ABSTRACT:
An overhead processor processes overhead bytes in a stream of Synchronous Optical Network (SONET) frames in multiple levels. In one embodiment, the overhead processor includes three stages. A first stage provides access for external processing of a first set of overhead bytes in the stream of SONET frames. A second stage is programmable to process a second set of overhead bytes in the stream of SONET frames. A third stage processes a third set of overhead bytes in each frame in the stream of SONET frames.
