Abstract: PURPOSE:To shorten a transmission time by informing the receiving side with one-stage accelerated digital image transmission speed from the analyzed result of a decoding error degree informing signal received by a modulator/demodulator when the decoding error is a specified value or below and providing a control circuit for retraining of a demodulator circuit. CONSTITUTION:When a decoder 3 monitors received image signal data by the data group and recognizes the decoding error due to a noise on a facsimile communications circuit, it outputs said error to a counter 4, which counts decoding errors. After the 1st communications control circuit 5 finishes decoding image signal data of one page, it gives to the modulator circuit 1 instructions for generating and transmitting a communications sequence signal for informing a transmitting side 10' of the degree of the decoding error with the aid of the value outputted by the counter 4. An analysis circuit 6' analyes the informed communications sequence signal data. When the error count value is below the specified one, the 2nd communications control circuit 7' indicates the receiving side 10 the higher image signal transmission speed than the previous time. The modulator circuit 1 at the receiving side 10 is trained at the new image signal transmission speed, which is improved, and the transmission time is shortened.
