Conference Circuit Test (#7)
One or more Network Processing Elements (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 The test was aborted. 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.
1002 ABORT The test was aborted. 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.
