PARTY BOX 
---------

By: Greyhawke of TDK



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

Ever wanted three-way calling  without  having  to  pay  for  it?
Wanted  to  connect  two phone conversations at once, without any
static or excess wiring, or even having two  phone  lines?   Ever
gone  beige  boxing  and wanted to connect two operators (or any-
one!) but didn't have the necessary stuff with  you?   The  party
box fixes them all!


--------- 
Materials 
---------

(1)     DPDT slide switch 
        (all you need is DPST, but DPDTs are easy to get) 
(2)     Modular phone jacks 
(4)     Alligator clips
        Some wire (doesn't matter what kind)


-------- 
Assembly 
--------

Take four lengths of wire, and strip the ends about 1/4" on  both
ends  of the wire.  Connect two wires to the red and green termi-
nals on one phone jack, and two wires to the red and green termi-
nals  on  the other phone jack (so you've used all four pieces of
wire).  Connect to the other ends of each wire a red or green al-
ligator  clip  (down at Radio Shack they sell some nice ones with
color coded insulator sleeves.  Get these,  it's  REAL  important
that  you  know  the  red  ends  from the green).  If you do this
right, you'll have a red and green aligator clip on each  of  the
two  phone  jacks,  connected  to  the  wires.  By this time, you
should not have any wire end loose; they should all be  connected
to SOMETHING.

Now, if you've been paying attention and  you  know  your  boxes,
you'll  recognize  the two pieces of equipment you've just assem-
bled as beige boxes. That's all they are, really, is beige boxes.

Here's what makes those two beige boxes into a single party  box.
Take  four  more short (like 1.5") lengths of wire, and strip all
the ends to about 1/4".  First connect one side of each wire to a
contact  on  the  DPDT  or  DPST switch.  Just make sure it's the
right switch.  For DPST, you won't have a problem, but for  DPDT,
make  sure the switch looks like this when the wires are connect-
ed:
                       *-**-* -
                       *-**-* -

It's doesn't really matter which side you connect the  wires  to,
just  make sure that at least two of them are in the middle.  The
wires are connected to the terminals surrounded by asteriks  (*).
Solder  each  connection  carefully  to make sure it's a good one
that won't fall off, and make sure none of the wires are touching
each  other!!   If they do you've got a short circuit and the box
won't work!

Here's the tricky part.  Take the bottom two  wires  (looking  at
the  DPDT switch from the bottom, so it looks like the above pic-
ture) and connect each one to  the  red  terminal  on  the  phone
jacks.   One wire to each jack.  Then, take the top two wires and
connect one to the green terminal on each phone jack. Again,  one
wire  to each jack.  Screw down all the terminals good and tight.
If you've done this correctly, there should be two wires  leading
to  each  red and green terminal on the two phone jacks.  Set the
switch so it's in the off position.  It's off when only the  mid-
dle terminals of the switch are covered, or so that the switch is
on the side where there aren't any wires coming to the  terminals
there.   Just  make sure it's in the beige mode.  Your box is now
built.

(This is if you used the jacks I suggested  at  the  top  of  the
file.)  To make it look pretty, you can cut away a portion of the
plastic surrounding one of the jacks so that the switch will  fit
nicely  in  the  place  you cut away. Also cut away a small half-
circle on the bottom of the surrounding plastic to feed the wires
out  of  (the ones with the alligator clips, not the ones leading
to the switch).  Once these two things are done, and  the  switch
is  screwed down securely, tape it all up, super-glue, who cares.
It doesn't matter; just so it stays together.

Once all this is done, here's a few things I like to do  to  make
things easy.  Put a small dot of white paint in the lower part of
the switch, so that when it's on the paint shows.  This  is  easy
to  do.   Also you might want to know which line you're using for
each box.  Just put a glob of a different colored paint  on  each
side  of the party box, and put the same color paint on the wires
leading out of that side of the box.


----- 
Usage 
-----

When used in beige box mode (so that the switch is off), the par-
ty  box will operate just like two beige boxes.  There are total-
ly, 100% separate from each other, and  the  conversations  don't
get crossed.

However, when used in the party box mode, the party box  connects
both  lines to each other, essentially connecting all four people
to the same line. Everyone can hear each other, and there is lit-
tle  or  no  static  created by doing this.  It's works great for
connecting anyone together, and all that's needed is  each  beige
box connected to an output device ("Bell Can"), and the switch in
the party mode position.  See a file on beige boxing for detained
info on what to do while boxing, etc, or how to connect to a Bell
Can.


---------
Schematic
---------

This is a really easy box, but someone might want a schematic, so
here's one:


<--- to one phone jack               to the other phone jack --->

--------------------------    __/   -----------------------------
(red [ring] wire)        - __/!     -           (red [ring] wire)
------------------------ O/   !_/   O ---------------------------
(green [tip] wire)     -   __/        -        (green [tip] wire)
                       - O/         O -
                       - -          - -
                       ---          ---


It's a really bad schematic, but the little things in the  middle
are  supposed  to  represent the switch in the off posistion, and
the exclamation points just mean it's a DPST switch that  doesn't
connect the top and the bottom termials.  The (-) and the (-) are
supposed to be the wire.
