The telephone socket is inherently a low-current type of socket-outlet devices, the main functions of which are:
- Connecting wired and wireless devices to the appropriate network and telephone connection.
- Implementation connections of modems and faxes.
- Connection and organization of the mini-automatic telephone exchange.
It is much easier to connect a telephone socket in practice than an electrical version. However, this process still requires caution and accuracy, since for its implementation it is necessary to perform a number of electrical work associated with high voltage.
Installation and connection of such devices is ideal for people with little experience in this area, or beginners who are just gaining relevant experience.
Previously, this process raised fewer questions, since there was a single standard governing the installation of such devices. Today, there are several European standards called Registered Jack (RJ). There are several different ways connecting telephone sockets, this process can be independently carried out 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 RJ-11 and RJ-12 standards, they have the following connection nuances:
- Into device design 2-4 contacts can enter, which are small metal plugs. Between these elements, the cores of the supply wire must be buried.
- Connecting the phones themselves occurs exclusively through 2 central contacts.
- For mounting accessories with the specified standard, professional craftsmen use a special type of working tool called a crossover knife. However, if in the future its frequent operation is not planned, then you can limit yourself to the most ordinary knife with a sharpened blade. Such a tool is used to deepen the cores; when cutting the insulating layer, contact will be ensured.
- Before straightening lived it is necessary to remove the outer layers from the wire, 4 cm is enough to carry out such a stripping.
- For internal lining it is recommended to use the KSPV cable, which has a single-wire core in its construction, which is most often made of copper. The outer casing is usually made of white plastic compounds. The TRP cable is most often used as a distributor.

Required tools and materials
Different tools and materials may be required depending on the type of telephone jack and the standard used.
- 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.
- Cable, if the old device is not replaced, but a completely new one is installed.
- Puncher, as well as the cable, will be needed if a new outlet is being installed.
- The outlet itself.
- A knife with a sharp blade.
- Self-tapping screws.
- Nippers.
- Insulating tape.
- Universal or a tester.
- Protective gloves.
- Single-sided and double-sided adhesive tape.
- Graphite pencil and a marker with bright paint, which will be required for marking.
Step-by-step instruction
Initially, a simple way of connecting a universal telephone socket will be discussed. Today, the most common devices are those that comply with the European RJ-11 and RJ-12 standards.
In order to connect them, you must adhere to the following algorithm of actions:
- Originally, you will need to disconnect the power supply and wear protective gloves, since the voltage indicator in the telephone network is 60V, and in working condition it can reach 110-120V.
- Using side cutters remove the insulating layer from the conductors, while it is important not to touch the cores themselves. The stripped cable should be about 4 cm long.
- Using a tester determine the polarity of the contacts.
- Connect the conductors to the contacts. In a telephone jack, the red wire is negative and the green wire is positive. It is not necessary to follow the connection rules, taking into account the polarity, but there is a certain risk that in the future the telephone set will give its own from time to time during operation.
- Connect the cable cores, then tighten and ensure reliable fixation using special screws for pressing.
- Some models have in their design 2-4 contacts, which have a fork shape, these elements are made of steel. In such a situation, 2 central contacts are used.
- Carry out commit and fastening the telephone socket to the wall surface. This can be done with double-sided tape, but the most effective way is to use self-tapping screws.
- Snap the cover of this device.
There are varieties of hidden telephone sockets. The connection process for them does not fundamentally differ from the connection of classic versions of devices.
There are significant differences only in the process of their installation and are as follows:
- Apply markings on the wall surface the future location of the telephone socket.
- Pre, you will need to make a hole in the surface with a punch, it will be needed for the subsequent installation of the socket. Fixation and fastening of this element is achieved through the use of self-tapping screws.
- Fixing the device inside the back box can be done using special-purpose spacer screws.
- Put on the outer protective case, 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 kind of telephone sockets may not be the usual single, but double devices. Such devices are usually installed in offices or other premises where there are several telephones with different numbers, but sometimes it may be necessary to install them at home.
The installation or connection process does not fundamentally differ from work carried out with a single design. The only change is the increase in the number of wires that need to be connected.
Types of telephone sockets
When considering different types of such devices, one of the main classifications is their division according to the method of installation:
- Devices for external installation.
- Deviceswith internal wiring.
A secondary classification applicable to both types is the division of these devices according to the number of available connectors:
- Single-socket models designed to connect 1 device, are the most demanded option for installation in private houses or residential apartments.
- Multi-connector models allow you to connect several different devices at once, 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:
- RJ-11 is one of the most common options, it implies the presence of 2 conductors in the structure. Such devices are most often found and are recommended for installation if there is a line-type telephone trunk to which the device is connected.
- RJ-12 less common, since they are rarely used for domestic purposes. The main purpose is to connect to office mini-automatic telephone exchanges or a number of types of network cards.
- RJ-14 has 4 conductors and the same number of contacts in its design. 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 is made through contacts 1 and 4. In plug-in sockets, you must use a green and red conductor, which are usually located in the center of the fixture.
- RJ-25 includes 3 pairs of working contacts in its design at once. Devices of this type are extremely complex and unsuitable for self-assembly. To carry out this process will require the involvement of a qualified specialist who understands electrical and telephony issues.
- RJ-9 is a special kind of connectors, the main task of which is to connect the handset directly to the device.
- RTShK 4 is already a technically outdated type of sockets, which were widespread in the USSR in the past; the design includes 4 wide contacts and a key. Designed for a specific connection option in a one-piece 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. Different versions have no structural 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 related to the installation and connection of telephone sockets have been considered, summing up, you can give a number of the following useful recommendations:
- Most popular today, it is a built-in type of device, since it harmoniously fits into any room and is an extremely invisible element. However, it must be borne in mind that its installation will take more time and the wall decoration will suffer.
- The best thing purchase devices that were produced by well-known and proven manufacturers who have managed to positively recommend themselves in this area. Today, such companies are Legrand and Vico.
- On some models the numbering of contacts, usually applied to the body of the device, may be missing. In this case, knowledge of the color coding rules can help: green, orange or blue in combination with white are used to indicate positive contacts; the same colors, only monotonous and without added white, indicate negative contact.
- If you are installing a telephone socket old model, it does not hurt to also know the color coding rules that were used before: orange, black or green conductor is positive; red, yellow or blue conductor must be negative.
Telephone socket - a device by which the telephone is connected to a line or its separate direction. The device allows you to disconnect the device and quickly connect it to the network in another room. There are different types, each of which has its own characteristics, and not only external, but also in terms of installation.
Structure and classification system
Any socket for a telephone consists of the following parts:
- Housing. Made from dielectric materials, usually plastic or ceramic.
- Spring loaded contacts. Metal is used for their manufacture. The contacts allow electrical current through the telephone wires and plug to pass into the telephone.
- Clamps. Used to connect the wire to the network.
Telephone sockets are connected in two ways - overhead (wall, open) and hidden. In the first case, the wiring is located on the surface, and the socket is installed directly on the wall. In the second way, the socket is mounted in a special socket box, which, together with the wires, is hidden in the wall under the plaster.
Basic standards
With the development of technology, outdated sockets are being replaced by new ones. More and more consumers are changing the RTShK-4 to a modern RJ-11 socket, the latter is considered universal. Its connector is the same as in other species, the difference lies in the number of wires running in the cable.
There are 5 standards for telephone sockets:
- RTShK-4. Now it is practically not used. Consists of a body and 4 contacts. The fork has 4 plates made of metal. There is a plastic pin in the center, which provides rigidity to the connection.
- RJ-11 and RJ-12. These connectors are the most common. Used to connect different types of phones. They can have 2, 4, 6 contacts. Suitable for home use.
- RJ-14. The sockets are intended for installation in offices where you need to connect a telephone-fax machine, modems for the Internet and similar devices. Sometimes the design has 4 pins connected to four-wire wires. This makes it possible to use two different lines at the same time.
- RJ-25. Similar to the previous species, it is found in office buildings. 6 connectors are used to connect local area networks, modems, faxes and other necessary equipment.
- The last standard is called combined. By design, the socket is a combination of RTShK-4 and RJ-11.
Note! There is another standard not included in the list - RJ-45. Used to connect complex circuits in laptops, modems, etc.
Schemes and connection methods
The features of connecting telephone cables vary depending on the type of sockets. For example, the installation and connection of the most common of them - RJ-11 and RJ-12 - have several nuances:
- In the design of the socket, there are 2 and 4 contacts, which are small in size. In the center, there must be a deepening for the cores of the supply cable.
- Phones are connected to two center contacts.
- To deepen the veins, you need a cross cutter. If it is not there, you should use the usual one.
- Before straightening the wires, you must strip the wire about 4 cm.
- During concealed installation, experts advise using a KSPV cable with a copper core. The TRP cable is not suitable in this case - it is better to use it as a distributor.
Preparatory work
Before installing or replacing the telephone socket, you must prepare tools and materials:
- screwdriver with a handle covered with insulating material;
- socket box;
- cable - useful in case you need to install a new outlet, and not just replace the old one;
- puncher;
- directly the outlet;
- several self-tapping screws;
- nippers;
- insulating tape;
- multimeter;
- gloves for hand protection;
- double-sided tape;
- pencil and bright marker.
The set of tools may vary depending on the installation method.
Step-by-step instruction
An open installation action plan looks something like this:
- Protect your hands by wearing rubber gloves. This is important: the voltage in the network sometimes reaches 110 - 120V.
- Using a side cutter, remove the insulating layer from the wire by about 4 cm. Care must be taken not to damage the conductors.
- Using a multimeter, determine the polarity of the contacts. Although it is believed that following the rules of polarity is not necessary.
- Connect the contacts to the conductors.
- Connect the cable cores. Secure with special screws.
- In designs with 4 contacts, use the center 2 when connecting.
- Secure the outlet to the wall using tape. For greater reliability of fastening, it is better to take self-tapping screws.
- Put on the cover.
Connecting a hidden socket has no fundamental differences. But it has some peculiarities:
- Immediately mark the wiring and the location of the outlet on the wall.
- Using a puncher, make a hole for the socket. You will need self-tapping screws to secure it.
- The structure is fixed in the socket with spacer screws.
- After finishing the installation, connect the electricity. If done correctly, the outlet will work.
Devices are available as double or single. Dual phones are usually installed in offices - provided that there is a need to use two phones at the same time. They are connected in the same way.
Following simple advice from experts will help prevent mistakes in installation:
- Better to use flush-mounted devices. They fit into the interior more harmoniously than the others. But to install them, you will have to break the integrity of the walls and wall covering.
- In the selection process, it is recommended to pay attention to only proven firms with a good reputation. This is a guarantee of safety and reliability.
- Most outlets are numbered. If there is no marking, you should look at the colors. Green, orange or blue contacts in combination with white are positive, contacts of the same color, but without white, are negative.
- During the installation of products of the old standard, it will not be superfluous to remember the color design of the contacts: orange, black and green - positive, red, yellow, blue - negative.
The types of sockets for connecting a telephone differ in design, installation method and other parameters. If you follow the instructions, it will be easy to install these devices.
In fact, we are mostly familiar with the mechanism for connecting a telephone jack. In fact, there is nothing difficult here. If you have basic training or even theoretical knowledge, then you can manage it in half an hour, taking into account the laying of wires.
Types of telephone sockets
Are you going to connect your phone? To answer the question of how to do this, you first need to decide on the type of outlet. A few years ago this question would not have been asked, since there was only one type - RTShK-4. In every house where there was a telephone, just such standard devices were installed. Today, Soviet-era standards have been replaced by European ones - RJ11 and RJ12.
RJ11 is used in apartments and houses. It is equipped with only two wires.
RJ12 connects to four wires. It is used as a wiring for office PBXs with multiple channels. If you are planning to install the phone at home, then it is better to focus on RJ11.
Methods of mounting a telephone socket
If you have minimal knowledge, you can connect the telephone network yourself in 5-10 minutes. There are two installation methods - open and closed. The open method implies installation on the surface without removing the finishing layer.
For example, if you have already completely made repairs and now you need to hold the phone, then the outlet is installed directly on the wallpaper or paint. At the same time, the cable - the channel is hidden under the plinth. The open method of fastening can be carried out, in general, without mounting on the wall - the socket can be located on the floor.
It contains 4 screws. The two closest to the connector do not need to be touched. The wire is secured in the two remaining screws. Next, insulation is laid - the conductors are connected to the clamp and pressed with screws. After that, the housing cover is closed. The work is ready.
It is important to know! All work on open mounting should be carried out with gloves. Better to use latex. There were cases of stress when they tried to call the phone. At this point, you can get an electric shock. The blow will, of course, not be fatal, but sensitive.
The hidden installation method involves laying the telephone wire before the socket is connected. In this case, its location is planned.
Sometimes the wires are hidden in the wall, and the outlet is taken out. Visually, this mounting method resembles standard electrical outlets. Concealed and open mounting methods are called external and internal. In general, there are no fundamental differences between them.
Connecting a telephone socket RJ11
Before proceeding with the installation, you should prepare a basic set of tools and materials:
Modern phone jacks are available in different sizes and colors. To connect RJ11 yourself, you need to adhere to the following scheme:
More information about connecting a telephone socket can be seen in the video:
What to look for when connecting a telephone jack
An RJ11 or RJ12 telephone socket has 2 and 4 contacts. They look like small metal forks. The cable is attached between the tines of the plug. All devices are fixed to only two contacts. Professionals can use a crossover knife for fastening, but in a domestic environment, a regular kitchen knife will do. It is not at all necessary to spend money on a special tool if you have to make the connection once or at most twice.
The braid is removed from the cable by about 4 cm. In this case, the cores should be moved apart from each other.
Many do not buy modern RJ11 sockets, since there are components from the Soviet period. Here are some of the conventions that will probably come in handy:
- RTShK is the Soviet standard. Now such devices are no longer produced, but the telephone set can still function today with their help. They have 4 contacts and a key;
- KSPV - copper-based wire, consisting of one core. It is covered with polyethylene insulation. In most cases, this cable comes in a standard white color. It is used for internal laying in a house or apartment;
- TRP is a distribution cable designed for laying a telephone line. This wire is single pair, which consists of a copper core insulated with polyethylene. Has a separating base.
How to work according to the scheme
So, most professionals work while connecting the phone according to the scheme. If you are using an old standard device, and not a European one, it is better to buy a universal socket. It houses a modern connector and four-pin connector. The fifth is a plastic tongue. The connection of the old type socket is the same as described above with the RJ11 or RJ12 connection. The two wiring wires connect to the pins located near the plastic tab.
It is important to know! Before connecting the outlet, make sure that the plug, suitable for the device, is inserted in a mirror image onto the same pins as in the outlet.
In addition to the listed RJ11 and RJ12 standards, there is also the RJ25 standard. It is equipped with six contacts. Such sockets are not installed at home, but there are situations when unknowingly they are nevertheless purchased. If this happened, then the telephone set will need to be connected to the third and fourth contacts, as shown in the picture:
There are red and green wires connected to these pins, so they will be easy to find. Standard cables are connected to sockets of any subtype.
As we can see, there is nothing complicated about connecting a telephone socket on your own. Good luck!

How do I connect a telephone jack?
The installation of information switches on the one hand may seem easier than electrical lines. After all, they do not have a voltage of 220/50 dangerous for human life. But the installation and connection of a telephone socket is not as simple as it seems at first glance. This is due to a wide variety of stationary devices that 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 socket for a phone with your own hands, providing all the necessary diagrams and photo examples.
Types of connectors
Below are the varieties of new connectors:
Step-by-step installation instructions
So how do you install and connect your phone jack? First of all, you need to check the presence of the device connection diagram. From the tools you will need a screwdriver, an electric drill, and the telephone socket itself.
Note: In working condition, the line voltage may rise to 120V. Therefore, in order to limit yourself from such unpleasant moments when installing and connecting the telephone socket to the network, it is better to use dielectric gloves.
Before proceeding with the installation, it is necessary to de-energize 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 veins. After all, if they are damaged, they will break easily. You need to strip the cable 4 cm in length. Read about how to remove the insulation from the cable in our article.
Use a tester to determine the polarity of the conductors. Typically, a telephone jack has a red positive lead and a green negative lead. But it is better to check, since it is not known how the installation and connection was carried out. If the device was not at hand, then 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 that, a telephone socket is fixed on the wall. After installation, you need to connect to the network and test installed device.
It should be noted that the housing can also be of the buried type. How to install and connect a hidden phone socket? First of all, it is necessary to apply markings on the wall where the device will be installed. Using a punch, make a hole and fix the structural elements with self-tapping screws. Installation ends with fixing the protective housing and testing the fixture that has been installed.
If at home it is necessary to install and connect a socket for a telephone with 2 outputs (installation of several devices with different phone numbers), then one nuance should be taken into account - installation takes place with a large number of conductors. But in general, there are no significant differences in work.
Connection diagrams
The polarity determination technique without an instrument has several advantages. It has been tested more than once. There are many options for color-coding wires and when installing and connecting the device, there is a possibility of further confusion.
The telephone socket is installed according to certain schemes. Such a scheme is developed in advance. As a rule, polarity does not really matter. But some telecommunications devices can fail or malfunction if not taken into account. The device connection diagram is provided below:
In order to simplify the installation, manufacturers carry out the marking of the contacts (the diagram and designation must be attached to 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 with a specific color.
How the conductors of twisted pair cables are correctly labeled when the socket is installed and connected is indicated in the tables below:
Well, the last thing I would like to provide you with are useful tips for connecting a telephone socket with your own hands. So, consider the following nuances during installation:
- To date, the most popular is the internal phone socket. Since it is able to harmoniously fit into any interior of the room and it is not very noticeable. But when installing it, it is necessary to take into account that the wall decoration may be damaged. And more time to spend.
- You should buy products from trusted manufacturers. These include the Legrand and Vico companies. After all, they have already proven themselves positively in the modern market.
- If the numbering of contacts was not indicated on the case of the purchased device, then you must 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 the installation of just such a device is carried out, then you need to know these rules. For example, black, orange, and green are used for plus. For the minus - yellow, blue and red.
So we examined the technology of installing and connecting a telephone socket to the line. We hope the information provided helped you do the installation yourself!

Connecting the telephone socket
To connect a landline telephone to the line, you need a working line from the PBX and the ability to connect a telephone to it. Phones 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 dedicated lines. In apartments, the most often used socket is the RJ 11 standard. How can I connect a telephone socket of this standard myself?
Equipment types
With the development of technology, telephones are being improved, but in general, the principle of their operation remains unchanged. To connect them to the communication line, they still use special sockets.
In Russia, from the 80s and until recently, a single standard was used - RTShK-4. Earlier, wires were connected by simply twisting them together. Now there are several standards.
The development of microprocessor technologies led to the replacement of RTShK-4 sockets with others - with the RJ marking. With their help, you can connect up to four telephones to the line. The abbreviation RJ stands for Registered Jack. With this designation, there are several standards for telephone sockets:
- RJ 9 - connector that connects the handset to a landline telephone,
- RJ 11 - it is he who is most often used in residential buildings and apartments, the first standard adopted in the United States, 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 this work to specialists.
- RJ 45 is a device with 4 pairs of contacts, with its help they 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, this is how Legrand products are designated - RJ11 or RJ 25. Devices of the TAE type are used to connect German and French telephones to the line.
Installation methods
Telephone sockets can be mounted in an open or closed way. 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 tucked into a cable channel located in the baseboard or on the wall. You can find cable channels in different colors and sizes, skirting boards with a cable channel inside. Models with snap-on covers are convenient. There are also skirting boards with built-in sockets. When buying them, choose the ones with the bezel adhering well to the base, otherwise it will lag behind over time.
Sometimes devices are not mounted on the wall, but on the floor. When connected in an open way, they can even be glued onto 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. Sometimes the wires are laid in the wall and the outlet is installed outside. Most often they use a single-core copper cable KPSV in a white polyethylene sheath or also 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
The telephone socket consists of several basic elements:
- housings made of dielectric (non-conductive) material - ceramics or plastic,
- contacts - spring-loaded brass parts, which are needed for reliable connection of conductive parts and uninterrupted current flow,
- terminals - adapters for connecting cables.
The device's contact sockets are recessed into the housing. This arrangement prevents accidental short circuits.
Telephone sockets can be single or multi-plug. Single-socket models allow you to connect one telephone set, multi-socket - several. The RJ 11 socket is a single-plug socket, with its help only one telephone can be connected.
RJ 11 connection
RJ 11 has two wires, so it's easy to do 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 they are in a mirror image in the plug and in the socket. For installation you need:
- twin-core cables 0.3-0.5 mm thick,
- screwdrivers - flat or Phillips, depending on the type of screws, with an insulated handle,
- drill,
- stripping tool,
- tester,
- a tool for crimping contacts - you can not use, 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 outlet must be carried out with rubber or latex gloves. The voltage in the low-current network reaches 60 V, decreasing to 12 V when the phone is picked up. If they try to call the phone, a voltage of 120 V will appear in the wires, that is, it can shock. With this tension it is not dangerous, but unpleasant.
First of all, you need to turn off the electricity. Next, it is necessary to clean the insulation from the wires. This is done with side cutters, pliers, or a regular knife. It is necessary to release the wires from the insulation carefully so as not to damage the very core of the telephone cable, otherwise it may break in the future.
Do not burn the insulation and then peel it off with your fingers. Hot plastic can burn yourself, in addition, with this method, the insulation is difficult to remove accurately. You need to strip the wires at a distance of 4 cm from the end.
It is advisable to strip the wires with a margin: they are thin and fragile, they are easy to damage. The excess part, if it remains, can be easily hidden under the socket housing. With a closed installation, for convenience, the wires are made protruding from the wall surface by 5-8 cm.
Next, using a tester, check the polarity of the wires. Typically, in telephone sockets, 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 the tester, then connect the cables according to the diagram that is attached to the device.
To check if the line is working, you need a voltmeter (multimeter). The line voltage should be 40-60 V.
After that, the wires are connected to the outlet according to the diagram. To do this, you need a screwdriver - the wires are inserted into the connectors and the screws are tightened, clamping them well.
If you need to install the outlet in a closed way, then first a markup is applied to the wall, showing where the device will be located. Then, according to the marking, holes are made using a perforator and the structure is fixed with self-tapping screws. A protective casing is installed on top. At the end, the device is also tested.
If you are mounting a new point and there is no place for the sockets on the wall, then first a recess is made for them - a socket. It is drilled using a special crown-bit on a perforator with a diameter of 6-7 cm. Also, using a perforator, channels for laying wires are channeled. If you don't have a hammer drill, you can do it with a hammer and chisel. But such work is much longer and more laborious.
After that, install the device in a socket box, making sure that the cables do not intertwine. Then the socket is secured with self-tapping screws and spacer screws. The gaps between the socket and the wall are covered with plaster 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 schemes. Their wires are marked with color or numbers, there are different options, but the telephone socket connection diagram is usually attached to the device.
Polarity is usually not that important, but individual devices may malfunction if not respected. The connection diagram is shown in the figure.
The twisted pair conductors are also marked according to different standards, which are shown in the tables. There are old, new and German schemes.
To properly connect your phone and get a well-working line, you need to take into account some recommendations.
- Most often, an internal (hidden) outlet is installed. It fits well into any interior, but it is more difficult to install it, in addition, it can damage the decorative wall decoration. Open-type sockets are easy to maintain, install and dismantle, during their installation the finish does not deteriorate, but they do not look very aesthetically pleasing.
- You should give preference to products from well-known manufacturers. These include firms Legrand and Vico.
- If the outlet 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 has the same color as the negative one, but with the addition of white. In 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 the RJ 25 model. This is undesirable, but if you accidentally bought the 6-pin version, 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 telephones of the old standard. You can also use an adapter from an old standard to a new one.
Conclusion
Using the diagrams and recommendations given in the article, you can independently install a telephone socket of a 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 buying, and when connecting the outlet, carry out the work carefully and observe the polarity.

How do I connect a telephone socket myself?
The telephone socket is inherently a low-current type of socket-outlet devices, the main functions of which are:
- Connecting wired and wireless devices to the appropriate network and providing telephone communication.
- Connection of modems and faxes.
- Connection and organization of work of mini-automatic telephone exchange.
It is much easier to connect a telephone socket in practice than an electrical version. However, this process still requires caution and accuracy, since for its implementation it is necessary to perform a number of electrical work associated with high voltage.
Installation and connection of such devices is ideal for people with little experience in this area, or beginners who are just gaining relevant experience.
Previously, this process raised fewer questions, since there was a single standard governing the installation of such devices. Today, there are several European standards called Registered Jack (RJ). There are several different ways to connect telephone sockets, this process can be done 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 RJ-11 and RJ-12 standards, they have the following connection nuances:
- The design of the device may include 2-4 contacts, which are small metal plugs. Between these elements, the cores of the supply wire must be buried.
- The connection of the telephones themselves takes place exclusively through 2 central contacts.
- For the installation of devices with the specified standard, professional craftsmen use a special type of working tool called a crossover knife. However, if in the future its frequent operation is not planned, then you can limit yourself to the most ordinary knife with a sharpened blade. Such a tool is used to deepen the cores; when cutting the insulating layer, contact will be ensured.
- Before straightening the veins, it is necessary to remove the outer layers from the wire, 4 cm is enough to carry out such a stripping.
- For internal installation, it is recommended to use the KSPV cable, which has a single-wire core in its design, which is most often made of copper. The outer casing is usually made of white plastic compounds. The TRP cable is most often used as a distributor.

Required tools and materials
Different tools and materials may be required depending on the type of telephone jack and the standard used.
- A screwdriver that, in terms of the type of work surface and dimensions, corresponds to the screws used to fasten the fixture. The screwdriver handle must be insulated to avoid electric shock.
- Socket box.
- Cable, if not replacing the old device, but laying a completely new one.
- A puncher, as well as a cable, will be needed if a new outlet is being installed.
- The outlet itself.
- A knife with a sharp blade.
- Self-tapping screws.
- Nippers.
- Insulating tape.
- Universal multimeter or tester.
- Protective gloves.
- Single-sided and double-sided adhesive tape.
- A graphite pencil and a brightly colored marker, which you will need for your markings.
Step-by-step instruction
Initially, a simple way of connecting a universal telephone socket will be discussed. Today, the most common devices are those that comply with the European RJ-11 and RJ-12 standards.
In order to connect them, you must adhere to the following algorithm of actions:
- Initially, you will need to disconnect the power supply and wear protective gloves, since the voltage in the telephone network is 60V, and in working condition it can reach 110-120V.
- Using side cutters, remove the insulating layer from the conductors, while it is important not to touch the cores themselves. The stripped cable should be about 4 cm long.
- Using a tester, determine the polarity of the contacts.
- Connect the conductors to the contacts. In a telephone jack, the red wire is negative and the green wire is positive. It is not necessary to follow the connection rules, taking into account the polarity, but there is a certain risk that in the future the telephone set will give its own from time to time during operation.
- Connect the cable cores, then tighten and ensure reliable fixation using special screws for clamping.
- Some models 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.
- Carry out fixation and fastening of the telephone socket on the wall surface. This can be done with double-sided tape, but the most effective way is to use self-tapping screws.
- Snap the cover of this tool.
There are significant differences only in the process of their installation and are as follows:
- Mark the future location of the telephone socket on the wall surface.
- Previously, you will need to make a hole in the surface using a punch, it will be needed for the subsequent installation of the socket. Fixation and fastening of this element is achieved through the use of self-tapping screws.
- The device can be fastened inside the back box using special-purpose spacer screws.
- Put on the outer protective case, 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 kind of telephone sockets may not be the usual single, but double devices. Such devices are usually installed in offices or other premises where there are several telephones with different numbers, but sometimes it may be necessary to install them at home.
The installation or connection process does not fundamentally differ from work carried out with a single design. The only change is the increase in the number of wires that need to be connected.
Types of telephone sockets
When considering different types of such devices, one of the main classifications is their division according to the method of installation:
- Devices for external installation.
- Devices with internal wiring.
A secondary classification applicable to both types is the division of these devices according to the number of available connectors:
- Single-socket models are designed to connect 1 device; they are the most popular option for installation in private houses or residential apartments.
- Multi-connector models allow you to connect several different devices at once, most often found in offices and business premises.
Also, on the modern market there are sockets with different connectors.
RTShK-4 This parameter is determined by the type of standard used:
- RJ-11 is one of the most common options, it implies the presence of 2 conductors in the structure. Such devices are most often found and are recommended for installation if there is a line-type telephone trunk to which the device is connected.
- RJ-12s are less common because they are rarely used for domestic purposes. The main purpose is to connect to office mini-automatic telephone exchanges or a number of types of network cards.
- RJ-14 has 4 conductors and the same number of contacts in its design. 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. In plug-on sockets, you must use a green and red conductor, which are usually located in the center of the fixture.
- RJ-25 includes 3 pairs of working contacts in its design. Devices of this type are extremely complex and unsuitable for self-assembly. To carry out this process will require the involvement of a qualified specialist who understands electrical and telephony issues.
- RJ-9 is a special kind of connectors, the main task of which is to connect the handset directly to the device.
- RTShK 4 is already a technically outdated type of sockets, which were widespread in the USSR in the past; 4 wide contacts and a key are included in the design. Designed for a specific connection option in an all-in-one 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.
telephone wire marking All the main issues related to the installation and connection of telephone sockets have been considered, summing up, you can give a number of the following useful recommendations:
- The most popular today is the built-in type of devices, since it harmoniously fits into any room and is an extremely invisible element. However, it must be borne in mind that its installation will take more time and the wall decoration will suffer.
- It is best to purchase devices that were produced by well-known and proven manufacturers who have managed to positively recommend themselves in this area. Today, such companies are Legrand and Vico.
- On some models, the numbering of contacts, which is usually applied to the body of the fixture, may not be available. In this case, knowledge of the rules of color coding can help: green, orange or blue combined with white are used to indicate positive contacts; the same colors, only monotonous and without added white, indicate negative contact.
- If an old-style telephone socket is being installed, then it does not hurt to also know the color coding rules that were used earlier: orange, black or green conductor is positive; red, yellow or blue conductor must be negative.
During the development of communication facilities, several standards have been created for connecting stationary telephones to existing lines. Almost all of them are used to one degree or another 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.
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 existing communication lines, created by a stationary part - a socket or "mom-contact" and a movable plug inserted into it: "dad-contact".
Design features
Any electrical outlet for communication systems consists of:
1. Stand cases made of dielectric materials: plastic or ceramic;
2. spring-loaded metal contacts that ensure reliable passage of network currents into the telephone set through the plug and cord;
3. terminal clamps providing connection of wires from a fixed network.
All these devices are referred to as low-current circuits. They can be manufactured for installation:
1. in a way hidden in the wall;
2. overhead method.
Installation features affect the types of installation and connection of sockets, which must be taken into account, combined with the design of the telephones used.
Features of the main standards
For the telephone line, only two wires were previously used, creating a closed circuit for the current path, and inside the socket, two contacts were also used to connect them.
If you cut off the plug and socket and twist or otherwise connect in pairs the metal wires of the telephone set and the working network, and then wrap it with a layer of electrical tape, then the connection will work. This principle was used to create a permanent connection through a special tap-off box.
It works reliably even now. Only for its implementation modern designs of contact systems and reliable methods of their isolation from harmful environmental factors are used.
In modern conditions, there is an integration of low-current circuits, telephone line systems and computer networks. The equipment for them is constantly being updated and modified.
Inside low-current systems, sockets are installed, created according to different RJ standards with several pairs of contacts. They have the technical ability to connect a telephone set. This is often used by specialists, using only two contacts out of all available.
An overview of typical models of detachable connections, their types are shown in table 1.
Low Current Connector Standard Types

Differences between connectors
RTShK-4 - telephone socket for four contacts for plug connection with a capacitor
The standard has been in operation since the eighties. The plastic housing of the plug and socket has a dielectric key, which excludes incorrect connection of the electrical circuit.
When several telephones were installed on one line, the corresponding number of parallel-connected RTShK-4 sockets was created. A capacitor with a capacity of 1 stu 1 μF was mounted at the end of the line to conduct technical tests and creating busy line effects on the caller's side.
RJ-11 connectors
Now telephones, sockets and plugs are equipped with an RJ series connector, which has the same housing, dimensions and design for connecting one, two, three or four pairs of electrical circuits. However, they can be supplied with different designs of plastic locks with special cutouts, which exclude the installation of separate RJ11, 14, 25 plugs into RJ45 connectors.
They must be taken into account when connecting various manipulators. Otherwise, you may not learn electrical contact or even break the connector, break its body.
The RJ11 interface is designed exclusively for a two-wire telephone line. It can be used not only for one telephone, but used by several devices assembled into blocks for various devices.
The RJ11 connector is widely used not only in stationary models, but also to connect the base of radiotelephones, allowing you to talk at a certain distance from it due to the technology of radio transmission of signals between the handset and the base over the air using an electronic receiver and transmitter.
Combined RJ-11 connectors with RTShK-4
The method of connecting telephone sets through combined adapters equipped with combined connectors is implemented in a composite design that simplifies installation with an additional accessory.
RJ-14, RJ-25 connectors
Their appearance corresponds to the previous RJ11 design. The difference lies in the number of contacts and possible differences between plastic locks.
RJ-45 connectors
They are designed for low-current circuits with four pairs of contacts, allowing the use of circuits for connecting complex communications and computer systems used in modems, laptops and other similar devices.
Methods for marking switching circuits
The contacts of the sockets are connected in accordance with a previously developed diagram. The design of the telephone set most often allows disregarding the polarity of the connection. However, for some devices this is technically unacceptable: they may not work correctly or fail.
To facilitate installation and troubleshooting in the circuit, manufacturers mark the contacts. It can be carried out:
1.application of numbers near the contacts or their designation on the wiring diagram:
2. highlighting wires in a certain color.
In practice, there are several ways to switch wires. They are shown in tables 2, 3, 4.

Connection diagrams for telephone sockets and plugs
Let's analyze the issue using the example of the RTShK-4 connector, which is used for communication not only with the end subscriber, but also for an additional line - communication between the secretary and the director.
One pair of contacts is used for the line coming from the PBX, and the second is used for organizing additional communication via the service channel.
The diagram shows the installation site for a 1 μF capacitor with an operating voltage of 160 volts. Now they refused such a connection, they stopped installing the capacitor. This practically does not affect the quality of communication.
The designs of the RTShK-4 connectors are already outdated. They are gradually being replaced by new, more convenient devices that take up little space. But, the wiring diagram has not fundamentally changed. For one telephone to work, it is still enough to simply create a closed electrical circuit with a two-core PBX line.
It is customary to combine modern telephone sockets into consolidated blocks used in combination with other communication devices: computer equipment, fiber-optic cable networks, electrical devices.
Such blocks are concentrated in one convenient place for maintenance and hidden from prying eyes.
Hazards of the telephone network
No matter what the "experienced" communication electricians who were "beaten" by the voltage of the automatic telephone exchange line, safety issues must be paid attention to.
The telephone socket is usually connected with the resting voltage of the communication line. Its value is about 60 volts. If you manage to catch the moment incoming call, then a variable sinusoid with an amplitude of up to 120 volts passes through the network.
It may well create a current path through the body of the connecting master. If the hands are wet or sweat appears on the body, then the conductivity will increase dramatically. The painful sensations will become very unpleasant, they will cause convulsive reactions. It is better to avoid them by protecting your hands with thin dielectric gloves and observing other technical measures of safety rules.
Methods for installing telephone sockets
Taking into account certain technical points, telephone sockets are mounted in the same way as ordinary electrical ones. These points have already been described in the article:. Check it out: preparation and fastening methods for open and closed wiring systems are already disclosed there.
You will also find useful material on this issue in the article for the installation of electrical wiring and low-current circuits. This method is used when the repair is finished, dirty work cannot be done, and telephone wiring must be laid nicely and neatly.
Modern plastic cable channels can be selected for any room design. They are equipped with numerous accessories including electrical and telephone sockets.
Thus, in order to install and correctly connect a telephone socket, it is necessary to select its model in terms of dimensions and technical specificationscorresponding to your telephone set, as well as take into account the recommendations set out in the proposed material.
