b. This error type indicates that the circuit pack been removed or has been
insane for more than 11 minutes. To clear the error, reinsert or replace the
circuit pack.
c. A transient error that does not cause an alarm can occasionally occur
during a SPE, TDM BUS, or Tone Clock interchange. Test the port and
follow the instructions for conference Test (#7).
d. This error is not service-affecting and no action is required.
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.
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 occur. This test is usually only part of a port’s Long Test Sequence and takes
about 20 to 30 seconds to complete.
