What is the DTMF generator?

The

DTMF generator refers to any electronic device capable of generating dual tone signals (DTMF) used for dialing phones with touch tone. The DTMF dialing system works through the keyboard configuration in three columns along four grid rows, representing 0 to 9 and other special characters such as # and * keys. The touch pad grid is arranged by assigning a specific high frequency for each column and a specified low frequency for each row. For example, when the number of "2" is pressed on the keyboard, a unique sound sinus tone is emitted by mixing a pure high frequency of 1,336 Hz with a clean low frequency of 697 Hz. The DTMF signal tone generated by the keyboard is then transmitted to the local office of the telephone company where it is translated or decoded into the possession of the corresponding digits that allow you to dial the specified telephone number. After introduction, the touch tone became a standard dialing system for phones in the United States and was eventually adopted throughout the SVětě.

DOTUM-TTE DIVING allows you to activate and communicate with DTMF compatible equipment. This type of dialing allows users to remotely control and activate and connect with many call routing, voice mail systems, or other auxiliary telephone devices that can decode the signals created by the DTMF generator. The DTMFouch-Tion Dialing T-based T phones allow consumers to access their account balances in banks, as well as to obtain additional information from organizations that provide DTMF-based telephone interfaces.

The

computer equipped with an audio card and digital sound software is able to act as a DTMF generator by creating multiple frequencies of double tone used on phone keyboards of touch tones. The software program interprets the phone digits and then generates the appropriate audio files that match the standardIzed frequency tones of paired DTMF. The dialing process can be activated either by mice by clicking or using the keyboard commands. This allows fast automated computer dialing of outgoing phone numbers and uses them many businesses.
