Dual Tone Multiple Frequency. Pressing a button on the keypad of a touch-tone phone generates a pair of tones of specified frequency and duration. The network or the equipment at the other end of the connection (such as a remote control for a phone answering machine) detects and interprets these tones. In analog networks, audible tones generated by the network provide the call progress indications to the user. Different tones allow the human ear to interpret the progress of the call. On digital networks (such as PBX or ISDN), the network may send indication messages to the phone to indicate the status of the call, and the phone may generate most tones locally, driven by those messages.

Pushing a button on a telephone keypad generates a sound that is a combination of two tones, one high frequency and the other low frequency. echo canceling A method of controlling echoing on communication lines, in which the sender checks the inbound channel for a slightly delayed duplicate of its own transmission. In echo canceling, the sender adds an appropriately modified, reversed version of its transmission to the path on which it receives information. The result is to erase the echo electronically but leave incoming data intact.
