(>Introduction<)

This is a fairly simple modification that can be made to any phone. All it
does is allow you to take any 2 lines in your house and create a party
line. So far I have not heard of Any problems with it from my friends that
have set one up and I have not had any either. There is one thing that you
will notice when you are one of the two people who is called by a person
with this box. The other person0will sount a little bit faint.  I could
overcome this with some amplifiers but then there wouldn't be very many of
these boxes made.

I think that the convenience of having two people on line at any one time
will make up for the minor volume loss.

In some houses the black and yellow are already wired in others you will
have to go out to your box and rewire it. A good way to figure out which
line is which is to take the phone you are looking for off the hook.  Then
you only need to take the red and green wires entering your phone and hook
them to the different pairs of red and green going into the house.  You
can't hurt anything in the phone or telephone by probeing.  When you find
the pair that you want take the black from your line and attach it to the
red of the other line then take the yellow and attach it to the green
line.  Now you are all set to go.  For people with rotary phones you can
have one person call you then place the second call out to the other
person. Though not a phreakers tool, the brown box can be phun.
