Hybrid Circuit and Conference Circuit Test (#57)
This test checks two different port circuit functions. It performs an analog reflective looparound
measurement on the port’s hybrid circuitry. The Conference Circuit test performs a conference
test on the port’s Network Processing Element (NPE).
For the test results to be valid, a voice terminal must be connected to the port being tested. The
test instructs the on-board microprocessor to put the port in analog reflective looparound mode.
The Tone-Clock circuit pack supplies a 1004-Hz tone to the port’s listen time slot and a GPTD
(General-Purpose Tone Detector) measures the level of the reflected signal appearing on port’s
talk time slot.
The Conference test is performed only if the Hybrid Circuit test passes. The Conference Circuit
test verifies that the NPE can correctly conference several test tones together. The test is
executed in two parts. The first half of the test verifies operation of the NPE’s first three
conference chels, and the second half verifies the NPE’s remaining four conference chels. The
test puts the NPE in looparound mode and instructs it to talk on a specified time slot while
listening to a 1004-Hz tone using the Conference Chels. A GPTD then measures the signal and
noise levels of the conferenced output and reports whether or not these fall within a specified
acceptable range.
This test is run on HYB-LINE (Hybrid Line) and MET-LINE (MET Line).

ABORT Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals up to 5 times.
1000 ABORT System resources required to run this test are not available. The port
may be busy with a valid call.
1. Enter display port location to determine the station
extension of the port.
2. Enter status station to determine the service state of the port.
If the port is in use, wait until the port is idle before retesting.
3. Retry the command at 1-minute intervals up to 5 times.
