Conference Circuit Test (#7)
Note:
Note: S8500 / G700: This test aborts with Error Code 1412 on the G700.
One or more Network Processing Elements (NPEs) reside on each circuit pack with a TDM-bus
interface. (The TN464 UDS1 circuit pack has one SCOTCH-NPE chip instead of several NPE
chips). 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
ABRT System resources required for this test are not available.
1. Retry the command at 1-minute intervals up to 5 times.
1000 ABRT System resources required to run this test were not available. The
port may be busy with a valid call.
1. Use display port location 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.
Wait until the port is idle before retesting.
2. If the port status is active but the port is idle (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.
3. If the port status is idle, retry the command at 1-minute intervals
up to 5 times.
1002 ABRT 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. Use status health to
determine if the system is experiencing heavy traffic.
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 up to 5 times.
