Asynchronous time division communication system

Abstract From the Canadian patent

Asynchronous time division system including at least one node with a switching network (BSN) to which a plurality of user stations (USI/N) are coupled via transmission links and which is adapted to interconnect user stations. At least one (US4) of these user stations is a clock station providing clock information. and upon the establishment of a connection between a Plurality of other user stations (US1/3), with the purpose of exchanging synchronous data, each of these stations establishes a connection with this clock station.
