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.
This test may fail due to noise induced by adjacent electric power lines.
Customers having this problem should resolve it with their local power company.
To temporarily alleviate the alarm caused by the failure of this test, the test may
be disabled from the trunk administration Test field.
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.
