CLEAR BOX

------------ 
Introduction 
------------

A new device has just been  invented.   It's  called  the  "clear
box".   It can be used throughout Canada and through rural United
States.

This interesting gadget works on "post-pay" payphones,  in  other
words,  those  phones  that don't require payment until after the
connection has been established.  You pick up the  phone,  get  a
dial  tone,  and then put in your coins after the person answers.
If you don't deposit money, you can't speak to the person at  the
other  end, because your mouthpiece is cut off--but not your ear-
piece.  (Yes, you can make free calls to weather, etc. from  such
fones)

How to do it 
------------

In order to bypass this, all one has to  do  is  visit  a  nearby
electronics  store,  get a 4-transistor amplifier and a telephone
suction cup induction pick-up.  The induction  pick-up  would  be
hooked  up  as it normally would to record a conversation, except
that it would be plugged into the OUTPUT of the amplifier  and  a
microphone  would  be  hooked  to  the  input.  So when the party
answers, the caller could speak through the little microphone in-
stead.   His  voice  would then go through the amplifier, out the
induction coil, and into the back of the receiver where it  would
then  be  broadcast  through  the phone lines and the other party
would be able to hear the caller.  The clear box thus "clears" up
the problem of not being heard.

The line will not cut off after a certain amount of time--it will
wait forever for the coins to drop in.

Many independents are moving towards this kind of stupid payphone
system.   For  one  thing, it is a cheap way of getting DTF (Dial
Tone First) service.  It doesn't require any  special  equipment.
That  type  of  payphone  will  work on any kind of a phone line.
Normally a payphone line is different, but this is just a regular
phone  line  and it's set up so that the payphone does all of the
charging, not the CO.  With the recent deregulation of payphones,
this kind of a system could become very popular.
