ABSTRACT:
The present invention generally relates to a network and method capable confirming proper communications of high data rate optical signals between communications network devices. In particular, the present invention teaches a method of creating a "Line Trace" byte to be placed in the Line Overhead portion of the Transport Overhead of a SONET STS-1 frame optical data signal. Current Line Overhead does not incorporate any Trace functionality. With the increasing use of optical cross-connect switches within a communications network, it is essential for a network service provider to have the flexibility to move Line Terminating Equipment around via the optical switches. Thus, the present invention offers a straightforward, efficient way to achieve this necessary flexibility.
