UDS1-BD (UDS1 Interface Circuit Pack)
Issue 1 June 2005 2463
3 FAIL The Far CSU Loopback test was not set up properly. The framed 3-in-24
test pattern, generated by the UDS1 Interface circuit pack and looped
back through the far-end CSU, could not be detected properly by the
UDS1 circuit pack.
1. Retry test ds1-loop location
far-csu-loopback-test-begin.
2. If the Far CSU Loopback test continues to fail with this Error Code,
the problem could be with the UDS1-BD board, the far-end CSU
equipment, or somewhere in between. Run test ds1-loop
location cpe-loopback-jack-test-begin to see if the CPE
Loop-Back Jack test which is closer to the UDS1-BD board is
successful. (If a CPE Loop-back Jack device is not being used, run
test ds1-loop location ds1/csu-loopback-tests to see if
these even closer loop-back tests succeed). If the closer loop-back
test fails, follow the maintenance strategy associated with that
loopback.
PASS The Far CSU Loopback test has successfully began executing. The test
will continue to run until the system technician enters test ds1-loop
location end-loopback/span-test or release board
location.

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. Verify that the board’s translations are correct. Execute add ds1
location 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 so, the board was shut
down. Reseating the board will re-initialize it.
3. If the board was found to be correctly inserted in step 1, enter
busyout board location.
4. Enter reset board location.
5. Enter release board location.
6. Enter test board location long.
This should re-establish the linkage between the internal ID and the port.
