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.

Result Description/ Recommendation

ABORT System resources required for this test are not available.

1. Retry the command at one-minute intervals a

maximum of five times.

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

1000 ABORT System resources required to run this test are not

available. The port may be in use on a valid call. Use the

status station or status trunk command to determine

when the port is available for testing.

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.

1002 ABORT The test was aborted because the system could not

allocate time slots for the test. The system might be

under heavy traffic conditions, or it might have time slots

out of service due to TDM-BUS errors. (The status

health command may be used to determine whether the

system is experiencing heavy traffic.) Refer to the

TDM-BUS (TDM bus) Maintenance documentation to

diagnose any active TDM-BUS errors.

1. If the system has no TDM-BUS errors, is not

handling heavy traffic, and the port status is idle,

retry the command at 1-minute intervals for a

maximum of 5 times.

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