Abstract
PURPOSE:To realize the rapid transmission of information signals by transmitting information only while the information signal changes, by operating a timer by detecting the change of the information signal. CONSTITUTION:Once contacts of contact signal generator 1 and information change signal generator 6 of subrodinate office 200 all turn from OFF to ON through the change of an information signal, an output after passing through differentiating circuit 7 triggers timer 9 to operate for time T1, and during this, the information signal is inputted to step oscillator 10 to generate a tone signal at frequency (fa) equivalent to the input, so that the signal will be transmitted to master office 100. With contacts turned from ON to OFF, timer 9 is driven through circuit 7 again, and a signal is transmitted at frequency (f0) for time T1. In this way, tone signals are generated and transmitted at the frequency which corresponds to the combination of the operation of contacts of generator 1.
