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.

Description/ Recommendation
ABORT
System resources required for this test are not available.
1. Retry the command at 1-minute intervals a maximum of 5 times.

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.

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. The status health command can be used to determine if
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 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.
