Digital Line NPE Crosstalk Test (#9)

The NPE Crosstalk Test verifies that this port’s NPE channel talks on the se lected

time slot and never crosses over to time slots rese rved for other connections. If

the NPE is not working correctly, one-way and noisy connec tions may be

observed. This test is part of a p ort’s Long Test Sequence and takes about 20 to

30 seconds to comp lete.

16 FAIL The secondary channel is not operating properly. User impac t may range from
noticing nothing to not being able to use this terminal. Check the results of
Voice and Control Channel Local Loop Test (#13). If that test fails, suspect the
Digital Line circuit pack. If that test passes then replace the terminal. If both
test fail, and component replacement does not change the results, then:
1. Run circuit pack tests to check the tone generator circuit p ack and the
Tone Detector circuit pac k using test board UUCSS .
2. Resolve any problems that are detected on the Tone Generator circuit
pack or Tone Detector circuit pack.
PASS Voice and Control Channel Local Loop test passed. All channels are
transmitting properly.
1. To be sure that this is not an intermittent problem, repeat this test up to a
maximum of ten times to make sure it continues to pass.
2. If complaints persist (noisy connections for voice. c orrupted data transfer
for data), examine the station, connections, and wiring.

Result Description/ Recommendation
1 ABORT During testing of the primary information channel, system resources were not
available. Also, the port may have been busy during the test.
1. Enter display port UUCSSpp to determine the station extension of the
port. Use status station to determine the service state of the port. If the
port is in use, wait until the port is idle before testing.
2. If the port status is idle, retry the command at 1-minute intervals a
maximum of 5 times.
