System Technician-Demanded Tests: Descriptions
and Error Codes
Always investigate tests in the order presented in the table below. By clearing
error codes associated with the Voice and Control Channel Local Loop Around
Test, for example, you may also clear errors generated from other tests in the
testing sequence.
NPE Crosstalk Test (#6)
This test is destructive.
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 the port’s long test sequence and takes
approximately 20 to 30 seconds to complete.
