Abstract

PURPOSE:To make transmission of information with success of training confirmed without destroying training, by using a high speed MODEM which can have back- ward channel in addition to the message channel. CONSTITUTION:A transmission control section at transmission and reception side is connected to a facsimile line 11, and a control circuit 12R make the speed of a high speed MODEM16R for message channel coincidence with that of a high speed MODEM16S at transmission side. At the reception side, the high speed MODEM16R makes training of the high speed MODEM16S. The control circuit 12R checks the state of reception and discriminates if the training is successful. If the successful, the result of discrimination is informed to the transmission side by using the backward channel different from the message channel. At the transmission side, this is received at a backward channel MODEM17S, the control circuit 12S confirms it to start the transmission of the message with the high speed MODEM16S.
