A network of telephone subscribers, located remote from the primary telephone system, includes subscriber stations having two frequency-agile, multi-channel duplex transceivers for communicating with a central office having one duplex transceiver for each channel. The central station includes controls for automatically configuring subscriber stations as repeaters to permit calls to and from other subscriber stations to be routed through repeater-configured subscriber stations. Signalling is transmitted out of band so that it can be transmitted via intermediate subscriber stations which may be involved in another call. The most direct available route for each call is continuously updated during the progress of the call to minimize the number of subscriber stations involved in the call. Each subscriber station serves two subscriber loops and permits calls between those loops without transmission via the central station. Likewise, calls between subscriber stations do not pass through the central station. The subscriber stations may be mobile radio-telephone stations.

The method of servicing telephone subscribers, which are not physically connected into a primary telephone system, by means of a network having a central station and plural spaced subscriber stations, the central station serving to provide access to the primary telephone system for the network subscribers, the spaced subscriber stations each serving to provide access to the network for at least one subscriber by transmitting and receiving calls intended for that subscriber, said method being characterized by the steps of: relaying calls to subscriber stations located beyond the transmission range of the central station by means of at least one of several others of said subscriber stations configured as a repeater station, said other subscriber stations being capable of receiving and transmitting calls via more than one frequency which is selected by the central station; and automatically changing, in mid-call if necessary, the subscriber stations used as repeater stations for a call, as call traffic permits, to minimize the number of subscriber stations so used.
