Running a C7BERT
Application
Use this procedure to do the following:
•
local or remote loopback on an NT9X77AA, NT9X78BA, NT9X78CA,
NT9X78DA or NT9X78DB card for LIUBASIC
•
local or remote loopback on an NTEX26AA channelized access link
•
link fault sectionalization
•
CCS7 bit error rate test (C7BERT)
•
inject bit errors during C7BERT
Definition
Tests of bit error rate measure the quality of a CCS7 digital transmission path.
Run a C7BERT in the following conditions:
•
before a CCS7 signaling link goes into service
•
when isolating faults
Common procedures
