Abstract
A dual set of busses is used to provide close coupling between the data and voice services of the CS300 communication system. One of these busses is a time division multiplex bus arranged for communication between port access circuits, and the other bus is a packet-switched data processing bus used for interfacing both with the system peripherals and with the port access circuits. The port access circuits, as well as the faster peripheral circuits, can be connected to either or both busses thereby allowing for the efficient easy interchange of information.
