Path protection

Overview

...................................................................................................................................................................................................................................
Purpose
The principle of a path protection is based on the duplication of the signals to be
transmitted and the selection of the best signal available at the path connection
termination. The two (identical) signals are routed over two different path segments,
one of which is defined as the main path and the other as standby path. The same
applies to the opposite direction. The system only switches to the standby path if the
main path is faulty.
