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, 1-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.

Error Test
Code 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
2. If the port status is idle, then retry the command at 1-minute intervals up to
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 up to 5 times.
2. If the test continues to abort and the port is idle, escalate the problem.
1005 ABORT This test is not valid for this type of translation. Ports administered as "ASAI" or
"ADJK" cannot run this test, because the B channels associated with the port
are not used by ASAI or Avaya 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 up to 5 times.
1, 2 FAIL The NPE of the tested port was found to be transmitting in error, causing noisy
and unreliable connections. Error code 1 indicates that the NPE Crosstalk test
failed on Channel B1. Error code 2 indicates that the NPE Crosstalk test failed
on Channel B2.
1. Replace circuit pack.

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.
