Interface c ircuit pack must b e busied out via the
system technician busyout board command before running the Far CSU
Loopback Test.
If the far-end CSU is not an Lucent 120A1 CSU Module, and the DS1 is
administered for ami-zcs line c oding, one’s d ensity protection must be d isabled
on the CSU during the test due to the larg e number of zero’s in the 3-in-24 test
pattern.
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.
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
UUCSS 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.
