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 passed.

Test
Result Description/Recommendation
ABORT Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals a maximum of 5 times.
1000 ABORT System resources required to run this test were not available. The
port may be busy with a valid call. Use the display port PCSSpp
command to determine the trunk group/member number of the port.
Use the status trunk command to determine the service state of the
port. If the service state indicates that the port is in use, then the port
is unavailable for certain tests. You must wait until the port is idle
before retesting.
1. If the port status is active but the port is not in use (no calls),
check the error log for error type 1025 (see the Error Log table
for a description of this error and required actions). The port may
be locked up.
2. If the port status is idle, retry the command at 1 minute intervals
for a maximum of 5 times.
3. If the test continues to abort, escalate the problem.
1002 ABORT The system could not allocate time slots for the test. The system may
be under heavy traffic conditions, or it may have time slots out of
service due to TDM-BUS errors. 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 and is not handling heavy
traffic and the port status is idle, retry the command at 1 minute
intervals for a maximum of 5 times.
