(assuming the associated circuit pack is plugged in and that the data
module is connected to the associated port), or when a data module is
first connected to an administered port. No system technician action is
necessary.
j. This warning off-board alarm occurs only for G3iV1.1-286 or G3iV2-386.
The alarm occurs when it appears to the system that a DCP endpoint has
been disconnected.
k. A DCP endpoint may have been disconnected.
l. This endpoint is part of processor link. Link initialization has failed (or
demand test for #183 for PI links has failed) and is indicating the
associated PDM as the cause. Check the PDM, the wiring to the PDM and
the link to the far end (i.e. AUDIX DCS, etc.) to resolve the problem.

Descriptions and Error Codes
Always investigate tests in the order presented in the table below when
inspecting errors in the system. By clearing error codes associated with the
Data
Module Internal Loop Around Test,
for example, you may also clear errors
generated from other tests in the testing sequence.
For example, you may also clear errors generated from other tests in the testing
sequence.
NPE Crosstalk Test (#9)
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. If a secondary data module is assigned, it is
