PURPOSE: An apparatus for automatically controlling a cable equalizer characteristic inside of a modem of a facsimile is provided to reduce an error in a communication by automatically controlling a cable equalizer characteristic inside a modem suitable to a line condition. CONSTITUTION: A central processor checks whether a line is formed(101). The central processor detects a line electric current value supplied to a facsimile and checks whether data are approved(102). In case a detected current value is 15-25mA(103), the central processor sets a cable equalizer characteristic as an appointed value(107). In case a detected current value is 26-35mA(104), the central processor sets a cable equalizer characteristic as an appointed value(108). In case a detected current value is 36-55mA(105), the central processor sets a cable equalizer characteristic as an appointed value(109). In case a detected current value is more than 56mA(106), the central processor sets a cable equalizer characteristic as an appoint value(110). The central processor performs transmitting or receiving a fax(111).
