Internal Looparound Test (#135)
This test is destructive.
The Internal Looparound Test is run by looping the transmitted DS1 bit stream
back into the UDS1’s board receiver. The loop occurs just before the DS1 facility
interface. The test is highly destructive and can only be initiated by a system
technician-demanded reset board UUCSS 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 Internal
Looparound Test. When the Internal Looparound Test is initiated, maintenance
software sends appropriate messages to the UDS1 Interface circuit pack to start
the test. The test uses the Tone Generator and Tone Detector to exercise a bit

FAIL
The circuit pack failed to restart.
1. Execute the reset board command again.
2. If the problem persists, replace the circuit pack.
PASS
The circuit pack initializes correctly.
1. Run the Short Test Sequence.
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.
