Conference Circuit Test (#7)
One or more Network Processing Elements (NPEs) reside on each circuit pack
with a TDM Bus interface. (The TN464C UDS1 circuit pack has one
SCOTCH-NPE chip instead of several NPE chips). The NPE controls port
connectivity and gain, and it 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 to 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 one 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
access-endpoint <extension> 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 access-endpoint <extension> command to
determine when the port is available for testing. The port is
available when it is in the in-service/idle state.
1. Retry the command at one minute intervals a maximum of
5 times.
2. If the test continues to abort, and if the port is not in use,
escalate the problem.
1020 ABORT The test did not run due either to a previously existing error on
the specific port or to a more general circuit pack error.
1. Examine the Error Log for existing errors against this port
or circuit pack, and attempt to diagnose the previously
existing error.
