          Little has been documented about the use of the silver box. Many 
assume a silver box is just a set of Autovon keys, or more advanced readers may
be familiar with its use in conjunction with the standard Directory Assistance
ACD (Automated Call Distributor which distributes the calls to the individual 
Directory Assistance operators) but in reality there are several applications 
to the hidden row than meets the eye.
 
          I will not explain the construction methods here, for they are widely
available on many telecom-oriented bulletin board systems, but rather go into 
detail about using them. 
 
The ACD and DA operators:
-------------------------

The ACD can be reached through calling a Directory Assistance operator and  
holding down the D key (941+1633 Hz) while the operator answers her console, 
the tone will trip the circut and drop you into the ACD.  One way to verify 
that you have tripped the circut is a Stutter-tone, or pulsing dialtone.  From
this prompt, you can dial up to 10 possible functions:
 
 
       1 - Rings the Toll Text board - Useful if you dont have the numbers on 
           file. 
 
       2 - Sometimes dead circut, other times milliwatt test.
 
       3 - Sometimes milliwatt test, others 1000/1004 Hz tone.
 
       4 - Usually dead circut
 
       5 - Always dead circut
 
       6 - Low end of loop - If your friend calls the ACD on the same op. as 
           you do, and dials 7, you are connected.
 
       7 - High end of loop.
 
       8 - 600 ohm termination
 
       9 - Usually dead circut
 
       0 - Usually dead circut
 
 
       Notes:  If you are having trouble with this method, try the 414 DA 
operator.  It never fails, but the dial tones will sound more like a busy 
signal than a dial tone.
 
       No 'Codes'?  Well, if your friend lives in the same state, arrange to
meet on the 800-555-1212 ACD (functions: 6,7.) 
 
Autovon Tone Set:
-----------------
  
The silver box keys also appear on the standard Autovon (the military phone 
network) keypad.

       The functions are as follows:
 
 
       A - Flash
 
       B - Flash Override (Priority)
 
       C - Priority Communication (dial)
 
       D - Priority Override (used to reach busy numbers in extreme emergen-
           cies.  When the tone is hit, I believe a flag is set as an emergency
           condition, and only for top military)
 
       To use the Autovon keys, scan for your local  Milnet or Autovon port. 

       All numbers are 7 digits (for those of you who insist on trying this,
please take the proper security measures.)
 
 
Centegram hacking:
------------------

Yes, your silver box can also be used for hacking earlier versions of 
Centegram.  While hacking the system administrators box and entering an invalid
code, the system will attempt to log you off, but hit 'C' and feast your ears
on 'Welcome to the message center...'  Another use in Centegram hacking is
when you are entering an auth. code, it will recognize A, B, C, and D as valid
digits for added security. 
 
 
       (Special thanks goes out to Phiber Optik for the help with ACD and Felix
the Hack for the Centegram information.)
