Claims

[Scope of utility model registration request]

A modulation/demodulation circuit, an interface terminal connected to one input/output terminal of the modulation/demodulation circuit to which an input/output terminal of an information communication control device is connected/disconnected, and an input/output terminal of an acoustic coupler connected to a handset of a telephone set. an acoustic coupler terminal to be connected and disconnected; a telephone line terminal to which a telephone line is connected and disconnected; a telephone terminal to which a telephone input/output terminal is connected and disconnected; a first operating switch for selectively connecting a telephone line terminal and the telephone terminal; a second operating switch for selectively switching between automatic reception and transmission; and a second operating switch connected to the telephone terminal; an automatic reception section that receives a signal from the telephone line terminal when in an automatic reception state and switches and connects the telephone line terminal to the other input/output terminal side of the modulation/demodulation circuit; The signal from the modulation/demodulation circuit can be output to the telephone line terminal by switching the second operating switch to the transmitting side while the telephone line terminal and the telephone terminal are selected. A portable modem for telephone lines.
