Abstract

PURPOSE: To use data transmission equipment both for a wire communication and for a radio communication by switching the line of the transmitting signal and the line of the receiving signal of the data transmission equipment at the time of the wire communication with a telephone line and at the time of the radio communication with radio equipment by means of a switching circuit.
CONSTITUTION: At the time of the wire communication and at the time of the radio communication, the line of a transmitting signal TD and the line of a receiving signal RD of facsimile equipment 1 are switched by a switching circuit 205. At the time of the wire communication, the line of the transmitting signal TD and the line of the receiving signal RD are connected through a transformer 204 to the telephone line. On the other hand, at the time of the radio communication, the transmitting signal TD of the facsimile equipment 1 is outputted to radio equipment 3, simultaneously, a signal received by the radio equipment 3 is outputted to the facsimile equipment 1, and a sound signal from a microphone 5 is outputted through the transformer 204 to the radio equipment 3 at the time of transmitting. Thus, only by the switching operation of the switching circuit 205, the facsimile equipment 1 can be easily used both for the wire communication and for the radio communication.
