NE-95-MK (009A/4) "Multiple Access Radio Telephone System Selectively Operating on Full-Duplex and Half-Duplex Modes" ABSTRACT OF THE DISCLOSURE A multiple access radio telephone system is connected to a telecommunication switching system and serves a group of N remote stations through M two-way radio channels (where M is smaller than N). The remote stations have corresponding subscriber line terminals in the switching system and are accessible to one of the two-way radio channels-selected by a concentrator. For efficient channel utilization, the concentrator establishes a full-duplex mode connection between -one of the corresponding subscriber line terminals of the switching system and the selected two-way radio channel in response to a request for an extragroup call and establishes a half-duplex mode connection between two of the remote stations through the selected two-way radio channel in response to a request for an intragroup call.
