Abstract:
1. A method for handling of overhead (OH) bytes of an incoming high order data stream to form a corresponding outgoing data stream, the method comprising a) presenting the incoming data stream as a plurality of N lower order component data streams transmitted in parallel, b) providing a common overhead processing unit (COHPU) capable of handling overhead bytes of a single one of said component data streams, c) forwarding overhead bytes of said component data streams to said COHPU in a circular order, while keeping docketing (ID) information for each particular overhead byte d) processing each of the overhead bytes in the COHPU, at a bit rate of said component data stream, and e) modifying the N component data streams to obtain the corresponding outgoing data stream based on results of the processing and the ID information with respect to each of the processed overhead bytes; wherein the processing step (d) comprises:
