Can someone give me the frequencies for touch-tone phones? I am working on a little project using my HP 28s. Thanks. Respond here or e-mail me at "tonys@uiuc.edu".

What I mean is, I need the tones corresponding to the numbers, 0-9, and the two special characters, * and #.

Hope this answers your question. 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 *: 941+1209 0: 941+1336 #: 941+1477 Let me know if you have any other questions. -- Bruce

I'm not sure on the # and * keys but here are the numbers (2 frequencies for each number)... Freq ---- 697 1 2 3 770 4 5 6 852 7 8 9 941 0 1209 1336 1477 <- 2nd Freq. Hope this helps some! Dave Downin

Anyone have an idea or care to guess what they do? Fo = 697Hz & 1633Hz F = 770Hz & 1633Hz I = 852Hz & 1633Hz P = 941Hz & 1633Hz watmath!focsys!brad

The addition of these four tone pairs creates a 4x4 matrix. These additional tones are used for specialized control purposes, but not, in general, to access any function or servce provided by a telephone company; 4x4 DTMF keypads are readily available for telephone and two-way radio use, but are no where near as common as the conventional 3x4 DTMF keypad. These keys are more commonly labeled "A", "B", "C", and "D", with "A" on the top row and "D" on the bottom row. The 4x4 DTMF matrix was first used with the military AUTOVON switched voice network starting around 1963, and did not see other use for several years. The key designations indicated above are the AUTOVON designations, and refer call precedence control as follows: FO = Flash Override highest call precedence; nudet on the horizon :-) F = Flash traffic I = Immediate traffic P = Priority traffic Larry Lippman @ Recognition Research Corp.

Don't have the tones handy but can find them if anyone is interested. It could be that the four tones listed above correspond to A,B,C, and D. --- Jeff +-----------------------+-----------------------------------------------------+ | Jeff DePolo N3HBZ | Internet: depolo@eniac.seas.upenn.edu | | Univ. of Pennsylvania | RF: 146.685- 224.40- 442.70+ 144.455s (Philadelpia) | | Computer Science Eng. | Twisted pair: (215) 386-7199 home | | Class of 1991 | Carrier pigeon: 420 South 42nd St. Philly, PA 19104 | +-----------------------+-----------------------------------------------------+
