ABSTRACT:
A digital switching system (10) in accordance with the invention includes a digital switching matrix (12) having an input bus and output bus; a plurality of information systems (18, 20 and 22) with each information system having an information bus for transmitting and receiving information using a protocol which is different from a protocol used by the information bus of each of the other information systems with the information buses of the information systems being electrically connected to the input and output buses of the matrix to permit information transmitted on any of the information buses to be received by any of the information buses through the input bus, the switching matrix and the output bus; a host processor (34), for controlling the information systems with commands; and a control processor (16), for generating control signals controlling switching of switches of the digital switching matrix.
