ABSTRACT:
A multiaccess communications system for a communications network in which a plurality of nodes are connected to a head end by a common transmission path to perform wideband transmission of packets between the nodes, particularly a multiaccess communications system such as a carrier sensing multiaccess (CSMA) system or a collision sensing CSMA (CSMA/CD) system. A single transmission cable or a pair of transmission cables are efficiently shared by various channels. Each of the nodes is provided with a transceiver in association with the cable or the cables. All the channels are effectively utilized by means of a relatively simple system construction.
