Figures 1 and 2 are waveform diagrams for explaining one embodiment of the incoming call response circuit of this invention and its operation;
The figure shows the response time in each incoming call ringing state when the incoming call response circuit of this invention is implemented, Fig. 4 is a conventional incoming call circuit diagram, and Fig. 5 shows the off-hook operation at the time of incoming call in Fig. 4. It is a figure which shows the time until a response (loop closure). In the figure, 2 is the first contact, 5 is the incoming call response relay,
11 is a capacitor, and 12 is a second contact.
