Abstract
A facsimile device includes a device capable of transferring and receiving a message in a user-to-user signaling manner and an S-type interface card which is connected to an integrated service digital network (ISDN). According to the present invention, the facsimile device transfers and receives messages through a D channel to be used for transferring signals in the user-to-user signaling manner even though the facsimile device communicates with another facsimile device through B channels of the ISDN to transfer and receive data. Accordingly, channels provided to the facsimile device can be efficiently used.
