Conference Circuit Test (#7)
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.

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 are not available.
The port may be in use on a valid call. Use the status station
or status trunk command to determine when the port is
available for testing.
1004 ABORT The port has been seized by a user for a valid call. Use the
status station or status trunk command to determine when
the port is available for testing.
1. Retry the command at 1-minute intervals a maximum of 5
times.
2. If the test continues to abort, and the port is not in use,
escalate the problem.
1018 ABORT Test disabled via administration. This only applies to analog
stations.
1. To enable test, set the Test field on the station
administration screen for the particular analog station
being tested to ‘‘y.’’ Use the change station extension
command.
1020 ABORT The test did not run due to a previously existing error on the
specific port or a more general circuit pack error.
1. Examine Error Log for existing errors against this port or
the circuit pack and attempt to diagnose the previously
existing error.
