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 person will sound 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.

|_____PHONE____|
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 any-
thing in the phone or telephone by probing. 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. /
