Abstract

PURPOSE:To prevent miscalling, by providing a display device displaying the number inputted to a suitable position of the outside and enabling to confirm if the displayed number after input coincides with the telephone number of opposing party. CONSTITUTION:A timer circuit 5 is immediately reset with a callout pulse of a telephone line 3 inputted from a reset terminal 5a and this pulse is inputted from a delay circuit 6 with a slight delay. The time constant of this circui 5 is longer than the pulse interval at one dial operation and shorter than the operations between one dialing to another dialing. Thus, the output of the circuit 5 is ''0'' when a callout pulse flows and ''1'' at interruption. The number inputted with the dial operation is detected at a counter 7 from a telephone line 3 and after being stored once at a latch circuit 9, it is displayed at 12.
