- Touch tone fones:
-
- As most of you know a touch tone fone produces a sound
- when a key is pressed. What some people don't know, however,
- is that this tone is actually 2 sounds. This system is
- referred to as DTMF (dual tone multi-frequency). Here is a
- list of both tones' frequencies :
- KEY FREQ. #1 FREQ. #2
- --- -------- --------
- 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
-
- These freq. are measured in Hertz.
-
- Red Boxes:
-
- Here are some money frequencies to use with the red box.
- Although 1 piece of real $ is needs to be sent first the
- red box duplicates the rest. ms=millisecond 1700hz & 2200hz mixed together
-
- nickel-66ms on (1 beep)
- dime-66ms on, 66ms off, 66ms on (2 beeps)
- quarter-33ms on, 33ms off (repeat 5 times)
-
- Silver Boxes:
-
- Sliver boxes change the 3,6,9,# keys on a touch tone
- fone to A,B,C,D As with a regular key these use DTMF.
- KEY FREQ. #1 FREQ. #2
- --- -------- --------
- A 697 1633
- B 770 1633
- C 852 1633
- D 941 1633
-
- These freq. are in Hertz.
-
- Green Boxes:
-
- A disadvantage of these is that they must be used by the called party.
- The freq. here should be used only after a signal is sent to alert
- the MF detectors at the CO. This is done by sending 900 + 1500 Hz or
- a single 2600 Hz (90 ms) tone followed by 60ms of silence and then
- the tone you want for at least 900ms. Here are the freq. in Hertz :
-
- Coin Collect 700 + 1100
- Coin Return 1100 + 1700
- Ringback 700 + 1700
