Modem Pool Conference Test (#97)
This test is destructive.
This test checks most of the switching and gain control functions provided by the
NPE circuit in the analog section of the conversion resource. This test
conferences a 1004-Hz tone through the NPE, looping it back so that it can be
verified with a Tone Detector circuit.
ANY FAIL The NPE of the tested port was found to be transmitting in
error. This condition causes noisy and unreliable
connections.
1. If the remaining ports are currently not in use (that is,
yellow LED is off), attempt to reset the circuit pack.
Then repeat the test.
2. If the test fails again, replace the circuit pack.
PASS The port is correctly using its allocated time slots.
User-reported troubles on this port should be investigated
using other port tests and by examining station, trunk, or
external wiring.

Result Description/Recommendation
ABORT System resources required for this test are not available.
1000 ABORT System resources required to run this test are not available.
The port may be in use on a valid call. Determine whether
the port is available for testing.
1002 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.
Refer to TDM-BUS (TDM Bus) Maintenance documentation
to diagnose any active TDM Bus errors.
1. If the system has no TDM-BUS errors and is not
handling heavy traffic, repeat the test at one-minute
intervals a maximum of 5 times.
