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 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 display port
UUCSSpp to determine the trunk group/member number of
the port. Use status trunk 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.
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. 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.
