Abstract
In a ringing-tone control device for a telephone set, an audio signal which is sent from a communication opposite party is converted into a corresponding bi-level signal. The bi-level signal is stored into the memory. The bi-level signal is read out from the memory. A ringing tone is generated in response to the bi-level signal read out from the memory.
