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.

Result Description/ Recommendation
1000 ABORT System resources required to run this test are not available. The port may
be busy with a valid call.
1. Use the display port UUCSSpp command to determine the station
extension or trunk group/member number of the port. Use the status
bri-port UUCSSpp 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.
2. If the port status is idle, then retry the command at 1-minute intervals a
maximum of 5 times.
1004 ABORT The port has been seized by a user for a valid call. Use the status bri-port
command to determine when the port is available for testing.
1. Retry the command at 1-minute intervals a maximum of 5 times.
2. If the test continues to abort and the port is not in use, escalate the
problem.
1005 ABORT This test is not valid for this type of translation. Ports administered as
“ASAI” or “ADJK” can not run this test, because the B channels associated
with the port are not used by ASAI or Lucent Adjunct Links. This is a normal
condition.
2012 ABORT Internal system error
2100 ABORT Could not allocate the necessary resources to run this test.
1. Retry the command at 1-minute intervals a maximum of 5 times.
