The Extension Silencer
|
||
|
||
By Terrance Kelly
|
||
|
||
This project keeps your modem communications and important private
|
||
conversations from being interrupted by locking out extension phones when the
|
||
line is in use.
|
||
|
||
Are you tired of others listening in on your conversation on an extension
|
||
phone? Do you live with a computer hacker who always seems to want to dial out
|
||
with his modem in the middle of your of your conversations? Fear no more,
|
||
three inexpensive parts - which comprise the Extension Silencer - will solve
|
||
all of your problems.
|
||
|
||
The Extension Silencer described in this article is a simple is a simple
|
||
circuit that, when placed in series with each of your extension telephones,
|
||
allows privacy at each location without interference from the others. All
|
||
phones will ring normally and the first one to answer locks out the others.
|
||
Someone picking up an extension will hear nothing if the phone is already in
|
||
use. If you need to switch extension all you have to do is pick up one
|
||
extension and hang up the other.
|
||
|
||
In order to fully understand the operation of the Extension Silencer, a
|
||
little discussion on telephone operation is in order.
|
||
|
||
Telephone Operation
|
||
|
||
Each subscriber telephone is connected in what's called a local loop to
|
||
central office, which contains switching equipment, signalling equipment, and a
|
||
power source that supplies direct current (DC) for the operation of the
|
||
telephone system within its coverage area.
|
||
|
||
Switches in the central office respond to string of dial pulses to connect
|
||
the calling station with the station being called. The Switching array within
|
||
the central office feeds an AC ring signal down the line to the station being
|
||
called. When a link is established (the telephone receiver is taken off-hook),
|
||
the two stations communicate via transformer-coupled loops using DC power
|
||
supplied by the central office.
|
||
|
||
When the telephone receiver is on-hook, the receiver holds down the
|
||
hook-switch buttons in the base of the unit, creating an open circuit to DC
|
||
between the receiver and the central office. The signaling circuit, which is
|
||
AX operated, is always connected to the central office; a capacitor in the
|
||
signaling circuit blocks the flow of DC, while passing the AC ring signal.
|
||
|
||
As long as the hook-switch buttons on the telephone are depressed, no
|
||
communications can take place. However, when the receiver is taken off-hook,
|
||
the hook-switch closes contacts, passing DC to the telephone, activating the
|
||
communications circuits, and causing the normal DC line voltage to drop due to
|
||
the loading effect of the telephone.
|
||
|
||
Circuit Operation
|
||
|
||
The circuit is little more than an electronic cut-off switch built around a
|
||
Triac (the switching element). Two phone station, A and B, are show to make
|
||
the circuit's operation easy to understand (Component designations for only one
|
||
circuit are given in the Parts List). Note that an Extension Silencer circuit
|
||
is connected in series with each station.
|
||
|
||
Normally when a phone is on hook, the voltage across the phone line is
|
||
48-volts DC; when the receiver is taken off hook (is picked up), the DC voltage
|
||
across the line drops to between 2 and 12 volts DC (typically about eight
|
||
volts). That's due to the off-hook impedance of the telephone and the loop
|
||
resistance between the subscriber station and the telephone company's central
|
||
office.
|
||
|
||
As long as both Station A and Station B receivers are on-hook, the voltage
|
||
at the gates of TR1 and TR2 is sufficient to trigger TR1 and TR2 into
|
||
conduction. That means that both Extension Silencer circuits connected to that
|
||
line are conducting. But when one of the receivers - say station A - is lifted
|
||
from it's cradle, closing the hood-switch contacts, that telephone draws
|
||
considerably more power, causing the line voltage at TR2 to drop to around
|
||
0.6-volt DC.
|
||
|
||
The operational characteristics of the Triac are key to the operation of
|
||
the Extension Silencer circuit. Remember that once a Triac is triggered (via a
|
||
gate trigger voltage), it continues to conduct as long as the current through
|
||
it remains above it holding-current requirement, even if the trigger source is
|
||
removed. And will cease to conduct, only when the current through the device
|
||
is brought below its holding-current level. (In the case of an AC signal, a
|
||
Triac would be triggered into conduction twice during a single cycle: once
|
||
during the positive half-cycle, and again during the negative half-cycle.
|
||
Therefore the 20-Hz ring signal is passed to the phone uninhibited.)
|
||
|
||
The 0.6-volt level at the main terminals of TR2 is too small to generate
|
||
sufficient current through TR2 to satisfy it's holding-current requirement, so
|
||
it turns off, disallowing any communications through station B.
|
||
|
||
If the station B extension is take off-hook and station A is hung up, a
|
||
similar, but reversed action occurs, with station B absorbing the majority of
|
||
the line-fed power, reducing the current through TR1 to a level insufficient to
|
||
sustain conduction through that unit. And that in turn locks out Station A.
|
||
|
||
A 15-volt Zener diode was used because that is all the local Radio Shack
|
||
had in stock, but anything between 12 and 24 volts would have done just fine.
|
||
The value specified for R1 (1000-ohms) was chosen to yield 35 mA of Zener
|
||
current. That amount of Zener current may seem excessive, but keep in mind
|
||
that it is on for a very short time. before a call is answered there is no
|
||
loop current because the phone-hook switch is open, so there is no Zener
|
||
current.
|
||
|
||
Construction
|
||
|
||
There is nothing critical about the construction of the Extension Silencer.
|
||
In fact the author's prototype of the circuit was assembled on a small section
|
||
of perfboard - half of Radio Shack's 276-148 snap-apart perfboard - measuring
|
||
about 1 3/4 inches square. The circuit-board assembly was then housed in a
|
||
modular quick-connect phone-jack cover.
|
||
|
||
Before assembling any components on the board, the two sections must be
|
||
separated and a hole drilled (through the center of the board) for a wood screw.
|
||
The wood screw will be used for mounting the assembly to the wall. Next,
|
||
solder the three parts onto the perfboard, interconnecting the components as
|
||
they are installed.
|
||
|
||
Cut the black and yellow leads from the modular jack as they will not be
|
||
used. Solder the red and green leads to the Extension Silencer perfboard since
|
||
all telephones use the center two conduction of the six position jack. Take
|
||
another short twisted pair of wires and solder them to the board for the phone
|
||
line. Observe the proper polarity of those wires because the one that attaches
|
||
to the red wire of the modular jack must connect to the minus terminal of the
|
||
phone line.
|
||
|
||
Installation
|
||
|
||
WARNING: Remember that all equipment installed on the telephone line must
|
||
meet FCC part 68 requirements. The equipment must be certified by an
|
||
authorized agent before it is used on the network. (This article is meant to
|
||
be of instructional value and not as a certification for FCC approval.)
|
||
|
||
Since my house had phone jacks with screw terminals inside all I had to do
|
||
was remove the face-plate and measure the voltage across the connection-block
|
||
terminals. The connection block has four screw terminals labeled L1-L4. In
|
||
most cases, the terminals of the connection block are tied to the telephone
|
||
line via a quad color-coded cable - red, green, yellow, and black. (Older
|
||
installations use twisted twin lead tied into the telephone line.) Normally,
|
||
the read and green wires are used as the communications pair, and are connected
|
||
to the L1 and L2 terminals.
|
||
|
||
With my VOM, I determined the polarity of the phone line. If the positive
|
||
lead of the meter is on L1 and the negative lead is on L2 and the meter reads a
|
||
positive 48-volts DC, then L1 is positive with respect to L2. If it reads
|
||
negative, then L2 is positive with respect to L1. In my own installation, the
|
||
minus lead was attached in parallel with the L2 terminal (you may find it to be
|
||
the L1 terminal) on the phone jack.
|
||
|
||
The plus terminal was then connected in parallel with the L1 Lead. Remove
|
||
the phone from the normal hack and insert its plug into the Extension Silencer
|
||
jack, and you are ready to go. Pick up the phone with the silencer and listen
|
||
for dial tone and hang up. Pick up the extension without the silencer and
|
||
leave it off hook.
|
||
|
||
Pick up the phone with the silencer and it should be "dead". Hang up the
|
||
phone without the silencer and there should be audio from the "dead" phone.
|
||
You can now add as many Extension Silencers as you have phones. For those
|
||
readers who have a "smart modem", set it to return "NO DIALTONE" if the line is
|
||
in use. Also set it to keep retrying so that you can capture the line should
|
||
it ever become free.

The Tele Monitor
|
||
|
||
By Charles R. Ball Jr. And W.K. Ball
|
||
|
||
Now you can keep an audible record of your telephone conversations with the
|
||
aid of this simple circuit.
|
||
|
||
WARNING: The use off the Tele Monitor and the parts therein is governed by
|
||
Federal and State law. Federal law prohibits the taping of telephone
|
||
conversation by one party without the knowledge and/or consent of the other
|
||
party. Many states have adopted identical or similar provisions. Prospective
|
||
users are advised to obtain independent advice as to the propriety of the
|
||
purchase and use of the parts and use of the Tele Monitor, including (but not
|
||
limited to) taping conversations therewith. We make no representations
|
||
concerning the parts referred to in this article of their use or the legality
|
||
of the use of the Tele Monitor, or any other such equipment referred to in this
|
||
article. Readers are advised to obtain independent advice as to the propriety
|
||
of their use of the parts, the Tele Monitor, or similar equipment based on
|
||
their individual circumstances and jurisdiction.
|
||
|
||
Remember when your sister called to tell you about this year's family
|
||
reunion, but in the excitement of hearing from her, you forgot to write down
|
||
the date, time, or even the city? How often have you talked on the phone with
|
||
a client for an extended period and after hanging up, remembered that you hadn't taken any notes?
|
||
|
||
Well, such memory lapses need not be a problem if you build the Tele
|
||
Monitor described in this article. The Tele Monitor automatically activates a
|
||
recorder to keep a perpetual log (within the limits of the tape's capacity) of
|
||
all call, incoming or outgoing. Best of all, it can be built for less than
|
||
$25, excluding the recorder.
|
||
|
||
How It Works
|
||
|
||
The circuit is connected between the telephone line and the tape recorder.
|
||
The telephone line - the conductors are designated tip and ring - normally has
|
||
-48 volts across it when the telephone is on hook. When the telephone is off
|
||
hook, that voltage changes to about -10 volts, depending on the subscriber loop
|
||
resistance.
|
||
|
||
A full-wave bridge rectifier (consisting of D1 through D4) connected across
|
||
tip and ring allows the circuit to be tied to the telephone line without regard
|
||
to polarity. The voltage applied across tip and ring appears, polarity
|
||
corrected, at the + and - ends of the diode bridge. When the phone is on hook,
|
||
the voltage through D5 keeps Q1 on and Q2 off, so the recorder is in an idle
|
||
state.
|
||
|
||
When any telephone tied to the circuit is picked up (an goes off-hook), the
|
||
voltage across tip and ring drops to about -10 volts, causing Q1 to turn off
|
||
and Q2 to turn on, activating the recorder through J2. Incoming calls also
|
||
activate the recorder with each ringing cycle.
|
||
|
||
When the phone is off-hook and the recorder is running, voice is coupled
|
||
through R1 and the C1/C2 combination. Because the central-office ringing
|
||
voltage is 105-volts AC, C1 and C2 - which must have a voltage rating of
|
||
150-volts or better - are connected back-to-back to simulate a non-polarized
|
||
capacitor. The diodes, D1 through D4, should have a peak inverse-voltage (PIV)
|
||
rating 200 volts of better.
|
||
|
||
Power for Tele Monitor is derived from the telephone line. A very small
|
||
current (less than 80uA) is derived from the telephone line through the diode
|
||
bridge when the phone is on-hook, so that Q1 remains off, keeping the recorder
|
||
is an idle state. (CAUTION: For use in this application, the recorder must be
|
||
battery operated or powered with a UL/CSA/FCC approved adapter. Nether the
|
||
telephone company or the FCC take kindly to having 120-volts AC suddenly appear
|
||
on the telephone line.)
|
||
|
||
It is recommended that the Tele Monitor circuit be coupled to a recorder
|
||
with automatic volume control to compensate for varying signal levels on
|
||
different calls and varying speech characteristics. The recorder mentioned in
|
||
the Parts List is one such recorder. Other recorders can be used, but you must
|
||
be sure that the internal remote-jack connections have the proper polarity for
|
||
Q2 to turn on the recorder.
|
||
|
||
Assembly
|
||
|
||
The author's prototype of the Tele monitor was assembled on a printed
|
||
circuit board measuring about 2 3/4 X 2 1/4 inches. The layout provides for
|
||
two modular connectors that allow you to connect your phone and the Tele Monitor to the same wall jack.
|
||
|
||
Once you have obtained or etched the board and are in possession of all the
|
||
components, begin assembling the project using the project. When stuffing the
|
||
board, be careful of component orientations, particularly the diodes,
|
||
capacitors, and transistors. Transistor Q2 should be heat sinked because the
|
||
combination of the saturation drop in Q2 and motor current in the recorder may
|
||
exceed the transistor's ambient thermal rating. Usually a small clip-on heat
|
||
sink is adequate.
|
||
|
||
Next, prepare a cable for connection to the remote jack of the recorder.
|
||
Select a plug that's suitable for mating with the remote jack of your recorder.
|
||
almost any wire will do, but for ease of soldering to the plug, 24 to 26 gauge
|
||
stranded wire is recommended. Make sure that the circuit-board pad marked "T"
|
||
is connected to the "tip" of the remote plug and and "R" to the other lug of
|
||
the plug.
|
||
|
||
After soldering the wires to the plug, twisting the wires about 2 turns per
|
||
inch will prevent the cable from tangling. If you are using a recorder other
|
||
than the once listed, check the recorder schematic to ensure that the circuit
|
||
is properly connected to the recorder.
|
||
|
||
Next, prepare a cable for connection to the mike jack. Again, you must
|
||
select a plug that's suitable for mating with the jack of your recorder. The
|
||
use of shielded audio cable is recommended. Solder the prepared cable to the
|
||
appropriate circuit-board pads.
|
||
|
||
Once the board is assembled and the cables connected, clean the flux from
|
||
the board, especially in the area of the modular connectors. Solder flux, when
|
||
damp, is conductive and can cause erratic operation. Also check for
|
||
misoriented or misplaced components, solder bridges, cold solder joints, and
|
||
all the other construction errors common to hobby electronic projects.
|
||
|
||
You must also prepare or purchase modular plug-to-plug telephone cable
|
||
(both ends terminated in modular plugs), which will be used to connect the
|
||
circuit to the telephone line. Radio Shack sells them in varying lengths, with
|
||
either coiled and flat cable. If a cable of greater length than is available
|
||
is needed, it will be necessary to make your own. All of the equipment and
|
||
material needed to handle that task is available from Radio Shack as well.
|
||
|
||
Preparing the Enclosure
|
||
|
||
A circuit is required for the modular telephone sockets, SO1 and SO2. Two
|
||
cutouts can be made (one for each socket), or a single long one, as shown. A
|
||
nibbling tool, available at electronic stores, is ideal for performing the
|
||
task.
|
||
|
||
Make sure that you check the orientation of the board before making the
|
||
cutout; the enclosure has only two posts for mounting the board. Position the
|
||
board, component-side down with the two mounting holes lining up with the
|
||
mounting posts to determine which part of the enclosure to cut.
|
||
|
||
Next, drill two holes for the recorder remote and mike cables. A 3/8-inch
|
||
hole for each will be adequate. It is recommended, however, that a 3/16-inch
|
||
hole be drilled and reamer used to enlarge the hole to the desired size.
|
||
Plastic is tricky to drill, and some plastics drill easier than others. The
|
||
plastic used to make the enclosure listed in the Parts List will chip, crack,
|
||
grab, or self destruct if you use large size bits. Drill speed is also
|
||
important; generally, the slower the drill sped the better.
|
||
|
||
Checkout
|
||
|
||
There are a number of ways to check out the circuit. First, check the
|
||
orientation of each component against the diagram and check all solder joints.
|
||
|
||
If you have a power supply capable of providing at least 50-volts DC, you
|
||
can check the Tele Monitor without connecting it to the telephone line. Attach
|
||
the power supply leads to the tip and ring leads of the modular sockets.
|
||
Connect J2 to the remote jack of the recorder. Press record and play as you
|
||
normally would to record. With the 50-volts DC power supply on, the recorder
|
||
should be "off;" with the supply off, the recorder should be running.
|
||
|
||
If you don't have access to be a 50-volts DC supply, it will be necessary
|
||
to use the telephone line as your power source. As before, connect the circuit
|
||
to the recorder. Install one of the modular plug-to-plug cable in one of the
|
||
Tele Monitor sockets and the other end in the wall. Either connect a phone to
|
||
the Tele Monitor or use another phone on the same line for the following test.
|
||
|
||
Pick up the telephone. The recorder should start; press "1" on the
|
||
telephone to eliminate the dial tone, and speak a few words into the mouthpiece
