Abstract

PURPOSE:To ensur an easy operation of the telephone at any seat in a car, by providing the dial signal compounding circuit plus the talking reception amplifying circuit corresponding to the car telephone to the branch connecting device. CONSTITUTION:The dial signals are compounded by the dial signal compounding circuit 24, and at the same time the talking transmission aural signals are compounded by the talking transmission amplifying circuit 28 consisting of the adder amplifying circuit to be delivered to the mobile telephone. Under such conditions, the talking reception amplifying circuits 25 and 26 are provided in the number corresponding to the number of the car telephones. Thus the two car telephones can be connected to another mobile telephone in order to secure both the originating and incoming calls through either one of the two car telephones. At the same time, the talking transmission amplifying circuit 28 is constituted so that the talking transmission aural signals sent from the two car telephones can be compounded with no interference to each other. As a result, a simultaneous talking becomes possible among the two car telephones and the remote subscriber each.
