Abstract

PURPOSE:To increase the transmission efficiency by detecting the aural signals and the like then securing an automatic variation of the transmission velocity for the data communication in case the digital aural signals and the like are piled onto the data communication circuit. CONSTITUTION:The data signal sent from computer 9 is transmitted to communication circuit 1 via circuit control computer 7, modulation/demodulation circuit 3 and mixing network 2 each. When telephone 6 is ready for use, automatic transmission velocity control unit 8 switches the timing pulse of circuit 3 via detection signal (b) sent from digital converter 4 and informs this to the reception side via mixing control circuit 2. At the same time, the switching of the data transmission velocity is informed also to computer 9. Nearly the same operation is given in case telephone 6 receives the incoming.
