ABSTRACT:
A facsimile terminal communicates facsimile data with an opposite facsimile terminal through an ISDN circuit. Even if the communication speed of the facsimile terminal is different from that of the opposite terminal, the facsimile terminal can surely exchange the facsimile data with the opposite terminal. The facsimile terminal includes a transmission and reception unit for transmitting and receiving data to and from the opposite terminal through the ISDN circuit, a receiving condition judging unit for judging or determining whether or not the transmission and reception unit receives data normally. The facsimile terminal also includes a speed switching instruction unit for providing a speed switching instruction when the transmission and reception unit does not normally or successfully receive data. In addition a speed switching control unit is provided for switching the communication speed of the transmission and reception unit from one speed to another according to the speed switching instruction.
