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.
1018 ABORT Test has been disabled via administration.
1. Verify that the
Maintenance Tests? field on the Trunk Group
Form is set to n. To enable the test, issue the change trunk-group x
command where "x" equals the number of the trunk group to be tested.
Then change the entry in the
Maintenance Tests? field on the
form to y.
1005 ABORT Trunk has been administered as incoming-only; or DID trunk group type;
dial tone can only be obtained on outgoing trunks. This is a normal
condition.
2000 ABORT Response to the test was not received within the allowable time period.
1. Retry the command at 1-minute intervals a maximum of 5 times.
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.
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.
