<=-=*=---------------------------=*=-=> | White Box Plans | | (Uploaded by Agrajag the Prolonged) | <=-=*=---------------------------=*=-=> <=-=*=---------------------------=*=-=> | Overview | <=-=*=---------------------------=*=-=> | | | This article will tell you how | | to change a normal touch tone keypad| | and convert it to a portable unit. | | In addition, we give the touch-tone | | frequencies. | | | <=-=*=---------------------------=*=-=> <=-=*=---------------------------=*=-=> | Instructions | <=-=*=---------------------------=*=-=> | | | First of all, the tones made by | | a touch tone telephone are not | | single tones, they are a combination| | of two tones, making "DTMF" (dual | | tone multi-frequency). The normal | | tone telephone dials 12 different | | signals, but is capable of dialing | | 16 different signals (see bulletin | | on silver boxes). | | | | The power required by a keypad | | is about 25 volts, but they will | | work with as little as 15, thereby | | allowing the use of two 9-volt radio| | batteries. As you may have guessed,| | they are also designed to operate | | with a telephone type speaker (and | | phone line), and not the standard | | 8-ohm speaker which needs to be used| | for adequate volume. To accompolish| | this, we use a matching transformer,| | this is one of those miniqture ones | | available at Radio Shack. Enough of| | the theory, now for the circuit. | | | | You will need: | | | | A touch tone keypad | | | | A miniature 1000 to 8 ohm | | transformer | | (Radio Shqck # 273-1380) | | A standard 8-ohm speaker | | Two 9-volt radio batteries | | Two 9-volt bqttery clips | | A case to put it all in (optional) | | | | A few construction notes, I | | suggest that you solder and tape all| | connections. It is also important | | to read this entire bulletin before | | attempting to construct this. | | | | First, connect the ReD wire of | | the transformer to either terminal | | on the speaker. Now connect the | | WHITE wire from the transformer to | | the other terminal on the speaker. | | Next, connect the RED (positive) | | wire of one battery clip to the | | black wire of the other battery | | clip. Now connect the the remaining| | RED wire on the second battery clip | | to the GREEN wire from the touch | | tone pad. Connect the BLUE wire | | from the touch tone pad to the | | ORANGE-and-BLACK striped wire from | | the touch tone pad. To these two | | wires, now connect tha remaining | | black lead from first battery clip. | | You have now finished the power | | connection t the keypad. Connect | | the BLACK wire from the keypad to | | the BLUE wire on the transformer. | | Next connect the ReD-and-GReeN | | striped wire from the keypad to the | | GReEN wire on the transformer. The | | BLaCK wire on the transformer should| | not be connested to anything, along | | with quite a few wires from the | | keypqd. The connection of the | | keypad is now complete. All you | | have to do is connect two nine volt | | batteries to the battery clips, and | | you'll be ready to go. You may want | | to mount it in a case for easy | | portability. Note that the silver | | box modification CAN be made to this| | unit, allowing complete remote | | phreaking. When none of the buttons| | are pressed, this unit uses NO | | power, thereby eliminating the need | | for a power switch, and extending | | the life of the batteries. | | | | The following are the frequency | | combinations generated by each | | button on the keypad. | | | | KEY FREQ. #1 FREQ. #2 | | --- -------- -------- | | 1 697 1209 | | 2 697 1336 | | 3 697 1477 | | A 697 1633 | | | | 4 770 1209 | | 5 770 1336 | | 6 770 1477 | | B 770 1633 | | | | 7 852 1209 | | 8 852 1336 | | 9 852 1477 | | C 852 1633 | | | | * 941 1209 | | 0 941 1336 | | # 941 1477 | | D 941 1633 | | | | All frequencies are measured in | | Hertz Note that A,B,C and D are not | | normally present (except for silver | | boxes) | | | <=-=*=---------------------------=*=-=>
