How to connect a telephone wire. The cost of connecting a home (landline) telephone from Rostelecom

A telephone socket is essentially a low-current type of socket device, the main functions of which are:

1. Connecting wired and wireless devices to the appropriate network and provision of telephone communication.
2. Implementation connection of modems and faxes.
3. Connection and organization of mini-PBX operation.

In practice, connecting a telephone socket is much easier than connecting an electrical one. However, this process still requires care and precision, since it requires a number of electrical installations involving high voltage.

Installation and connection of such devices is ideal for people with little experience in this field, or beginners who are just gaining relevant experience.

Previously, this process raised fewer questions, since there was a single standard regulating the installation of such devices. Today, there are several European standards called Registered Jack (RJ). There are several in various ways connecting telephone sockets, this process can be carried out independently with RJ-14 and RJ-25 devices.

Features and connection diagram

RJ-11 socket

Telephone sockets have their own individual connection features; if we talk about the modern and most common standards RJ-11 and RJ-12, they have the following connection nuances:

1. Into the device design may include 2-4 contacts, which are small metal plugs. Between these elements, the cores of the supply wire must be buried.
2. Connecting the phones themselves occurs exclusively through 2 central contacts.
3. For installation of devices With the specified standard, professional craftsmen use a special type of working tool called a cross-cutting knife. However, if you do not plan to use it frequently in the future, then you can limit yourself to a very ordinary knife with a sharpened blade. Such a tool is used to deepen the cores; when cutting through the insulating layer, contact will be ensured.
4. Before straightening lived it is necessary to remove the outer layers from the wire; 4 cm is enough to carry out such stripping.
5. For internal laying It is recommended to use a KSPV cable, which has a single wire core in its design, which is most often made of copper. The outer shell is usually made of white colored plastic. TRP cable is most often used as a distributor.

Required tools and materials

Depending on the type of telephone jack, as well as the standard used, different tools and materials may be required.

1. Screwdriver, which in terms of the type of working surface and dimensions corresponds to the screws used to fasten the device. The screwdriver handle must be insulated to avoid.
2. Cable, if the old device is not replaced, but a completely new one is installed.
3. Hammer, as well as the cable, will be needed if a new outlet is being installed.
4. The outlet itself.
5. Knife with a sharp blade.
6. Self-tapping screws.
7. Wire cutters.
8. Insulating tape.
9. Universal or tester.
10. Protective gloves.
11. Single-sided and double-sided adhesive tape.
12. Graphite pencil and a marker with bright paint, which will be needed for markings.

Step by step instructions

Initially, we will consider a simple way to connect a universal telephone socket. Today, the most common devices are those that comply with European standards RJ-11 and RJ-12.

In order to connect them, you must adhere to the following algorithm of actions:

1. Initially, you will need to turn off the power supply and wear protective gloves, since the voltage in the telephone network is 60V, and in operating condition it can reach 110-120V.
2. Using side cutters remove the insulating layer from the conductors, while it is important not to touch the conductors themselves. The length of the stripped cable should be about 4 cm.
3. Using a tester determine the polarity of the contacts.
4. Connect the conductors to the contacts. In a telephone socket, the red wire has negative polarity, and the green wire has positive polarity. It is not necessary to follow the connection rules taking into account polarity, but there is a certain risk that in the future the telephone set will from time to time make its own during operation.
5. Connect the cable cores, then tighten and ensure reliable fixation using special screws for clamping.
6. Some models They have 2-4 contacts in their design, which have a fork shape; these elements are made of steel. In such a situation, 2 central contacts are used.
7. Commit and mounting a telephone socket on the wall surface. This can be done using double-sided tape, but most in an efficient way is the use of self-tapping screws.
8. Snap the lid of this device.

There are varieties of hidden telephone sockets. The connection process for them is no fundamentally different from connecting classic device options.

Significant differences exist only in the installation process and are as follows:

1. Apply markings to the wall surface future location of the telephone socket.
2. Previously, you will need to make a hole in the surface using a hammer drill; it will be needed for the subsequent installation of the socket box. Fixation and fastening of this element is achieved through the use of self-tapping screws.
3. Device fastening inside the mounting box can be done using special-purpose spacer screws.
4. Put on the outer protective casing, after which the voltage can be returned to the network and the installed device can be tested.

At the same time, you need to know that absolutely any type of telephone sockets can be not the usual single, but a double device. Such devices are usually installed in offices or other premises where there are several telephone sets with different numbers, but sometimes it may be necessary to install them at home.

The installation or connection process is not fundamentally different from the work carried out with a single structure. The only change is an increase in the number of conductors requiring connection.

Types of telephone sockets

When considering different types of such devices, one of the main classifications is their division according to the installation method:

1. Devices for external installation.
2. Devices with internal wiring.

A secondary classification, applicable to both types, is the division of these devices according to the number of available connectors:

1. Single connector models designed to connect 1 device, they are the most popular option for installation in private houses or residential apartments.
2. Multi-connector models They allow you to connect several different devices at once; they are most often found in offices and office premises.

Also, on the modern market there are sockets with different connectors.

This parameter is determined by the type of standard used:

1. RJ-11 is one of the most common options, it implies the presence of 2 conductors in the design. Such devices are most often found and are recommended for installation if there is a line-type telephone line to which the device is connected.
2. RJ-12 less common because they are rarely used for domestic purposes. The main purpose is to connect to office mini-PBXs or a number of types of network cards.
3. RJ-14 It has 4 conductors and the same number of contacts. It is a universal connector designed and suitable for most modern models of telephone equipment. To connect and ensure the operation of one line, contacts 2 and 3 are used; if for some reason several lines are required, then the connection occurs through contacts 1 and 4. Surface-mounted sockets must use a green and red conductor, which are usually located in the center of the fixture.
4. RJ-25 includes 3 pairs of working contacts in its design. Devices of this type are extremely complex and unsuitable for installation on your own. To carry out this process, you will need to hire a qualified specialist who understands electrical and telephony issues.
5. RJ-9 is a special type of connector, the main task of which is to connect the handset directly to the device.
6. RTShK 4 is already a technically outdated type of sockets that were common in the USSR in the past; the design includes 4 wide contacts and a key. Designed for a specific connection option in a permanent way; for its implementation, the presence of a branch-type box is required. The presence of several telephone sockets within one room contributes to the creation of a special electrical circuit, an additional capacitor is required to close it.

Regardless of the type of telephone socket, you will need to install a special type of power cable inside this device. The different options have no design differences; all plugs have similar dimensions and connectors, but they may differ in the number of contacts available.

telephone wire marking

All the main issues relating to the installation and connection of telephone sockets have been considered, summing up the following useful recommendations:

1. Most Popular Today, it is a built-in type of device, since it fits harmoniously into any room and is an extremely inconspicuous element. However, it must be taken into account that its installation will take longer and the wall decoration will suffer.
2. Best purchase devices that were produced by well-known and trusted manufacturers who have managed to positively establish themselves in this field. Today, such companies are Legrand and Vico.
3. On some models There may be no numbering of contacts, usually applied to the body of the device. In this case, knowing the rules of color marking can help: green, orange or blue in combination with white are used to indicate positive contacts; the same colors, only monotonous and without the addition of white, indicate negative contact.
4. If a telephone socket is installed old style, then it also doesn’t hurt to know the color marking rules that were used before: orange, black or green conductor is positive; the red, yellow or blue conductor must be negative.

Sockets are designed for connecting electrical appliances of different power in any room; there are also low-power ones for turning on specific devices, in particular, these include telephones. What connection is needed and how many wires are there - details below.

Features of a telephone socket

Despite the development cellular communication, many people continue to use wired telephone communication for various reasons. In order to connect a landline telephone, it is necessary not only to lay a cable from the telephone exchange to the house, but also to install an outlet to which the device is directly connected.

Peculiarities:

1. Traditionally, the body of a telephone socket is made of plastic, and in rare cases, ceramic.
2. The body of the telephone socket contains terminals to which the wire running from the telephone cable in the apartment is connected.
3. The phone plug is securely fixed thanks to spring-loaded contacts.

There are also more modern schemes for connecting landline phones, which use not only outdated 4-channel, but also more modern four-wire connectors for connection. To connect in an apartment or small office, you can use 1 telephone and, as a result, 1 two-wire wire.

If it is necessary to install several telephones per number, then in this case a 4- or 6-wire cable is inserted into the room from the switchboard.

A telephone socket can be installed almost anywhere in the room, as long as it is convenient to connect a telephone to it. Telephone socket should be installed so that you can connect a telephone to it without any problems. The telephone socket can be installed on the floor, wall, and even in the electrical panel on the driveway. The telephone socket must be protected from moisture, dust, as well as damage and provide reliable connection telephone set with telephone line.

A telephone socket can be connected without any problems, but you must first determine what type of socket you will need for the connection. Sockets can be built-in (Euro socket) or external, installed on any surface, most often on walls.

In addition to installing the outlet, certain conditions must be met:

1. The cable introduced into the room should be stripped of insulation at a distance of approximately 3 cm.
2. The bare wires are inserted into a telephone socket (old style) and connected to 2 terminals.
3. After that, the socket cover is closed and the phone plug is inserted into the socket.

If the phone does not work, you can try switching the cable to another pair of contacts. If you are installing a hidden type telephone socket that is mounted into the wall, to install it you will need to make a recess, as well as a hole for laying the cable.

First, a wire is connected to a socket of this type, after which the box is installed to the wall using dowels and screws or expansion screws.

After this, the contacts of the socket are checked using a multimeter and, if everything is in order, then a decorative overlay is fixed on top. If a person is not well versed in installing not only electrical, but also telephone wiring, especially when connecting several telephones, you should invite a specialist who will correctly connect all the devices.

Rules for connecting an outlet

A socket is a device that serves to connect all equipment to the electrical network. The socket consists of 2 main parts - an outer plastic casing and a working part, which is installed on an insulating base and includes spring-loaded contacts, terminals for connecting wires, as well as fasteners that allow it to be securely fixed.

Wiring an outlet involves several main steps:

1. First you need to turn off the voltage, this is done by turning off the circuit breakers on the panel.
2. If this is not possible for various reasons, then you should wear rubber gloves.
3. The electrical wires should be routed through the hole in the socket box (if there is none, then you need to drill it).
4. Afterwards, the socket box should be installed; it is fixed in the wall using plaster.
5. The ends of the wires are stripped at a distance of approximately 1–1.5 cm, after which they remain connected to the terminals and securely fixed.

The working part of the socket is put in place and, depending on the design, it is fixed with screws or special mounting tabs. Afterwards, all that remains is to install the decorative frame and secure it with a screw.

If the outlet is grounded, then you should be careful not to mix up the wires.

Typically, the ground wire has a sheath color of yellow-green, yellow, or green. The ground wire is connected in the same way as conventional wires - by inserting it into the terminal. Installation of two sockets located next to each other is carried out as follows - the part of the cable used for wiring is cut to the required length. First, the first socket is installed, the power supply and wires from the cable are fixed in the terminal blocks. The cut cable is laid through a cable channel or groove to the second socket, and its ends are also fixed in place. Afterwards, all that remains is to fix the sockets and install the decorative trim.

The nuances of connecting a telephone socket

Connecting a telephone socket is usually not difficult; the main thing is to first understand their types, since now there are several of them, for example, the rj11 model, which is widely used for home phone. This socket has only 2 contacts. In order for the phone to work, you must correctly connect the contacts to the telephone cable (pinout).

If the telephone is installed after all repair work has been carried out, then in this case the telephone socket is installed directly on the wall:

• 2 holes are made in the wall;
• Dowels are inserted;
• The socket is screwed to the wall;
• The wire to it is tucked into the cable channel, after which it is connected to the contacts using screws.

If you need to install an additional one to connect a second telephone set, then you should connect 2 sockets with a wire, one, for example, in one room, the second in another. The main thing when connecting wires is to observe the polarity so that the two sockets work correctly.

If there is no opportunity or desire to install a new line and a second socket, you can purchase a radiotelephone with 2 handsets so that you can talk from different rooms.

It is best to carry out all work with rubber gloves, although the voltage in the telephone network is low, but in the event of a call, the voltage can reach 120 volts, although of course this is not fatal, but unpleasant sensations are guaranteed.

Instructions: how to connect your home phone

If telephone line cables are installed in the house, then connecting a home telephone will not be difficult. To do this, you need to come to the company’s office, where you write an application to connect the phone. In addition to the connection, if universal fiber optic communication lines are installed in the house, you can connect the Internet and interactive television along with the telephone.

Options:

1. Connecting landline phones is done by connecting a plug and socket, and modern models are now used.
2. The old type RShTK-4 is practically not used anywhere now.
3. There are universal models of sockets and plugs that allow you to connect different standards.

The laying of the telephone wire from the panel to the apartment or other premises is usually carried out by signalmen, and then, depending on preferences, the telephone is installed anywhere in the premises.

But, it should be borne in mind that if the phone is multifunctional, then it will need power supply, and it is advisable to install it near an electrical outlet.

If after connecting the phone it does not work, you should check all the wires, sometimes the wiring in the socket may be to blame, it is worth re-soldering them to other contacts, and everything should work. Usually the phone connection diagram is shown in the instructions, but sometimes it happens that it is missing. In this case, you have to seek the help of a specialist.

To connect a landline telephone to a line, you need a working line from the PBX and the ability to connect a telephone to it. Telephones are connected to the line using telephone sockets.

There are several standards for such sockets; they are used for different purposes: connecting one or more telephones, creating leased lines. In apartments, the RJ 11 standard socket is most often used. How to connect a telephone socket of this standard yourself?

Types of equipment

With the development of technology, telephone sets are improved, but in general the principle of their operation remains unchanged. To connect them to the communication line, special sockets are still used.

In Russia, from the 80s until recently, a single standard was used - RTShK-4. Even earlier, wires were connected by simply twisting them together. Now there are several standards.

The development of microprocessor technologies has led to the replacement of RTShK-4 type sockets with others - marked RJ. With their help, you can connect up to four telephones to the line. The abbreviation RJ stands for Registered Jack. There are several standards for telephone sockets with this designation:

• RJ 9 - connector that connects the handset to a landline telephone,
• RJ 11 - it is the one most often used in residential buildings and apartments, the first standard adopted in the USA, also called the “Euro socket”, has two contacts and connects one telephone,
• RJ 14 - often used in office premises, has contacts and 4 wires, is convenient for connecting additional lines - you can connect two telephones with a separate line, in apartments it is rarely used to connect a telephone,
• RJ 25 is a model with three pairs of contacts; it is difficult to connect it yourself; it is better to entrust such work to specialists.
• RJ 45 is a device with 4 pairs of contacts; it is used to connect computer and telephone networks or connect a telephone to a line.

There are also combined versions of RTShK-4 and RJ 11 with both types of connectors. Such devices are used to connect computer and telephone networks. In addition, they can be used to connect devices with old and new plugs to the network.

There are also RJ 12 sockets, but they are not standard, as Legrand products are designated as RJ11 or RJ 25. TAE type devices are used to connect German and French telephone sets to the line.

Installation methods

Telephone sockets can be installed in an open or closed manner. The open method means that all the decoration on the wall is preserved; the equipment is attached directly to the wallpaper or paint.

In this case, the wires are hidden in a cable channel located in the baseboard or on the wall. You can find cable channels of different colors and sizes, baseboards with a cable channel inside. Models with snap-on lids are convenient. There are also baseboards with built-in sockets. When buying them, choose those whose front panel fits well to the base, otherwise over time it will begin to lag.

Sometimes devices are mounted not on the wall, but on the floor. When connected open method they can even be glued with double-sided tape.

If the telephone socket is connected in a closed (hidden) way, the wires are laid in the channel before the socket is installed in the socket box. Sometimes the wires are laid in the wall and the socket is installed outside. Most often they use a copper single-core cable KPSV in a white polyethylene sheath or a copper single-pair cable TRP.

Most often, telephone sockets are not mounted separately, but as part of an outlet block, for example, together with an electrical outlet and a switch, as in the photo.

Advice! To disguise the structure, place them behind furniture facades or behind monitors and televisions.

Telephone socket device

A telephone socket consists of several main elements:

• housings made of dielectric (non-conducting) material - ceramics or plastic,
• contacts - spring-loaded brass parts that are needed for reliable connection of conductive parts and uninterrupted flow of current,
• terminals - adapters for connecting cables.

The contact sockets of the device are recessed into the housing. This arrangement prevents accidental short circuits.

Telephone sockets can be single or multi-socket. Single-connector models allow you to connect one telephone set, multi-connector models allow you to connect several. The RJ 11 socket is a single-socket socket; it can be used to connect only one telephone.

RJ 11 connection

RJ 11 has two wires, so it’s easy to connect it yourself at home. To do this, you will need to connect the two ends of the wire with certain contacts in the socket, so that in the plug and in the socket they are located in mirror image. For installation you need:

• two-core cables with a thickness of 0.3-0.5 mm,
• screwdrivers - flat or Phillips, depending on the type of screws, with an insulated handle,
• drill,
• insulation removal tool,
• tester,
• tool for crimping contacts - you can not use it, but crimp the contact plates with a screwdriver, but then the plug will not look so neat.

The video shows how to properly connect a telephone socket to the line.

Important! Work on connecting the socket should be carried out using rubber or latex gloves. Voltage in low current network reaches 60 V, decreasing to 12 V when the handset is removed. If they try to call the phone, a voltage of 120 V will arise in the wires, that is, they may receive an electric shock. With such tension it is not dangerous, but unpleasant.

First of all, you need to turn off the electricity. Next, you need to remove the insulation from the wires. This is done with side cutters, pliers or a regular knife. You need to carefully remove the insulation from the wires so as not to damage the core of the telephone cable itself, otherwise it may break in the future.

Do not burn the insulation and then remove it with your fingers. You can burn yourself with hot plastic; in addition, with this method it is difficult to remove the insulation carefully. You need to strip the wires at a distance of 4 cm from the end.

It is advisable to strip the wires generously: they are thin and fragile and can be easily damaged. The excess part, if any remains, can be easily hidden under the socket body. For closed installation, for convenience, the wires are made to protrude beyond the wall surface by 5-8 cm.

Next, use a tester to check the polarity of the wires. Typically, in telephone jacks, the red wire is positive and the green wire is negative. But it is better to check the polarity, since it is not known how the wires were located before. If it is not possible to use a tester, then connect the cables according to the diagram that comes with the device.

To check if the line is working, you need a voltmeter (multimeter). The line voltage should be 40-60 V.

After this, the wires are connected to the outlet according to the diagram. To do this, you will need a screwdriver - insert the wires into the connectors and tighten the screws, clamping them well.

If you need to install the outlet in a closed way, then first markings are applied to the wall showing where the device will be located. Then, using a puncher, holes are made according to the markings and the structure is secured with self-tapping screws. A protective casing is installed on top. At the end the device is also tested.

If you are installing a new point and there is no space for sockets on the wall, then first make a recess for them - a socket box. It is drilled out using a special crown attachment on a hammer drill with a diameter of 6-7 cm. Channels for laying wires are also drilled using a hammer drill. If there is no hammer drill, this can be done with a hammer and chisel. But such work is much longer and more labor-intensive.

After this, install the device in the socket box, making sure that the cables are not intertwined. Then the socket is secured using self-tapping screws and expansion screws. The gaps between the socket box and the wall are covered with gypsum mortar.

When the solution hardens, install the protective edging and front panel. The protective edging in modern models is attached with latches, and the front panel is fixed with screws.

Connection diagrams

Telephone sockets will be connected according to certain patterns. Their wires are marked with color or numbers; there are different options, but a wiring diagram for the telephone socket is usually included with the device.

Polarity is usually not that important, but some devices may not function properly if it is not observed. The connection diagram is shown in the figure.

Twisted pair cores are also marked according to different standards, which are given in the tables. There is an old, new and German scheme.

To properly connect your phone and get a well-functioning line, you need to take into account some recommendations.

1. Most often, an internal (hidden) outlet is installed. It fits well into any interior, but it is more difficult to install, and it can also damage the decorative finish of the walls. Open type sockets are easy to maintain, install and dismantle; their installation does not damage the finish, but they do not look very aesthetically pleasing.
2. Preference should be given to products from well-known manufacturers. These include the companies Legrand and Vico.
3. If the socket does not come with a wire marking diagram, you can use the tables above. In the new marking, the positive wire of the RJ 11 socket is the same color as the negative wire, but with the addition of white. According to the old scheme, positive is green and negative is red. In the German version, negative is white, and positive is brown.

Installation of other types of devices

The RJ 11 socket can be replaced with an RJ 25 model. This is not advisable, but if you accidentally bought the 6-pin version, then use only 3 and 4 to connect. They are labeled the same as the two pins of the RJ 11 model.

A universal socket (RTShK-4 + RJ-11) is suitable for telephone sets of the old standard. You can also use an adapter from the old standard to the new one.

Conclusion

Using the diagrams and recommendations given in the article, you can independently install a telephone socket of the new standard and connect a telephone to the line. Connecting a device with two contacts is not difficult; the main thing is to choose models from well-known manufacturers when purchasing, and when connecting a socket, carry out the work carefully and observe polarity.

Installation of information switching on one side may seem simpler than electrical lines. After all, they do not contain a life-threatening voltage of 220/50. But installing and connecting a telephone socket is not as simple as it seems at first glance. This is due to the great variety stationary devices, which are used in everyday life, as well as connectors, with the help of which the connection is made. Next, we will tell you how to connect a phone socket with your own hands, providing all the necessary diagrams and photo examples.

Types of connectors

Below are the types of new connectors:

Step-by-step installation instructions

So, how to install and connect a phone socket? First of all, you need to check the availability of the device connection diagram. The tools you will need are a screwdriver, an electric drill and the telephone socket itself.

Note: in operating condition, the voltage on the line can rise to 120V. Therefore, in order to limit yourself from such unpleasant moments when installing and connecting a telephone socket to the network, it is better to use.

Before proceeding with installation, it is necessary to disconnect the electrical network. Then, using side cutters or a knife, remove the insulation from the conductors. This must be done carefully so as not to damage the wires. After all, if they are damaged, they will break easily. You need to strip the cable along a length of 4 cm. Read about that in our article.

Use a tester to determine the polarity of the conductors. Typically, a telephone jack has a red positive conductor and a green negative conductor. But it is better to check, since it is not known how the installation and connection were carried out. If the device is not at hand, the connection is made according to the existing plan (the diagram is attached to the device).

The next step after checking the polarity is to connect the cable cores, as shown in the photo below. After this, a telephone socket is fixed on the wall. After installation, you need to connect to the network and test the installed device.

It should be noted that the housing can also be of a hidden type. How to install and connect a hidden phone socket? First of all, it is necessary to mark the wall where the device will be installed. Using a hammer drill, make a hole and secure the structural elements with self-tapping screws. The installation ends with fastening the protective housing and testing the device that has been installed.

If at home you need to install and connect a telephone socket with 2 outputs (installation of several devices with different telephone numbers), then one nuance should be taken into account - installation occurs with a large number of conductors. But overall there are no significant differences in the work.

Connection diagrams

The method of determining polarity without a device has a number of advantages. It has been tested more than once. There are many options and when installing and connecting the device, there is a possibility of even more confusion.

The telephone socket is installed according to certain patterns. Such a scheme is developed in advance. As a rule, polarity does not matter much. But some telecommunications devices may fail or function incorrectly if this is not taken into account. The device connection diagram is provided below:

In order to simplify installation, manufacturers mark the contacts (the diagram and designation must be included with the device). It can be in the form of numbers that are written near the contacts or on the diagram. Or the wires are designated by a certain color.

How twisted pair cable cores are correctly marked when installing and connecting a socket is indicated in the tables below:

Well, the last thing I would like to provide you with is useful tips how to connect a telephone socket with your own hands. So, consider the following nuances during installation:

• Today, the most popular is the internal telephone socket. Since it can harmoniously fit into any interior of the room and is not very noticeable. But when installing it, it is necessary to take into account the fact that the wall decoration may be damaged. And it will take more time.
• You should buy products from trusted manufacturers. These include the companies Legrand and Vico. After all, they have already proven themselves positively in the modern market.
• If the contact numbering was not indicated on the body of the purchased device, then you need to familiarize yourself with the rules for marking wires by color. So, to indicate positive contacts, green, blue and orange are used together with white. For negative contacts, use the same colors, only without white.
• The old format telephone socket has a different marking standard. Therefore, if you are installing just such a device, then you need to know these rules. For example, the colors used for plus are black, orange and green. For minus - yellow, blue and red.

So we looked at the technology for installing and connecting a telephone socket to the line. We hope the information provided helped you complete the installation yourself!
