PURPOSE:To obtain an efficient communication without deterioration of the video quality, even if the channel is altered by reading out the characteristic data corresponding to the line from a memory circuit and adjusting a modulation/demodulation device, equalizer and waiting time. CONSTITUTION:The system is provided with a memory circuit 11 which stores the characteristics per line connected to specific correspondence party, such as adjusting value of an equalizer, amplifier gain of modulation and demodulation device, and waiting time of response signal. Further, when a communication control circuit 10 reads out the characteristic data corresponding to the said line from the circuit 11 at the start of correspondence and the modulation and demodulation devices 6 and 8, equalizer 7 and the waiting time are adjusted, allowing to make efficient communication without incurring the deterioration of video quality, even if the facsimile channels are changed. |
