Anything you connect to the phone lines is *supposed* to be FCC registered, to
|
|
make sure it won't injure repairmen or damage equipment. The gadgets des-
|
|
cribed in this file do NOT apply any extra voltage to the line, and should
|
|
be safe. If in doubt, check with the phone company before connecting any
|
|
stuff to your line. (These gadgets do not put any extra "ringer equivalence"
|
|
on your line, either.)

CONFERENCE CALLER
|
|
|
|
If you have two phone lines, you can this simple attachment to set up your
|
|
own conference calls. You'll never pay to have an operator set them up for
|
|
you again. Once you've called the two other people on your two lines, you
|
|
just throw the switch. All three of you can now talk to each other.
|
|
|
|
Phone lines carry voices as audio frequencies superimposed on DC control
|
|
voltages (around 40-50 volts when not in use, with higher pulses when
|
|
ringing; around 10 volts when a phone is being used -- I forget the exact
|
|
numbers, but those are close.)
|
|
|
|
The two lines can be connected through capacitors, so the audio passes between
|
|
the two, but the DC voltages don't interfere with each other. (If you
|
|
simply short the lines together, the phone company may not like it!)
|
|
|
|
Use this simple circuit:
|
|
|
|

|
|

|
.1 to 1 uf switch
|
|
(not critical)
|
|
(do *not* use polarized electrolytics!)
|
|
|
|
(This circuit is similar to the other conference caller mentioned on the
|
|
Roman Forum, which doesn't have the capacitors.)

This gadget also is a variation on one posted on the Roman Forum.
|
|
|
|
Shorting the line is not a good idea. A resistance of 1-2K is enough to hold
|
|
the line, without making the line look screwed up to the phone company.

|
|
(It doesn't matter which direction you connect this circuit in -- red-to-green
|
|
and green-to-red both work.)
|
|
|
|
If you like, you can add an LED that will light whenever you have someone on
|
|
hold. Just connect the LED in series with the switch and resistor (now about
|
|
500 ohms to 1.5k, depending on your LED -- experiment!). Like this:

This circuit (with the LED) only works if it's connected in the right direc-
|
|
tion. Phone wiring isn't always done right; before you wire this one in
|
|
permanently, try switching the red and green wires, and leave it in the
|
|
direction that works.
|
|
|

|
|
ENJOY!

* How to build a BLACK BOX *
|
|
* *
|
|
***************************************
|
|
|
|
To all who dare --
|
|
|
|
What is a BLACK BOX? A BLACK BOX is a device that is hooked up to your
|
|
fone that fixes your fone so that when you get a call, the caller doesn't get
|
|
charged for the call. This is good for calls up to 1/2 hour, after 1/2 hour
|
|
the Fone Co. gets suspicious, and then you can guess what happens.
|
|
|
|
The way it works:
|
|
|
|
What this little beauty does is keep the line voltage from dropping to
|
|
10v when you answer your fone. The line is insted kept at 36v and it will
|
|
make the fone think that it is still ringing while your talking. The reason
|
|
for the 1/2 hour time limit is that the Fone CO. thinks that something is wrong
|
|
after 1/2 an hour of ringing.
|
|
|
|
All parts are available Radio Shack. Using the least possible parts
|
|
and arangement, the cost is $0.98 !!!! And that is parts for two of them!
|
|
Talk about a deal! If you want to splurge then you can get a small PC
|
|
board, and a switch. There are two schematics for this box, one is for
|
|
most normal fones. The second one is for fones that don't work with the
|
|
first. It was made for use with a Bell Trimline touch tone fone.

Once you have hooked up all the parts, you must figure out what set of
|
|
wires go to the line and which go to the fone. This is because of the fact
|
|
that LED's must be put in, in a certain direction. Depending on which way you
|
|
put the LED is what controls what wires are for the line & fone.
|
|
|
|
How to find out:
|
|
|
|
Hook up the box in one direction using one set of wires for line and the
|
|
other for fone.
|
|
|
|
*NOTE* For Model I switch should be OFF.
|
|
*NOTE* For Model ][ switch should be set to side connecting the led.
|
|
|
|
Once you have hooked it up, then pick up the fone and see if the LED is
|
|
on. If it is, the LED will be lit. If is doesn't light then switch the wires
|
|
and try again. Once you know which are which then label them. *NOTE* - If
|
|
neither directions worked then your switch was in the wrong position. Now
|
|
lable the switch in its current position as BOX ON.
|
|
|
|
How to use it:
|
|
|
|
The purpose of this box is not to poeple who call you so it would make
|
|
sence that it can only be used to receive! calls. When the box is *ON*
|
|
then you may only recieve calls. Your fone will ring like normal and the LED
|
|
on the box will flash. If you answer the fone now, then the LED will
|
|
light and the caller will not be charged. Hang up the fone after you are done
|
|
talking like normal. You will not be able to get a dial-tone or call when
|
|
the box is on, so turn the box *OFF* for normal calls. I don't recommend
|
|
that you leave it on all the time, as you don't want it to answer when Ma
|
|
Bell calls!

How to build a SILVER box:
|
|
|
|
|
|
Tools and materials : Soldering Iron, Solder,
|
|
Some 22 ga. wire, a SPDT switch, and a screwdriver.
|
|
|
|
|
|
1) Unscrew your phone (must be a touch tone, desk type)
|
|
2) Remove the mounted pad and take the clear plastic cover from the bottom.
|
|
3) Hold the pad with the numbers 0, *, # facing you, and turn it upside down,
|
|
so you can see the yellow pc board.
|
|
4) You should see 2 black round doughnuts.
|
|
5) Position the board so the solder points for the left doughnut face you.
|
|
6) Count over four points from the left, and attach a (green) wire to that
|
|
point.
|
|
7) Between you and the doughnuts, there should be 2 long yellow capacitors.
|
|
To the right of these, and on the edge of the board there should be 3 gold
|
|
contacts. We will use the one on the left.
|
|
8) The bontact originally is spot welded, so snip it open.
|
|
9) To the one nearest you, attach a (red) wire to the other one, a (yellow)
|
|
wire.
|
|
10) Run the wires out of the phone, and solder the switch.
|
|
11) The orientation should be (red) to center.
|
|
|
|
The switch will now alternate between normal and 1633hz fourth column tones.

HOW TO BUILD A HOLD BUTTON
|
|
|
|
I WILL DO THIS STEP BY STEP:
|
|
|
|
1. YOU CAN EITHER DO THIS FROM THE
|
|
OUTSIDE OR FROM THE INSIDE OF
|
|
YOUR PHONE. FIRST TAKE THE RED
|
|
AND GREEN WIRES AND STRIP DOWN
|
|
A PIECE OF WIRE SO YOU CAN ADD
|
|
ANOTHER PIECE OF WIRE TO IT.
|
|
|
|
2. ONCE YOU HAVE THE OTHER PIECE'S
|
|
OF WIRE ADDED TO THEM GET A
|
|
A TWO WAY TOGGLE SWITCH SO THAT
|
|
YOU CAN SWITCH THEM FROM HOLD TO
|
|
TALK POSITION
|
|
|
|
3. TAKE THE TWO EXTRA PIECES OF
|
|
WIRE AND HOOK THE ONE THAT IS
|
|
HOOKED TO THE GREEN TO ONE OF
|
|
THE TERMINALS ON ONE SIDE AND
|
|
THE RED WIRE TO THE OTHER SIDE
|
|
OF THE TERMINAL
|
|
|
|
DIAGRAM:
|
|
|
|
RED GREEN
|
|
|
|
BLACK YELLOW
|
|
|
|
LEAVE THE RED AND GREEN HOOKED TO THERE TERMINALS IN THE BOX BUT JUST
|
|
RUN A WIRE FROM EACH OF THOSE TERMINALS AND HOOK ONE WIRE TO ONE
|
|
SIDE OF THE SWITCH AND THE OTHER WIRE TO THE OTHER SIDE OF THE SWITCH
