This test clears the various error counters associated with each TBRI-PT. This
test passes if maintenance software is able to sucessfully send the downlink
messages; the test aborts otherwise.
NPE Crosstalk Test (#617)
This test is conditionally destructive.
One or more NPEs reside on each circuit pack with a TDM Bus interface. The
NPE controls port connectivity and gain and provides conferencing functions on
a per-port basis. The NPE Crosstalk Test verifies that this port’s NPE channel
talks on the selected time slot and never crosses over to time slots reserved for
other connections. If the NPE is not working correctly, one-way and noisy
connections may be observed. This test is part of a port’s Long Test Sequence
and takes approximately 20 to 30 seconds to complete. Crosstalk testing is
performed on both B-channels (B1 and B2) associated with a BRI port. If this test
fails on either channel, any channel connected to the port is taken out-of-service.
This test aborts if the port and its associated channels are not in the idle state.

Test
Result Description/ Recommendation
1000 ABORT System resources required to run this test are not available. The port may
be busy with a valid call. Use the display port PCSSpp command to
determine the station extension or trunk group/member number of the port.
Use the status bri-port PCSSpp command to determine the service state
of the port. If the service state indicates that the port is in use, then the port
is unavailable for certain tests. Wait until the port is idle before retesting.
1. If the port status is idle, then retry the command at 1-minute intervals a
maximum of 5 times.
