- Part I
-
- -------------------------------------
-
- AUTOVON is the Military Voice Communications System. Each Military
- Installation has it's own prefix for use in the AUTOVON system. Not all
- telephones on military installation have the capability to call another
- military installation via AUTOVON. However, they can all receive an AUTOVON
- call coming from another installation.
- A different 3-number prefix is used when dialing a military base using
- AUTOVON than the prefix used when dialing through the civilian phone system.
- Usually, AUTOVON is accessed by dialing 8 or 88 and waiting for a dial tone(on
- any phone connected to the AUTOVON system). A phone call made in this manner is
- limited to "ROUTINE" Priority.
- There are "ROUTINE","IMMEDIATE", "FLASH", and "FLASH OVERRIDE" priorities,
- with ROUTINE being the lowest and FLASH OVERRIDE the highest To dial higher
- priority phone calls than routine, access to Technical control equipment is
- normally needed.
- Calling AUTOVON exchanges might (most likely will) need a small phone
- modification. This modification is known as a "SILVER BOX".
- Further inphormation on SILVER BOXES will be described in part II. Stay
- tuned...

- Warning: This modification could permanently damage you phone!! Read
- information carefully!!!
-
- Step One: Unscrew the two large screws on the base of your phone. Take
- cover off and place it and the screws in a safe place.
- Loosen (but don't remove) the screws on the sides of the touch tone keypad
- (These are on the sides, and attach it to its mounting brackets). Now,
- CAREFULLY remove the pad from its brackets (be sure not to trip any wires!!)
- You will notice a plastic cover on the pad. Separate the two halves and put
- them out of your way... Be sure not to destroy them!!!!
- Now, turn over the pad. You should see a mass of wires, gold plated
- contacts( yea, it's real gold!), discrete components, and two fairly large
- black, hmmm, things!
- These are the coils that generate the frequencies. Only one is used for
- standard, so all the coils are capable of generating all 4 primary tones
- (only connections to 3 of the 4 are given, though...). Your about to make
- your connection to the fourth, and make the third column of keys "bank
- switched" between normal and fourth row.
- Now, cut three lengths of wire of different colors about 2 feet long. Look
- at the coil on the left (with the 5 solder contacts facing you) and solder a
- wire to the to the 4th post from the left. This is the 1633 Hz output. Solder
- the other end of this wire to the left pole of the smallest SPDT switch you
- can find. This is the point of no return now!!!!..Take a look at the bottom
- edge of the keypad. You should see a row of 3 gold plated contacts. Look at
- the one on the left. This controls the rightmost bank of keys.
- GENTLY separate the two touching connectors (they are soldered together with
- a drop of solder with) and spread them apart. Solder a colored wire to the
- top contact, and solder it to the RIGHT pole of the SPDT.
- Now, take another colored wire (different color) and solder it to the bottom
- (closest) contact. Solder the other end of this to the CENTER pole of the
- SPDT.
-
- You have now completed the mods on your phone!!! Congrats!!!
- When the switch is in one position you'll get normal tones, in the other
- you'll get 1633 tones.
- Operating procedures will be described in the next phile... Stay tuned!!!

-
- Now, you're at the part that you have been waiting for!! Testing!! Call
- Directory Assistance using normal tones xxx-555-1212. Now, quickly switch to
- 1633, and press down the [#] key. You will now get a dial tone. You can then
- switch back to normal, and try dialing different numbers. The two most
- interesting are 6 and 7. These often form a loop-around type connection, and
- two people can call in, one using 6 and one using 7, and talk in this
- matter...
- Happy Phreaking you bad boys!!
