1. A multifunctional apparatus for transferring and receiving facsimile data and communication data by using an integrated service digital network (ISDN), comprising:

  • a computer interfacing section for receiving dialing information from a computer, and for transferring the facsimile data and the communication data to, and receiving the facsimile data and the communication data from, the computer;

    a line interfacing section for transferring data to the integrated service digital network, and for receiving the facsimile data and the communication data from the integrated service digital network;

    an ISDN subscriber access controller (ISAC) connected to said line interfacing section for performing layer 1, layer 2 and layer 3 protocols to control a connection with the integrated service digital network by using the dialing information, and for transferring the facsimile data and the communication data to, and receiving the facsimile data and the communication data from, the integrated service digital network at a first data transfer rate; and

    a serial input and output section connected between said computer interfacing section and is said ISAC for converting the communication data transmitted by the computer through the computer interfacing section, and facsimile data scanned in a scanning section, into serial data, and for transferring the serial data to the ISAC at a second data transfer rate, and for receiving and converting the communication data and facsimile data transmitted from the integrated service digital network through the ISAC into the serial data at the second data transfer rate.
