How To Build a Silver Box ------------------------- tools and materials : soldering iron, solder, some 22 ga. wire, a spdt switch, and a screwdriver. (1) unscrew your phone (must be a touch tone, desk type) (2) remove the mounted pad and take the clear plastic cover from the bottom. (3) hold the pad with the numbers 0, *, # facing you, and turn it upside down, so you can see the yellow pc board. (4) you should see 2 black round doughnuts. (5) position the board so the solder points for the left doughnut face you. (6) count over four points from the left, and attach a (green) wire to that point. (7) between you and the doughnuts, there should be 2 long yellow capacitors. to the right of these, and on the edge of the board there should be 3 gold contacts. we will use the one on the left. (8) the contact originally is spot welded, so snip it open. (9) to the one nearest you, attach a wires out of the phone, and solder the switch. (11) the orientation should be (red) to center. the switch will now alternate between normal and 1633hz fourth column tones. --------------------------------------- Silver Box Documentation (contributed by lex luthor) the silver box transforms keys 3,6,9,# to a,b,c,d. those tones stand for: "a"-flash "b"-flash override (priority) "c"-priority communication "d"-priority overide (top military) those keys only work on certain networks. Now what do you do with those extra tones??? call any long distance directory by dialing (area code) 555-1212 and while it rings press the # key then as the operator answers you will disconnect them instantly and hear a pulsing tone, press 6(normal tone) and it will stop.then if another person does the same thing on another line and then presses 7 you should have a voice link, area code 414 is good for one that you can screw around with the tones and see what you get.
