DTMF (dual tone multi frequency) is the signal to the phone company that you generate when you press an ordinary telephone's touch keys. In the United States and perhaps elsewhere, it's known as Touchtone phone (formerly a registered trademark of AT&T). DTMF has generally replaced loop disconnect (pulse) dialling.
