Abstract
A system for use on communications channels such as telephone lines, makes use of a Token Throwing Multiplexer (TTM) whereby a plurality of multipoint networks each having a master or local station and one or more remote stations and each having a station located at a common site can function as substantially independent networks while using common modems and telephone lines. The TTM uses conventional time division multiplexing (TDM) techniques in the outbound direction. Contention for the inbound line is resolved by a token throwing technique, the current inbound user being the location and channel in possession of the outstanding token.
