  • Patent number: 5136634
    Abstract: A method and apparatus for transmitting specifically requested graphic and/or textual data from an unattended database storage location to a requestor's facsimile machine over a telephone line includes a host computer such as a PC modified with a facsimile transmission board and a voice generation board. The host computer receives incoming phone calls and prompts the caller using the voice board to select data files by using the DTMF keys of a standard telephone handset. The PC can be left unattended and can run automatically in the facsimile transmission mode. Callers can immediately access needed textual and image data with the use of just a standard telephone and facsimile machine. Multiple workstation nodes can be configured in a network setup to handle a high volume of calls in real time and to allow multiple data services to operate simultaneously.
