An SLO Presentation: Box Tones For The Beginner By Damian Here is a compilation of most of the various box tones. Note that all of the frequencies are mesures in hertz. Ok, let's start with the legal... TOUCH TONE FONE DTMF's other file, Bell Abbreviations. One more thing you need to know is that in most tones used by Bell are not one frequency, but the mixture of two. Therefore, you need to produce two different tones at one time. When there are two tones involved, the two frequencies are listed on the same line with a + between them. Note that these frequencies are exact, and should be reproduced exactly. KEY: TONE 1: 699.1 + 1215.9 2: 699.1 + 1331.7 3: 699.1 + 1471.9 4: 766.2 + 1215.9 5: 766.2 + 1331.7 6: 766.2 + 1471.9 7: 847.4 + 1215.9 8: 847.4 + 1331.7 9: 847.4 + 1471.9 *: 948.0 + 1215.9 0: 948.0 + 1331.7 #: 948.0 + 1471.9 SILVER BOX MF's Now we move on to the almost illegal. The Silver Box tones aren't actually illegal, because there are some fones comming out on the market that have the Silver box tones built into a fourth row vertically, as they should be. No one really knows what the tones do, except that they are used in some military switching systems. There are rumors of the Bell companies comming out with features that would utilize this fourth row of keys. The Silver box utilizes the standard touch tone fone DTMF's, plus the tones listed below.: KEY: TONE A: 699.1 + 1633 B: 766.2 + 1633 C: 847.4 + 1633 D: 948.0 + 1633 BLUE BOX MF's Now we come to the tones that were a Phreak's most important tool, the Blue Box tones. These tones no longer work in most areas, due to he fact that the Bell companies got smart and have switched, or are switching, or are soon to switch to a newer system, ESS. Once again, if you don't know what that stands for, or what it is, see my file on and called: Bell Abbreviations by Damien.
