Looparound and Conference Test (#33)

This test checks the reflective loop around and conference capabilities of an auxiliary trunk port
circuit. The test uses 404-Hz, 1004-Hz, and 2804-Hz tones. Each tone is separately
transmitted through the loop and checked. All of these tests are performed on-board.

Any

FAIL

The Network Processing Element (NPE) of the tested port was found to be
transmitting in error. This will cause noisy and unreliable connections. This
problem may be caused by defective Tone Detectors.

1. Test every Tone-Clock circuit pack, and resolve any errors on these

circuit packs before any action is taken on the auxiliary trunk circuit
pack. Then, repeat the test.

2. If the test fails again, replace the auxiliary trunk circuit pack.

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.

ABRT

System resources required to run this test are not available. The port may
be busy with a valid call.

1. Use display port location to determine the trunk group/member

number of the port. Use status trunk to determine the service

state of the port. If the port is active, wait until it is idle.

2. Retry the command at 1-minute intervals up to 5 times.
