Abstract
Techniques for processing overhead bytes in SONET or SDH frames are provided. Memory stores overhead bytes from the SONET (or SDH) frames. One or more processors load the overhead bytes from the memory. The one or more processors can process the overhead bytes away from the data path at a slower data rate than the data rate of data on the data path. By processing the overhead bytes at a slower data rate, less circuitry is needed to process the overhead bytes. Bytes on the data path are stored in a first-in-first-out delay buffer, while the overhead bytes are processed away from the data path, to maintain alignment between output signals of the processors and bytes on the data path.
