摘要

In this system, the radio network subscribers have radio transceiver (21 ... 2n) operating in half duplex mode, and the subscribers of the two networks have dialing means to make their calls. An automatic exchange (4) is connected in a telephone line network and to the radio telephone network (31 ... 3q) through a radio connection unit (5) incorporating voice detection means (21, 22), providing for half duplex transmission of calls between the radio network subscribers and between subscribers of the two networks. Selection means (12i, 13i and 14i) sensitive to the dialing means (71 ... 7n, 81 ... 8r) of the two networks are also provided for automatically establishing the telephone calls between all subscribers. Application is found in tactical systems for connecting combat radios.
