Abstract

PURPOSE:To secure optimum communication speed in accordance with a use by judging whether the simultaneous communication of the voice and data or the data communication only is obtained before the communication is started, and executing the data communication in a high speed action mode when the data communication only is obtained. CONSTITUTION:It is judged whether the simultaneous communication of a voice and data or a data communication only is obtained before the communication is started, a control circuit 11 to set the switch of a prescribed mode is respectively provided. In such a constitution, when switches S1-S4 are set to (a), the voice and the data signal of a modulator and demodulator 4 are band- divided, the simultaneous communication of the voice and the data can be executed, and in such a case, the modulator and demodulator 4 are set to a low speed mode. When the data communication only is executed, the switches S1-S4 are set to (b) and the modulator demodulator 4 are set to a high speed mode. Thus, a sound signal is cut, the data communication to use all bands of 0.3kHz-3.4kHz can be executed and high speed data communication can be executed.
