UDS1-BD (UDS1 Interface Circuit Pack)

DS1 Board Loopback Test (#1209)
This test is destructive.
The DS1 Board Loopback (BLB) Test causes a loopback at the DS1 board edge
and tests DS1 board internal circuitry.
The test is destructive and can only be initiated by a system technician demanded
test ds1-loop UUCSS ds1/csu-loopback-tests command.
All trunks or ports on the UDS1 Interface circuit pack must be busied out using the
system technician busyout board command before running the BLB Test.

Result Description/Recommendation
ABORT Internal system error
1. Retry the command at 1-minute interval s a maximum of 5
times.
FAIL Internal system software error.
1. Enter the display ds1 UUCSS command to verify the
UDS1 Interface circuit pack translation.
PASS Translation data has been downloaded to the UDS1 Interface
circuit pack successfully.
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.
