NPE Crosstalk Test (#6)

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 usually only part of a port’s long test

sequence and takes approximately 20 to 30 seconds to complete.

1009 PASS Detected tone was not pure dial tone. No action required.

PASS Trunk was seized, and dial tone was detected. User-reported troubles on

this port should be investigated by using other port tests and by examining

trunk or external wiring.

Result Description/ Recommendation

ABORT Could not allocate the necessary system resources to run this test.

1. Retry the command at one-minute intervals a maximum of five times.

2. If the test continues to abort, escalate the problem.

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 trunk group/member number of the port. Use the status

trunk 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. (Refer to the "Status Commands" section in Chapter 10,

"Maintenance Commands and Trouble-Clearing Aids" for a full description

of all possible states.) You must wait until the port is idle before retesting.

1. If the port status is idle, then retry the command at one-minute intervals

a maximum of five times.
