Silver Box Plans by the Jolly Roger
|
||
|
||
Introduction:
|
||
------------
|
||
First a bit of Phone Trivia. A standard telephone keypad has 12 buttons.
|
||
These buttons, when pushed, produce a combination of two tones. These tones
|
||
represent the row and column of the button you are pushing.
|
||
1 1 1
|
||
2 3 4
|
||
0 3 7
|
||
9 6 7
|
||
697 (1) (2) (3)
|
||
770 (4) (5) (6)
|
||
851 (7) (8) (9)
|
||
941 (*) (0) (#)
|
||
So (1) produces a tone of 697+1209, (2) produces a tone of 697+1336, etc.
|
||
|
||
Function:
|
||
--------
|
||
What the Silver Box does is just creates another column of buttons,
|
||
with the new tone of 1633. These buttons are called A, B, C, and D.
|
||
|
||
Usefulness:
|
||
----------
|
||
Anyone who knows anything about phreaking should know that in the
|
||
old days of phreaking, phreaks used hardware to have fun instead of other
|
||
people's Sprint and MCI codes. The most famous (and useful) was the good
|
||
ol' Blue Box. However, Ma Bell decided to fight back and now most phone systems
|
||
have protections against tone-emitting boxes. This makes boxing just
|
||
about futile in most areas of the United States (ie those areas with Crossbar
|
||
or Step-By-Step). If you live in or near a good-sized city, then your phone
|
||
system is probably up-to-date (ESS) and this box (and most others)
|
||
will be useless. However, if you live in the middle of nowhere (no offense
|
||
intended), you may find a use for this and other boxes.
|
||
|
||
Materials:
|
||
---------
|
||
1 Foot of Blue Wire
|
||
1 Foot of Grey Wire
|
||
1 Foot of Brown Wire
|
||
1 Small SPDT Switch (*)
|
||
1 Standard Ma Bell Phone
|
||
(*) SPDT = Single Pole/Double Throw
|
||
|
||
Tools:
|
||
-----
|
||
1 Soldering Iron
|
||
1 Flat-Tip Screwdriver
|
||
|
||
Procedure:
|
||
---------
|
||
(1) Loosen the two screws on the bottom of the phone and take the casinf off.
|
||
(2) Loosen the screws on the side of the keypad and remove the keypad from
|
||
the mounting bracket.
|
||
(3) Remove the plastic cover from the keypad.
|
||
(4) Turn the keypad so that *0# is facing you. Turn the keypad over. You'll see
|
||
a bunch of wires, contacts, two Black Coils, etc.
|
||
(5) Look at the Coil on the left. It will have five (5) Solder Contacts
|
||
facing you. Solder the Grey Wire to the fourth Contact Pole from the left.
|
||
(6) Solder the other end of the Grey Wire to the Left Pole of the SPDT Switch.
|
||
(7) Find the Three (3) Gold-Plated Contacts on the bottom edge of the keypad.
|
||
On the Left Contact, gently seperate the two touching Connectors (they're
|
||
soldered together) and spread them apart.
|
||
(8) Solder the Brown Wire to the Contact farthest from you, and solder the
|
||
other end to the Right Pole of the SPDT Switch.
|
||
(9) Solder the Blue Wire to the Closest Contact, and the other end to the
|
||
Center Pole of the SPDT Switch.<2E><>(10) Put the phone back together.
|
||
|
||
Using The Silver Box:
|
||
--------------------
|
||
What you have just done was installed a switch that will change
|
||
the 369# column into an ABCD column. For example, to dial a 'B', switch
|
||
to Silver Box Tones and hit '6'.
|
||
Noone is sure of the A, B, and C uses. However, in an area with an
|
||
old phone system, the 'D' button has an interesting effect. Dial Directory
|
||
Assistance and hold down 'D'. The phone will ring, and you
|
||
should get a pulsing tone. If you get a pissed-off operator, you have a
|
||
newer phone system with defenses against Silver Boxes.
|
||
At the pulsing tone, dial a 6 or 7. These are loop ends.
