Abstract

A system that allows multiple bundles of plesiochronous digital hierarchy (PDH) payload data streams to be synchronously trasmitted from one point to another is described. The system multiplexes multiple stages of the PDH using a single clock signal. This removes the need to perform stuffing and de-stuffing of the data streams at the various stages of the multiplexing.
