Conference Circuit Test (#7)
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.

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.
under heavy traffic conditions or it may have time slots out-of-service due to
TDM-BUS errors.
1. Resolve TDM-BUS errors, if any.
2. If the system is not handling heavy traffic, retry the command at
1-minute intervals a maximum of 5 times.
1003
ABORT
The system could not allocate a tone receiver for the test. The system may
be oversized for the number of tone detectors present, or some tone
detectors may be out-of-service.
be oversized for the number of tone detectors present, or some tone
detectors may be out-of-service.
1. Resolve TTR-LEV and TONE-PT errors, if any.
2. If neither condition exists, retry the command at 1-minute intervals a
maximum of 5 times.
1004
ABORT
The port was in use on a valid call.
1. Determine whether the port is available for testing (status
data-module).
2. When available, retry the command at 1-minute intervals a maximum of
5 times.
1020
ABORT
An existing Error Type 769 on this port prevented the test from running.
1. Follow the procedures for Error Type 769.
2000
ABORT
Response to the test command was not received within the allowable time
period.
period.
2100
ABORT
Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals a maximum of 5 times.
Any
FAIL
The NPE of the tested port was transmitting in error, which can cause noisy
and unreliable connections.
and unreliable connections.
1. Replace the circuit pack.
PASS
The port is correctly using its allocated time slots.
1. Investigate user-reported troubles on this port using other port tests and
examining the ADU, external wiring, and customer equipment.
