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.
The test is destructive and can only be initiated by a system technician
demanded
test ds1-loop PCSS far-csu-loopback-test-begin
command.
All trunks or ports on the UDS1 Interface circuit pack must be busied out via the
system technician busyout board command before running the Far CSU
Loopback Test.
If the far-end CSU is not an AT&T 120A1 CSU Module, and the UDS1 is
administered for ami-zcs line coding, one’s density protection must be disabled
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.
