Abstract

PURPOSE:To perform the transmission and reception of information in good condition through a simple constitution and without shifting down the speed of transmission in the case of an international circuit, by discriminating the characteristics of a transmission circuit to a distance and selecting an equalizer in response to the distance to put the equalizer into the circuit. CONSTITUTION:The facsimile information is transmitted or received by a network controller NCU or a modulator/demodulator MODEM which is connected to a telephone circuit. A switch 4 is connected between the controller NCU and the MODEM. The switch 4 is switched by a system controller SCU that measures the time T1 and T2 during which an answer signal PCS which selected the receiving function is received after controlling the overall working of a system and transmitting an instruction signal DIS including the receiving function. Then the characteristics of the circuit is discriminated by the controller NCU in response to the distance, and an equalizer 3 connected between the NCU and the switch 4 is selected. Then an equalizer 3 suited to a transmission circuit is inserted to transmit and receive the information in good condition without shifting down the speed of transmission.
