In a preferred embodiment, at the transmission location, the telecommunications device receives a message at a communications port from a personal data assistant device by an infrared link. Thereafter, the message is coupled to a modem circuit for modulation over the telephone line. The E-mail is routed to a reception location according to a phone number and, upon arrival at the reception location, is routed to or answered by another telecommunications device by means of an identifier emplaced in the caller identification packet. Acknowledgment indicators are also provided to display a status of the message. In another preferred embodiment, the message is input directly into the telecommunications device by means of a graffiti screen integrated therein. The telecommunications device may be integrated into or isolated from an existing telephone. In another embodiment, the telecommunications device may be a bi-directional pager.Field of SearchTELEPHONE LINE OR SYSTEM COMBINED WITH DIVERSE ELECTRICAL SYSTEM OR SIGNALLING (E.G., COMPOSITE)Having transmission of a digital message signal over a telephone line Terminal interface circuitry Digital To plural lines or networks Transmission scheme (e.g., compression/decompression, transmission rate) Having switching station Having format conversion Having station display Having tone code recognition for generating alphanumeric characters Having pressure or position sensitive surface (e.g., touch-screen, light pen) Having conferencing At pay station Having user information display (e.g., telephone number, name, address, etc.) Having electronic mail Having remote database (e.g., videotex system) By voice frequency signal (e.g., tone code) Alphanumeric Having acoustic link COMPOSITE SUBSTATION OR TERMINAL (E.G., HAVING CALCULATOR, RADIO) Interface attached device (e.g., interface with modem, facsimile, computer, etc.) | |
