Communication switching module for the transmission and control of audio, video, and computer data over a single network fabric

摘要

A communications switching module (CSM) serving as common switching equipment for work stations in a star-topology Ethernet local area network. Both voice and data are incorporated in master Ethernet packets which are transmitted at a constant rate. The CSM switches the voice signals synchronously over a time domain multiplexed highway and separately switches the data signals asynchronously over a high speed packet bus.
