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 
TDM Loopback 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.
