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
2000 ABORT Response to the test was not received within the
allowable time period.
1. Retry the command at one-minute intervals a
maximum of five times.
2. If the test continues to abort, escalate the problem.
FAIL Trunk was seized, but dial tone could not be detected.
1. Check for errors on TONE-BD or TONE-PT. Clear
any errors found and repeat test.
2. If error has still not cleared, refer problem to CO.
2002 FAIL Seizure portion of test failed due to hardware problem.
Fault is usually caused by a disconnected trunk.
1. Check trunk wiring to ensure good connection;
repeat test if wiring correction made.
2. Locate another identical CO trunk and swap its
wiring with one under test. Repeat test on both
trunks and determine if problem follows trunk or
remains at original port. If problem follows trunk,
refer problem to CO. If problem remains at port,
replace circuit pack and repeat test.
3. If replacing circuit pack does not clear failure,
escalate the problem.
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.
