Dual Tone Multiple Frequency Also known as Touch Tone, a Bell System trademark DTMF tones are used in two major ways on the scanner bands One is for dialing up hospitals on the HEAR frequencies or for dialing up regular telephone numbers and control codes on ham and business repeater systems The other is sending mobile unit identification automatically when the microphone is keyed (see ANI)
Dual tone multi- frequency: commonly known as touch-tone or push-button dialing, as opposed to older-style pulse or rotary dialing The tone frequencies defined under DTMF are globally standardized, making it possible to use push-button inputs for a wide variety of applications such as interactive voice response Brooktrout Technology

Dual Tone Multi Frequency Commonly known as 'touch-tones', this in-band signaling is made up of two tones (out of a group of 8) and is used to translate dialed digits
Dual Tone Multi-Frequency Describes tones generated from pressing buttons on a touch tone phone These tones are composed of two separate sine waves
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
Facility for sending multi-frequency tones across the network from a phone Each number, when pressed, transmits its own individual sound Necessary for accessing some network features (such as voicemail) or for some information services
Dial Tone Multifrequency The tones generated by punching in numbers on a telephone key-pad
