Abstract
PURPOSE:To inhibit the transmission of data to a circuit for a fixed period of time after an off-hook state and to make a switchboard recognize surely the transmission data, by using a prepause timer to an output control circuit which controls the transmission of data in response to the input to set an inhibiting period for transmission of data based on a hook signal. CONSTITUTION:The D type FF circuits 211-21N are added to plural prepause timers 22 of a dial circuit which optimizes the prepause time and period during which the output of data is inhibited to a circuit. Then the voltage produced by a resistance 27 in response to the open/close states of a switch 26 is applied to the reset inputs, the inverse of R, of circuits 211-21N respectively as a hook signal HK. At the same time, the output received from an AND circuit 30 is inputted to the clock inputs of circuits 211-21N. The open/close states of the switch 26 are checked and the timer 22 outputs the logic value H or L in response to the state of the switch 26. Then the prepause PP is delivered in response to the state of the switch 26 for control of an output control circuit 12. Thus the transmission of data is inhibited to the circuit for a fixed time after an off-hook state.
