Conference Circuit Test (#7)

One or more NPEs reside on each circuit pack with a TDM Bus interface. The

NPE controls port connectivity and gain, and provides conferencing functions on

a per-port basis. The Conference Circuit Test verifies that the NPE channel for

the port being tested can correctly perform the conferencing function. The NPE is

instructed to listen to several different tones and conference the tones together.

The resulting signal is then measured by a Tone Detector port. If the level of the

tone is within a certain range, the test passes.

1004 ABORT The port was seized by a valid call during the test and the test has been

aborted. You must wait until the port is idle (yellow LED if off) before

retesting.

1. Retry the command at one-minute intervals a maximum of five times.

2. If the test continues to abort and the port is not in use, escalate the

problem.

1020 ABORT The test did not run due to an already existing error on the specific port or a

more general circuit pack error.

1. Examine Error Log for existing errors against this port or the circuit

pack and attempt to diagnose the already existing error.

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.

1. Retry the command at one-minute intervals a maximum of five times.

2. If the test continues to abort, escalate the problem.

Any FAIL The NPE of the tested port was found to be transmitting in error. This

causes noisy and unreliable connections.

1. Replace the 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

the Error Log.
