In the on-hook state, 60V or 48V direct-current voltage exists between telephone lines L1 and L2, after voltage division and bridge rectification are carried out through resistors R3 and R4, the voltage of a port 2 and a port 6 of the 555 timer reaches more than 4V and is in a reset state, and the LED1 and the LED2 cannot emit light.

When the telephone rings, the ring voltage between telephone lines L1 and L2 is coupled via capacitor C2, bridge rectified and sent to port 2 and port 6 of 555 timer, and the voltage is only about 1V. Thus, the 555 timer output is high and only the LED1 is illuminated. At this time, if the speech sound is loud, the LED1 will also flash.

After the conversation is finished, if the handle is not put on-hook, the off-hook state is also equivalent, and the LED2 continues to emit light. Prompting the user that the number of the handle should be placed, otherwise, the incoming call is influenced.
