ABSTRACT:
A communication system for stationary and mobile subscribers includes a number of subscriber stations interconnected in a ring circuit and adapted for two-way communication with other subscriber stations, via a ring circuit. A transceiver station is also connected into the ring circuit and is adapted for two-way communication with the ring, and for two-way wireless communication with mobile subscriber stations, and serves to interconnect the mobile stations for two-way communication with the stations connected with the ring. Each of the subscriber stations of the ring circuit are connected by conventional means with a telephone switching network, and a call directed to such a station is selectively switched to the ring for communication with a mobile station having the same address or identification as the called station. The ring comprises a transmission line in which plural channels are transmitted by time division multiplex, with each station having access to every channel, and adapted to transmit and receive one information block per multiplex frame. The information block contains an address or identification of the called station so that information can be extracted from the multiplex transmission only by the station set having a corresponding address. The ring transmission line may be formed as a light wave guide, and is adapted for use with small, as well as for large systems.
