where & How DTMF details in my contact details used?
Q. Hi, In my N73, i see that I can add "DTMF" details to each contact. I would like to know where and how this DTMF info is used? I understand DTMF is used for identifing which key was pressed, please tell me some use cases. Thanks, San

A. You are right, DTMF (Dual-tone multi-frequency ) is used on touch tome phones to identify the key pressed, one tone for "vertical" column, another tone for "horizontal" row. Your (Nokia) N73 has a feature which allows you to store a series of such tones, representing key strokes. Now why would you need that...? I give you a few examples: a) You always (say) call different numbers in ShenZhen China, and you are "too lazy" to always dial 011 86 755 before the actual number. You can store that sequence. b) You control your home security system over the phone from anywhere. After you call the dial-in number, you need to enter a password, and then you enter another sequence which turns on your driveway lights. You can store those key… [cont.]

What does DTMF stand for on my phone set up?
Q. Does anybody know what DTMF stands for on my initial phone set up option?it gives me these choices-short,long or off.
Asked by Andrea C - Mon Mar 10 12:32:20 2008 - - 3 Answers - 0 Comments
A. 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, or a telephone interconnect system) 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.

A. DTMF are the tones you get when you press a digit key. Used for example to select options on an automated banking system. Press 1 for balance etc. The duration of the tone is the option given. Probably doesn't matter which you choose. I guess it must be a CDMA phone. In GSM, the tone generation is done by the exchange and not the phone.

A. This is somewhat like old school hacking. People would use a "Bluebox" to hack phone companies and stuff with dial tones. Anyways, there is a huge problem with this. Allot of dial tones aren't the same. Like some phones may have slightly different tones for their numbers. Like a previous post said, try calling a bank or you could even try calling your phone company to ask.

A. What exactly are you trying to do? How would you convert DTMF to FSK? FSK in Baudot code or what? I've never heard of anyone converting touchtone signaling to frequency shift keying. Not knowing what the application is, I think you could make something work with a sound card interface. Others have had no problems writing modules which encode and decode DTMF signaling, and the same goes for FSK and I've seen speeds up to 9k6 using a sound card interface although I can't imagine any touchtone signalling requiring that high of a bit rate.
