Abstract
A digital multiplexing and demultiplexing system for time division multiplexing a number of incoming plesiosynchronous low rate component signals and a number of incoming plesiosynchronous intermediate rate component signals into an outgoing single high rate signal. A first multiplexing stage time stores and stuffs the low rate component signals and multiplexes them into synchronous intermediate rate signals. A second multiplexing stage stores and stuffs the plesiosynchronous and synchronous intermediate rate signals and multiplexes them into the outgoing high rate signal.
