FAIL
UDS1 Interface circuit pack failed the CSU Equipment
Loopback Test.
1. Retry the test ds1-loop UUCSS ds1/csu-loopback-tests
command.
2. If the ELB test continues to fail, then either the UDS1-BD
board, the CSU Module/T1 Sync Splitter, or the I/O cable
between the backplane and the CSU module/T1 Sync
Splitter (or any combination thereof) has failed. Attempt to
isolate the problem to one of these areas. Begin by
replacing the CSU Module/T1 Sync Splitter and running the
test ds1-loop UUCSS ds1/csu-loopback-tests command
again.
3. If the ELB test continues to fail, then replace the UDS1-BD
board and run the test ds1-loop UUCSS
ds1/csu-loopback-tests command again.
4. If the ELB test continues to fail, the problem could be in the
I/O cable between the backplane and the CSU module/T1
Sync Splitter.
PASS
The ELB test executed successfully. The test pattern was
transmitted and received successfully over the connection from
the DS1 board to the near-edge of the 120A1 CSU Module or
the 401A T1 Sync Splitter.
0
NO
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.
