- Anything you connect to the phone lines
- is *supposed* to be FCC registered, to
- make sure it won't 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, ith the
- phone company before connecting any
- stuff to your line. (These gadgets do
- not put n xr rnger 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. Yever pay
- to have an operator set them up for you
- again. Once you've called the two
- other pol nyu 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 von not
- in use, with higher pulses when
- ringing; around 10 volts when a phone
- is being used - ogtte exact
- numbers, but those are close.)
-
- The two lines can be connected through
- capacitors, so the audio passes between
- the two, but the DCes don't
- interfere with each other. (If you
- simply short the lines together, the
- phone comaymyntlike it!)
-
- Use this simple circuit:
-
- ! !
-
- red --------! !---o: o------ red
- ! ! :
- (line 1) : (line 2)
- ! !
-
- green--------! !---o o------green
- ! !
- ^ ^
- capacitors DPST
- .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'the
- capacitors.)

- HOLD BUTTON
-
- 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 mae line look
- screwed up to the phone company.
-
-
-
- red ------o o----\\\\------ green
-
- SPST 1-2K
- switch
-
- (It doesn't matter which direction you
- connect this circuit in -- red-to-green
- and green-to-red bo.)
-
- If you like, you can add an LED that
- will light whenever you have someone on
- hold. Just connect tin series
- with the switch and resistor (now about
- 500 ohms to 1.5k, depending on your LED
- - xeiet). Like this:
-
- ^^
- !\ !
- red -----o o----\\\\-----! >!--- green
- ! !
-
- SPST sw. .5-1.5K LED
-
- 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 switchined 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.
-

-
-
- Parts: 1 1.8k 1/2 watt resistor
- 1 1.5v LED
- 1 SPST switch
-
- You may just have two wires which you
- connect together for the switch.
-
-

- recommend using. It is neat and is
- very easy to hook up.

-
-
- 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!

- Silver Boxing
-
-
- 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
