Wired telephone connection diagram. How to connect telephone sockets to the cable correctly? Scheme and features. How to connect a phone to a communication line. Stage # 3: Connecting the outlet wires

To some extent, many phone users are familiar with the device. Almost everyone today has a cell phone, but the era of landline telephones is still not over. Unfortunately, it is impossible to connect it without installing an outlet. Any owner can install it on their own, and at the same time it will be useful to spy on the instructions for installing a telephone socket with your own hands.

Design of telephone sockets

Disregarding some of the design features and connection options, the telephone socket includes the following:

body - made of dialectic materials, for example, ceramics or plastics;
contacts made of springy brass, thanks to which an easy passage of electric current through this circuit is carried out;
terminals or special clamps - used to connect contacts.

All contact sockets are located inside the case, for safety in case of a short circuit. There are models with one or more connectors, respectively, to connect the required number of devices. You can see the models by the presented photos of telephone sockets.

How does one outlet differ from another?

The main classification of structures depends on the installation method: external and internal devices. Further, one and the other type are distinguished by the number of connectors: single-connector and multi-connector models.

Several years ago, there was not a wide variety of types of telephone sockets, since only one was used - RTShK-4. Today they are being replaced by the common European variants - RJ-11 and RJ-12.

The first option is suitable for residential buildings or apartments and has 2 contacts. The second type includes 4 wires, which is convenient, for example, for an office where more channels are needed. If you are going to mount an outlet at home, RJ-11 is a good solution.

There are other models - RJ-14 also has 4 contacts and conductors, it is considered a universal device, suitable for many devices. RJ-25 has 3 pairs of contacts. It is rather difficult to install on your own. RJ-9 is another type of connection that is responsible for connecting the handset of the phone and the device itself.

The choice of the best telephone socket is determined depending on the application, be it a private house, an apartment or a telephone line intended for a large company (office). All these nuances should be considered when choosing.

Detailed instructions for installing a telephone socket

Let's consider the basic diagrams for the correct connection of common sockets:

The design has a paired number of small contacts - 2 or 4. There is a hole for the power cable in the middle.
The telephone device connects to two contacts in the center.

Installation, according to the rules, is usually done using a special cross-cutter. But if your activity is not related to the systematic repair and installation of these devices and you do not have it available, you can use an ordinary sharp knife. It is used for burying the cores to ensure contact after cutting the insulation layer.

If you use an internal gasket, experts advise you to choose a KSPV cable, since it consists of copper wiring covered with white plastic. The TRP cable acts as a distributor.

To connect wires to the telephone socket, use the following instructions:

As well as during the installation of any outlet, you should turn off the power supply in the control room. For safety, use protective gloves, as there is still voltage.
Next, the outer layers of the contacts are cleaned, you can leave no more than 4 cm. When these manipulations are made, straighten the veins.
Use a tester to determine the polarity of the contacts.
Connect the pins to the conductors. It is convenient to distinguish them by their colors. The green wire is responsible for positive polarity, red for negative polarity. It is not necessary to focus on polarity, but there is a possibility that the phone may experience slight interruptions in the future.
After connecting the cables, fix them with the screws provided.
In the case of mounting a 2-4 pin socket type, the 2 center pins are connected.
Installation of the socket to the wall is done with double-sided tape or self-tapping screws. The latter method will provide a more efficient fixation method.
Completion of the installation process - close the telephone socket cover.

A hidden socket is connected according to a similar principle, while there are a number of features. Select a location and mark it for future installation. You will need a recess for the socket, so use a punch and self-tapping screws for fasteners. The working part is fixed in the socket with screws.

Pinout of telephone sockets

Consider the pinout (pinout) diagram of the contacts on the RJ-11 and RJ-45 connectors. As previously mentioned, telephone wall jack power has 2-4 pins and focuses on the two middle jacks. By standard, the telephone cable connects to the red and green cable in the socket, and the kit also includes a yellow and black cable. Green and black wire - means plus, red and yellow - minus.

As for the socket for computer communication, it is somewhat different from the telephone one, although they are similar in appearance. The cable for the Internet consists of 8 wires, twisted in twos. The output is 4 twisted pairs, which differ in color.

Distinguish between single, double, triple, internal and external. RJ-45 single is the simplest of the types, but double RJ-45 is considered to be universal. The cable is installed both in the wall and in the skirting board.

Switching does not require much effort or knowledge. All terminals are distinguishable by color, each of them is connected to the corresponding core color. It is important to follow the color scheme when pinouting RJ-45. It is enough just to combine them with each other. It is suitable for connecting a computer, TV, router.

The pinout should be done carefully without damaging the wires. The first thing to do is cut off the winding, leaving about 5 cm of bare cable. We untwist the twisted pairs and connect according to their color, then we immerse the wires into the connectors. We introduce the conductors into the socket housing, each into its own channel.

Important! Make sure the wires touch the copper plates on the connector. While holding the wire, press the wires one by one and fix them together.

How do I connect my home phone?

Despite the fact that mobile phones are very popular today, landline phones also do not lose their relevance. There is a simple explanation for this - a stationary device has a number of unique advantages: it does not run out of battery, and calls to other cities and countries are much cheaper.

In this article, we will show you how to connect your home phone yourself.

How to connect your home phone correctly

In order to connect or, you can contact the specialists or do the connection yourself. To do this, you need to make a minimum of effort - choose the model you like and connect to the network.

Telephone socket and plug

To connect a stationary device it is necessary. The telephone socket is needed in order to transfer the telephone cable wires that go from the PBX to the RJ-11 interface. RJ-11 is a socket of a new type, in old houses there were sockets of the RTShK-4 type. A wired telephone is connected to such an outlet using a plug.

The telephone plug is a box made of plastic. It has two parts - two halves, in one of which four flat contacts are inserted. A telephone cord is attached to them with screws.

The plug and socket have only one function - they are needed for convenient phone connection and ease of use. Communication is carried out by connecting two wires stretched into the apartment, and a cord coming from the telephone.

Connecting to a telephone socket

Let's consider the connection of the device using the example of a modern RJ-11 socket. The home telephone is connected directly to the telephone wall jack via a cable with RJ-11 connectors at the end. One connector is inserted into the telephone jack and the other into the telephone jack. Inside the socket, the wires are wound on screws to which the terminals from the connector are connected.

Phone connection types

It is important to take into account that simple telephones have a two-wire connection type that comes from the PBX. But there are telephones with a four-wire connection type. In this case, to connect the phone, you need the same two wires that represent the two center channels. Most often, these wires can be recognized by their color - these are red and green wires. If you connect your phone without using a telephone jack, these are the wires you need to use. In this case, it does not matter with what polarity these wires are connected: the device will work in any case.

Installing a landline phone

As a rule, you can install a home telephone in any room of an apartment or house. To do this, you just need to run the telephone cable to the desired location. The most convenient option is considered to be kits, which include a landline telephone and an associated radio handset. The advantage of a radio handset is that it can be used to answer calls in any part of the apartment and move around during a conversation.

During the development of communications, several standards have been created for connecting fixed telephones to existing lines. Almost all of them are used to some extent in everyday life and at industrial enterprises.

Within the networks of large organizations that have existed for several decades, one can find simultaneously working models of various designs, mounted at different times. The peculiarities of their device must be taken into account before installing and connecting the telephone set.

Purpose and standards of telephone sockets

The main task of the socket is to provide a quick-detachable and reliable connection of telephone sets to the existing communication lines, created by a stationary part - a socket or "mother-contact" and a movable plug inserted into it: "father-contact".

Design features

Materials and tools

The main accessories that you may need when laying telephone wiring:

side cutters - for cutting the cable;
knife - for stripping the ends of the wires;
screwdriver - fastening the ends to the socket;
screws - fixing the base of the device to the wall;
drill - drilling holes for fixing the outdoor unit;
tungsten carbide drill - typically 4.2 mm in diameter;
plastic inserts in the holes;
"Grinder" with a disc for concrete - to perform hidden wiring;
perforator with a core drill, drill size in accordance with the size of the box;
- to clarify the polarity of the contacts in the connector when connecting;
protective latex gloves - if during the work there is an accidental call to the phone, the potential difference can reach 120V, which is already unsafe with direct contact.

Work order

If you decide to install hidden wiring, you must first make a channel for laying the telephone cable. Using a grinder, grind the channel along the entire length and lay the wire in it, seal the channel with cement mortar.
When making open wiring, you will need special plastic brackets for attaching the cable to the wall and an electric drill with a drill. Insert plastic inserts into the holes with a depth of about 20 mm, and fix the wire under the bracket with a nail or screw. All fasteners are sold in a set, there are no problems with the compatibility of components.
Installation under the skirting board will require the use of a chisel, with which the skirting board is removed from the wall for laying the wire. After that, the plinth is knocked into place with regular nails.
When installing the outdoor box, it must first be connected to the cable. Then fix it on the wall. Here options are possible, determined by the design of the boxes themselves. If its base has holes for fastening, you need to attach it to the installation site and mark the location of the holes on the wall. Using a drill, drill the holes, install the inserts and secure the base of the box with the screws from the kit. Then install the cover, which has special latches for this. The base without mounting holes can be wall-mounted using double-sided tape. The fastening is quite reliable, but when disconnecting the connector, it is advisable to hold the case.
When installing the inner box, you need to use a hammer drill and a core drill on the diameter of the box. After making a blind hole in the wall, install a box in it, connect it to the cable and fix it in the hole. Replace the cover.
When connecting the contacts, use a tester to check the correspondence of the poles (location "+" and "-").

All work is simple and accessible to a non-professional performer.

Types of connectors. Features of the application of RJ11, RJ12 and other types

Telephone connectors are used not only for connecting devices to a communication line. They are used to connect with other devices and communication devices.

Sockets are made with one, two or more connectors and can provide simultaneous connection of several subscribers.

In a wide variety of connectors, it is necessary to consider some of their varieties:

RJ11 - two-wire version, used to connect to line-type networks.
RJ14 - equipped with four conductors and four pins, compatible with most modern phone models. To connect one subscriber, you need to use the 2nd and 3rd contacts. If you need to connect several additional lines, you need to use the 1st and 4th pins. If an overhead telephone socket is used, the line is connected with red and green wires.
RJ25 - has three pairs of contacts, requires the participation of a qualified telephone technician to connect.
RTShK-4 is a legacy of the Soviet period, but it is being produced and used to the present time. Includes a special key. Connection is made in one-piece way with a tap-off box. If there are several points of this type in the room, they are closed using a capacitor.

Let's talk in more detail about devices for connecting RJ11 and RJ12:

The first of these types of products is used for individual connections in conventional telephone networks.
The second is used for networks with heavy loads - in office or public places.

These types of connecting devices have two or four contacts, made like a metal plug, connect to the contacts that are located in the center. For installation, a special tool is desirable - a crossover knife, which allows you to remove the braid without damaging the wire and crimp the plug when installed on the wire.

To connect you need:

remove the braid from the wire to a length of 4 - 5 centimeters;
straighten each core of the cable, the number of which ranges from 4 to 6;
lay all the wiring in the socket grooves;
check for contact between the connector and the telephone cable.

When starting the connection, you need to take care of safety measures when performing work. Be sure to wear rubber gloves that can protect you from electric shock.

General Outlet Standards indicate that a red braid usually indicates a positive conductor, while green indicates a negative rating. The tester will help to verify this.

The connection methods for all sockets are identical, but they differ in the methods of installation depending on the version.

In practice, the installation of popular French-made sockets of the Legrnd type is also carried out. The line of products of this type is very diverse, sockets are available with any type of installation: external, internal and any others. The color coding follows European standards and is identical in similar products from other manufacturers.

When carrying out work on laying a telephone cable, you need to remember the safety rules:
- When chasing a cable groove in brick or concrete, be sure to use safety glasses or face protection to protect your eyes and face.
- Take the same safety precautions when drilling holes for securing the cable or socket base.
- When cutting material from the channeled channels, from the blind hole for the socket box, install a protective disk on the chisel to prevent damage to your hands.
- Work with wiring must be done with protective gloves.
If a polarity tester is not available, use a cut potato. Stick the ends of the wires into the pulp, the surface of the pulp around the positive wire will soon begin to darken.
Modern sockets are made in a safe version. However, they must be installed out of the reach of children.
When stripping the ends of the cable for connection, it is necessary to avoid damage to the insulation of the internal wires and, moreover, the conductors themselves. This leads to a deterioration in the quality of communication and the possibility of a line break.
If an old Soviet two-core wire is used in the form of a plastic ribbon with wires along the edges, it is unacceptable to fasten it by driving nails between the wires. This often leads to line breaks during installation. When the nail comes into contact with the wire, a grounding pair may form, impairing the quality of the connection.

Carrying out all the work thoughtfully and accurately, you can successfully cope with the simple task of wiring and installing sockets. Take it without a doubt and you will be a success!

Despite the rapid decline in the popularity of landline telephones, there are not so many people who are ready to abandon them outright. Admit it, it happens that it is sometimes extremely difficult or even impossible to do without traditional communication.

To connect the device to the switching network, you need a low-current node, the installation of which you can handle with your own hands. We will tell you in detail how to connect a telephone socket without calling the wizard.

There is absolutely nothing complicated in the schemes and methods, and the useful information offered by us, as well as photos and videos, will help to deal with the issue.

The designs of stationary telephones are being modified and improved every year. And modern devices are significantly superior to their predecessors, favorably distinguishing themselves against the background of their high reliability and ease of use.

To ensure the smooth functioning of the device, two conditions are necessary:

Availability of a valid communication line from the automatic telephone exchange.
Possibility of electrical connection of a stationary device to this line.

The only thing that does not change in the field of telephony is the principle of operation of fixed telephones. However, there are significant changes in the designs and connection methods.

Old and new options for telephone switching are presented in the photo collection:

Of the tools for carrying out work, it is necessary to prepare:

building level;
crossover knife;
voltmeter;
screwdriver;
nippers;
lead pencil;
protective gloves;
Double-sided tape;
punch (if mounting a new point).

When choosing a screwdriver, they are guided by the type of surface and the dimensions of the screws used for fastening. To minimize the likelihood of electric shock, it is best to perform all manipulations with a screwdriver with an insulated handle.

Having outlined the installation point of the connection point, using a building level, they correct the horizontal and vertical position of its position

To connect a hidden-type socket, you must first make a hole in the wall for its installation -. This can be done using a perforator equipped with a special crown with a diameter of 60-70 mm.

In the absence of such, work can be done with an ordinary hammer and chisel. But manual labor will take much more time and effort. Then, to the hole made, it is necessary to grind a channel for laying a telephone cable.

There are certain nuances when installing a socket box in.

Stage # 2: Stripping the ends of the veins

Before proceeding with the melting of the wires, it is necessary to strip the ends of the wires, removing the outer layer. Expose the outermost 4 cm of the wires sufficiently.

When stripping a telephone cable, remember that it is very vulnerable to damage. Broken wires will only lead to equipment malfunction. Therefore, it is important to use specialized.

Since it is not always possible to accurately cut the first time, experienced craftsmen recommend making some margin along its length when laying the cable. The extra wire can then be hidden under the cover of the device.

Remove the protective insulation from the ends of the cable with extreme caution, using a cross-cutter, a sharpened blade or side cutters.

The task of the master is to strip the ends of the wires from the braid so that in their bare form they are intact and devoid of any defects.

Stage # 3: Connecting the outlet wires

The stripped wires with the strands apart are connected to the connectors of the box itself, focusing on the designations indicated on the front panel of the indoor unit. With a closed installation method, for the convenience of connecting, the wires are made protruding beyond the wall plane by 50-80 mm.

To observe the polarity when connecting the wires, they are guided by the rule: red insulation on the line with a "-" sign, and green braid with a "+"

If the rule is not followed, taking into account the polarity, there is a great risk that the telephone will malfunction from time to time during operation.

At this stage of work, a voltmeter is required. With its help, you need to check the readiness of the communication line. The line voltage should be between 40-60 volts.

The supplied cable cores are applied to the clamp and tightened tightly with special screws, ensuring a secure fixation. The shape of the grooves to which the conductors are attached facilitates the installation process. It is not necessary to wrap the joints with electrical tape.

When connecting devices, the design of which is equipped with four pins of a fork shape, only the two center pins are activated

Performing open mounting, at the final stage, it remains only to close the housing cover with a latch and secure it with screws. The finished socket is attached to the wall or floor, "planting" it on double-sided tape.

With a closed installation method, making sure that the wires do not intertwine in the socket box, according to the applied markings, the indoor unit is mounted into the wall. After giving the block the desired position, the structure is fixed with spacer screws and self-tapping screws.

At the final stage, it remains only to eliminate the gaps between the socket and the wall, covering it with plaster mortar, and also to close up the channels with the laid telephone cable.

After the gypsum is at the desired strength, the protective bezel is replaced and the bezel is attached. In modern devices, the protective bezel snaps into place on the indoor unit, and the front panel is fixed by screwing in the screws.

There is nothing difficult in connecting a telephone socket. The only thing is that you should not save money by purchasing equipment of a low price range. It does not always comply with the standards and can fail even at the connection stage.

Share your personal experience of connecting a telephone socket, leave comments on the article and ask questions. The contact form is located below.

Telephone is an electrical device that allows people to exchange information at a distance using an electrical signal. The word telephone comes to us from ancient Greece. Tele - translates as "far", and the background - "voice".

After reading the article, any home craftsman can easily connect a landline, fax or several phones in parallel, including a radiotelephone.

What is the voltage in the telephone line

The telephone line is under 40-60 V DC voltage if the telephone is not connected or is connected, but the handset is on the telephone set. During a call, the voltage in the communication line becomes variable with an amplitude of up to 120 V. When you pick up the handset, the voltage drops to 6-12 V. This voltage is not life-threatening, but it can cause unpleasant sensations.

It is impossible to disable the communication line or damage the telephone set when connected. The telephone line may be disconnected for several minutes if the handset is lifted for a long time without dialing a number or if the communication line conductors are short-circuited. The telephone line is automatically disconnected by an automatic telephone exchange (ATS) to save energy. So you can safely start connecting your phone to the communication line on your own.

Before connecting a landline telephone, fax or radiotelephone to the communication line, it is advisable, but not necessary, to check the availability of the communication line. Line voltage can be measured with a voltmeter designed to measure DC voltage.

If the phone is not connected to the line or is connected, and the receiver is on the phone, the device should show a voltage of 40-60 V. If there is no voltmeter, you can check it with a potato, and this is not a joke, but a real way of checking. It is enough to stick the noodle wires stripped from the insulation into the cut of the potato. No batteries are needed as the wires are already energized.

What current will flow
in case of short circuit of telephone line wires

The automatic telephone exchange has a system of protection against failure of equipment and communication lines, which limits the current in case of a short circuit of the telephone line to 40 mA.

For the communication line, one of the free pairs is taken, brown or blue. A twisted pair cable consists of two conductors twisted together. The insulation of one of them is painted in a solid color, and the insulation of the second is white with stripes in the first color.
