替えることを特徴とする通話機能付変復調装置。 A network control device that controls connecting and opening a telephone line; a hybrid circuit connected to the telephone line when the telephone line is connected; and a first analog switch to switch and connect one of the two to the input terminal of the hybrid circuit. It consists of a modulation circuit, a transmitting section, a demodulating circuit, one of which is connected to the output terminal of the hybrid circuit by a second analog switch, and a receiving section. A modulation/demodulation device with a telephone call function is characterized in that it switches between data communication and telephone calls.
