Touch Tone Phone: A Comprehensive Guide
Are you considering purchasing a touch tone phone? Do you want to know more about its features, benefits, and how it compares to other types of phones? Look no further! This article will provide you with a detailed and multi-dimensional introduction to the touch tone phone, ensuring you have all the information you need to make an informed decision.
What is a Touch Tone Phone?
A touch tone phone, also known as a multi-frequency (MF) telephone, is a type of telephone that uses dual-tone multi-frequency (DTMF) signaling to transmit touch tones. These phones replaced the older pulse dialing system, which used a series of pulses to represent numbers.
How Does a Touch Tone Phone Work?
When you press a number on a touch tone phone, the phone generates two different tones simultaneously. For example, when you press the number 1, the phone emits a combination of a high tone and a low tone. The combination of these tones is what allows the phone to transmit the number to the destination.
Here’s a table showing the frequency combinations for each number:
| Number | High Tone (Hz) | Low Tone (Hz) |
|---|---|---|
| 1 | 697 | 1209 |
| 2 | 697 | 1336 |
| 3 | 697 | 1477 |
| 4 | 770 | 1209 |
| 5 | 770 | 1336 |
| 6 | 770 | 1477 |
| 7 | 852 | 1209 |
| 8 | 852 | 1336 |
| 9 | 852 | 1477 |
| 0 | 941 | 1336 |
