SILVER BOX 
----------



------- 
History 
-------

Well, now that I have you hare, I might as well bore you  with  a
little  history of the Silver Boxes.  One day, some engineer over
at Bell Labs got the bright idea to sing  to  his  computer...and
found  out that the computer responded by dialing a phone number.
Well, sort of.  Anyway, the 10 digit (old style with the # and  *
left out) was born.

Lo and behold, though, two sets of people decided that 10 (or 12)
buttons just weren't enough...they needed more. The two people of
whom I am speaking of are of course MA BELL and PA  AUTOVON  (The
Military Phone Network). So, MA decided to add an extra column to
her phones, this one merging the standard row tones with  a  1633
HZ tone (to provide the mystical DTMF).  Bell named these buttons
A,B,C and D (aren't you glad we have such imaginative  friends at
our  Bull  System?),   while  the Army named them FLASH OVERRIDE,
FLASH, INTERRUPT AND PRIORITY. These are used  to request varying
degrees  of  priority  during wartime (and wargame) activities so
that generals can call their secretaries  very  quickly.   Bell's
use of ABC and D is not so clear.

However, the last button (D)  has  an  interesting  property...on
about  50%  of the information lines in the country, it will give
you a pulsing dial tone.  You can then enter commands  that  what
appear  to be a test system for the 4A switching boxes.   Anyway,
the modification...


--------- 
Materials 
---------

Soldering Iron 
Solder Some  
22  ga.wire  
1  SPDT  switch
a screwdriver



------------ 
Construction 
------------

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 (red) wire to the other  one,
   a (yellow) wire.

10) Run the 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.

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 override (top military)



----- 
Usage 
-----

Those keys only work on certain networks.  Now  what  do  you  do
with those extra tones? Call any long distance directory by dial-
ing (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.  414 A/C is good for
one  that.   You can screw around with the tones and see what you
get.

Note: You will not receive a pulsing tone until the operator  ac-
tually  picks  up  on the line.  If you hear ringing on the back-
ground, keep pressing.  The tone must be on at the same time  the
operator gives her "beep".

If you  hear her  cursing at stupid people  with  stuck  buttons,
chances  are this one won't work...try out of the way states like
Montana, Wyoming, etc.

Happy phreaking...
