Loop Around and Conference Circuit Test (#33)
This test checks the reflective loop around, and conference capabilities of a tie
trunk port circuit. The test uses 404-Hz, 1004-Hz, and 2804-Hz tones. This is an
on-board test only, and each tone is transmitted through the loop and checked
upon return.
2000 ABORT Response to the test request was not received within the allowable time
period.
2100 ABORT Could not allocate the necessary system resources to run this test. This
could be due to a failure to seize the port.
1. Retry the command at 1-minute intervals a maximum of 5 times.
Any FAIL This test can fail due to on-board or off-board problems. Off-board
problems of concern include TDM-BUS faults and faults associated with
the tone detectors/tone generators. Clear all off-board problems before
replacing the board. Keep in mind that a TDM-BUS problem is usually the
result of a faulty board connected to the backplane or bent pins on the
backplane.
1. Look for TDM-BUS errors in the error log. If present, refer to the
TDM-BUS Maintenance documentation.
2. Look for TONE-BD and/or TONE-PT errors in the error log. If present,
refer to the TONE-BD Maintenance documentation and the TONE-PT
Maintenance documentation.
3. Test the board when the faults from steps 1 and 2 are cleared. Replace
the board only if the test fails.
PASS The port is correctly using its allocated time slots. User-reported troubles
on this port should be investigated using other port tests and examining
station, trunk or external wiring.
0NO
BOARD
The test could not relate the internal ID to the port (no board).
1. Check to ensure that the board translations are correct. Translate the
board, if necessary.
2. Issue the busyout board command.
3. Issue the reset board command.
4. Issue the release busy board command.
5. Issue the test board command. This should re-establish the linkage
between the internal ID and the port.
