FAIL UDS1 Interface circuit pack failed the CSU Equipment Loopbac k Test.
1. Retry the
test ds1-loop UUCSS ds1/csu-loopback-tests
command.
2. If the ELB test continues to fail, then either the TN464F 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 TN464F 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 TN464F DS1 board to the
near-edge of the 120A1 CSU Module or the 401A T1 Sync Splitter.
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.
