  • Packet-switched data communications system
    Patent number: 4058672
    Abstract: A packet-switched digital data communication system operable in a store-and-forward mode is provided for enabling substantially simultaneous full-duplex communication between a plurality of telecommunications terminals, facsimile transceivers or other data input sources over a communications network with a plurality of other terminals, facsimile transceivers or other data sources having access to the communications network and with which such communication is desired. The disclosed packetizing of data and transmission thereof in a store-and-forward mode with dynamic routing provides a highly efficient utilization of the transmission facilities, substantially error-free data transmission and a handshake capability between a wide variety of dissimilar and otherwise incompatible terminal devices such as facsimile transceivers having differing protocols, modulation techniques and other speed and code characteristics.
    Type: Grant
    Filed: November 10, 1976
    Date of Patent: November 15, 1977
    Assignee: International Telephone and Telegraph Corporation
    Inventors: William C. Crager, Sudhindra R. Umarji, Robert H. Griffin, Gerard J. Louit
  • Packet-switched facsimile communications system
    Patent number: 4058838
