E-DIG-STA (Emulated Digital Line)
Digital Line NPE Crosstalk Test (#9)
One or more Network Processing Elements (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 about 20 to 30 seconds to complete.
Crosstalk testing occurs on both the primary information channel (voice) and the
secondary information channel (data) associated with each digital station port. If
this test fails on either channel, the station and the DTDM are taken out of service.

Error Test
Code Result Description / Recommendation
1 ABORT During testing of the primary information channel, system resources may not
have been available or the port was busy during the test.
1. Check the port status.
2. Use the display port UUCSSpp command to determine the station
3. If the port status is idle, then retry the command at 1-minute intervals up to 5
2 ABORT During testing of DTDM, system resources may not have been available or he
port was busy during the test.
1. Check if port is being used. If possible, disconnect by toggling the

1000 ABORT System resources required to run this test are not available. The port may be
busy with a valid call.
1. Use display port UUCSSpp to determine the station extension or attendant
2. If the port status is idle, then retry the command at 1-minute intervals up to 5
1001 ABORT System resources required to run this test are not available.
