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 Network Processing Elements (NPEs) reside on each circuit pack
with a TDM Bus interface. (The TN464C UDS1 circuit pack has one
SCOTCH-NPE chip instead of several NPE chips). The NPE controls port
connectivity and gain, and it 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 that it 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 it takes between 20 and 30 seconds to complete.

Result Description/ Recommendation
ABORT System resources required for this test are not available.
1. Retry the command at 1-minute intervals a maximum of 5 times.
1000 ABORT System resources required to run this test are not available. The port may
be in use on a valid call. Use the status access-endpoint <extension>
command to determine when the port is available for testing.
1. Retry the command at 1-minute intervals a maximum of 5 times.
