Internal Loop-Around Test (#135)
This test is destructive.
The Internal Looparound test is run by looping the transmitted DS1 bit stream
back into the DS1’s board receiver. The loop occurs just before the DS1 facility
interface. The test is highly destructive and can only be initiated by a
technician-demanded reset board UUCSS command.
1015
ABORT
Port is not out-of-service.
1. Busyout the circuit pack.
2. Execute the command again.
2100
ABORT
System resources required for this test are not available.
1. Retry the command at 1-minute intervals up to 5 times.
1
FAIL
The circuit pack failed to reset.
2
FAIL
The circuit pack failed to restart.
1. Execute the command again.
2. If the problem persists, escalate this problem.
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. Verify that the board’s translations are correct. Use the add ds1 UUCSS
command to administer the DS1 interface if it is not already administered.
2. If 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, 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.
