Abstract
A method of and system for detecting and reporting faults in an all-optical communications system. The system monitors each of the optical fibers and uses the optical supervisory channel system to detect and report faults. Whenever the system detects a fault in any of optical fibers, the system forms a message identifying the fault and transmits the message in the optical supervisory channel carried by at least one of the optical fibers.
