System Technician-Demanded Tests: 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 NPE Crosstalk
Test, for example, you may also clear errors generated from other tests in the
testing sequence.
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 about 20 to 30 seconds to complete.

Could not allocate system resources to run this test or an internal system
error (software) occurred.
1. Retry the command at 1-minute intervals a maximum of 5 times.

ABORT
System resources required to run this test are not available. The port may be
in use on a valid call. Use status station or status trunk command to
determine when the port is available for testing.
1. Retry the command at 1-minute intervals a maximum of 5 times.
