Abstract

PURPOSE: To simplify and miniaturize a transmitter and receiver by eliminating the need for a high-speed modem by leading a high-speed digital circuit into a private branch and by connecting a high-speed facsimile equipment, equivalent to the circuit, to several circuits.
CONSTITUTION: Private branch switchboard 3 is connected to terminating equipment 6 of a high-speed circuit through storage controller 7 equipped with large- scale disc memory 75 stored with picture information on a unit of one paragraph, buffer memories 771 and 772 reading and writing information from and a memory 75, and microcomputers 721 and 723 with microprocessors. To this controller 7, simplified facsimile equipment 8 and 9 are connected which consists of a picture read part or a picture print part and simple part such as an operation part, and fixed information compression or information expansion is made, utilizing microcomputers 721 to 723 and buffer memories 771 and 772 provided to controller, at the time of transmission and reception of picture information before the information stored in memory 75, so that units 8 and 9 will transmit and recieve picture information to and from the high-speed circuit.
