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, one-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.

Result
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. Use the display port PCSSpp
command to determine the station extension of the port.
Use the status station 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 this test. You will
have to wait until the port is idle.
2. If the port status is idle, then retry the command at
1-minute intervals a maximum of 5 times.
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 disconnect button on DTDM. Retry the
command after 1 minute.

CAUTION:
This action drops the call in progress.
