BERT Testing for CTP Bundles Overview
The CTP series provides Bit Error Rate Tests (BERT) for bundles. Each bundle can have a BERT transmitter and receiver that can transmit and receive a pseudorandom sequence of data using a pattern that you specify. You can set up the BERT to transmit the data sequence toward the serial interface or toward the IP network. User data is replaced with the data sequence in the direction that you select.
You can set up BERTs in the following directions:
Toward the serial interface and the attached customer device.
Toward the IP network and the remote customer device. This configuration is called end-to-end BERT.
BERTs do not run on bundles that use transparent encoding or on fractional T1/E1 bundles.
