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.

Result Description/Recommendation
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.
1000 ABORT System resources required to run this test are not available.
The port may be in use on a valid call. Use status
data-module to determine when the port is available for
testing.
1004 ABORT The port has been seized by a user for a valid call. Use status
data-module to determine when the port is available for
testing.
1. Retry the command at 1-minute intervals a maximum of 5
times.
1020 ABORT The test did not run due to an already existing error on this
port (Error Type 769).
1. Refer to the procedure for Error Type 769. If Error Type
769 still occurs on this port, replace the circuit pack.
2000 ABORT Response to the test request was not received within the
allowable time 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 conference circuit test failed (possible off-board problem).
1. Busyout and release the port (data line), and then retest.
2. Replace the circuit pack if the test continues to fail.
PASS The port can correctly conference multiple connections.
User-reported troubles on this port should be investigated
using other port tests, examining the ADU, external wiring,
and customer equipment.
