CSU Equipment Loopback Test (#1210)
This test is destructive.
The CSU Equipment Loopback (ELB) Test causes a loopback at the near-edge
of the local AT&T 120A1 CSU Module and tests the connection from the TN464F
FAIL UDS1 Interface circuit pack failed the DS1 Board
Loopback Test.
1. Retry the
test ds1-loop PCSS
ds1/csu-loopback-tests
command.
2. If the BLB test continues to fail, then replace the
UDS1 circuit pack.
PASS The BLB test executed successfully. The test pattern
was transmitted and received successfully up to the
TN464F DS1 board edge.
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.
