ABSTRACT:
A personal communications system enables the operator to simultaneously transmit voice and data communication to a remote site. The personal communications system is equipped with two telephone line interfaces to allow connection between two remote sites. The connection between the first remote site and the second remote site may operate in an analog voice mode, a digital data communications mode, and a voice over data communications mode. A switch between analog voice mode and digital data communications mode and analog voice mode and voice over data communications mode is performed using switching tones, including calling tones, answer tones, and DTMF tones. Hardware and software switches are also used to program the modems in the personal communication systems for originating and answering modes.
