Loop Around and Conference Circuit Test (#33)
This test checks the reflective and non-reflective loop around and conference
capabilities of a DID port circuit. The test that uses 404-Hz, 1004-Hz, and
2804-Hz tones is an on-board test only. Each tone is separately transmitted to
and from the port (loop around within the port) and verified.
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 trunk administration Test field. (This also disables the port
diagnostic test.

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.
