How to connect a telephone wire. How to connect a landline telephone to a communication line, connect the wires to the socket

Rostelecom offers all its clients a home phone connection on the most favorable terms. To ensure the greatest convenience in using landline communications, the operator company has developed the most simple system installation of telephones and offered subscribers a range of tariff plans, allowing everyone to choose the most optimal option for themselves.

To connect home phone from Rostelecom, the company’s clients can use one of the following methods:

By phone

Another option: use the capabilities of the autoinformer (8-80010-02525). The person who made the call will only need to listen to all the instructions and then agree to automatically conclude a contract.

The last method involves using a telephone: filling out an application for a call back online (www.rt.ru/fastorder). From the information, the user will need to indicate: his name, contact phone number and installation address. After some time, specialists from the support center will contact the subscriber to confirm the order and clarify some significant points.

Via the site

You can also conclude a connection agreement via Personal Area, but for this you will need to register on the site. The further scheme, as in the previous options, assumes that later the specialists themselves will call the user.

Personal office visit

You can connect your home phone by contacting the employees of the nearest company office. The sales center is convenient because there you can immediately discuss in detail with Rostelecom employees how to connect the phone, how much it costs and get answers to other important questions, as well as immediately decide on the most suitable tariff plan.

Each of the options has its pros and cons, so everyone decides for themselves which method they will use.

Application Form

When filling out an application, one of the main questions that concerns the subscriber is the price of connecting a home telephone. Fortunately, for Rostelecom it is noticeably lower than for other companies: approximately 10,000 rubles per normal installation and about 1,300 thousand rubles for connecting legal entities.

This figure will differ in different localities, but only slightly. This amount includes in advance the cost of a standard device that will be installed in the subscriber’s home (it functions equally well when connected to the network and to a battery).

Therefore, before connecting your home phone to Rostelecom, it is recommended to immediately clarify how much this service costs. And only then, if it turns out that all the conditions offered to the user suit him, you can start submitting an application. To do this you will need to provide the following information:

• your full name;
• mobile contact number;
• passport data;
• postal address (where you need to place your phone number).

Submit your application in any convenient way (this will not affect the cost of the service provided) and connect a Rostelecom landline phone.

Important! To conclude an agreement, the subscriber will need to present a passport or other identification document.

Selecting a tariff plan

The cost of connecting a home phone from Rostelecom will depend on which tariff the subscriber has chosen:

Subscriber

The tariff is provided only for those users who do not have per-minute determination of call duration (due to the lack of appropriate technical capabilities). These subscribers, for 344 rubles per month, get the opportunity to talk for an unlimited time (subject to making calls to local numbers). This relatively small amount even includes telephone line maintenance fees.

Unlimited

This option is designed for those who like long conversations, so the duration of calls on “Unlimited” is not limited. The cost of connecting to a Rostelecom landline telephone tariff is 512 rubles monthly. The service is valid only for calls to local numbers. Communication with other regions will be charged separately.

Combined

For 320 rubles, users of the “Combined” tariff receive 350 minutes of free calls with local numbers every month. The line fee is also immediately included in this amount. Conversations over the established limit will cost 44 kopecks per minute.

Social

Rostelecom's tariff with the lowest monthly fee (236 rubles) allows you to compensate for the cost of providing a line and gain the right to make free calls for 100 minutes every month. Once the limit is exhausted, the subscriber will have to pay 60 kopecks for each minute.

Day off

The cost of connecting to the “Weekend” tariff for a Rostelecom home phone is 338 rubles/month. Its special feature is the ability to conduct unlimited long conversations during holidays and weekends. The rest of the time, calls must be paid at a rate of 50 cpm.

Time-based

The latest tariff is intended for those who use their home phone only in the rarest cases. To pay for it, you need to pay 204 rubles every month (this is compensation for maintaining the line’s activity). Each minute of conversation on the “Time-based” tariff is 54 kopecks.

It is necessary to take into account that the tariffs, depending on the region of residence of the subscriber, will have some differences, so it is impossible to say in advance exactly how much it costs to connect to the service in each individual case.

Equipment installation

An application for installation of a Rostelecom phone is considered no longer than three days, and installation of all necessary equipment takes no more than 40 minutes. During this time, the technician manages to install the socket (to minimize the cost of maintenance, it is presented in a single copy) and establish a connection between the Rostelecom landline telephone and the network.

The client purchases the main device and the elements needed to secure it himself (this is included in the connection price). And the specialist delivers the socket, cable and other elements necessary for installing the Rostelecom phone himself and no additional fee He will not demand for this.

Obviously, there should be no difficulties with submitting an application, concluding an agreement and subsequent installation of the device. Therefore, connect a landline phone, test the capabilities of Rostelecom landline communications yourself and enjoy the communication.

Telephone is an electrical device that allows people to exchange information over a distance using an electrical signal. The word telephone came to us from ancient Greece. Tele is translated as “far”, and background is “voice”.

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

What is the voltage in the telephone line

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

It is impossible to damage the communication line or damage the telephone 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 switched off by an automatic telephone exchange (PBX) to save energy. So you can safely start self-connection telephone to the communication line.

Before you connect landline phone, fax or radiotelephone to the communication line, it is advisable, but not necessary, to check whether the communication line is ready. The 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 handset is on the phone, the device should show a voltage of 40-60 V. If there is no voltmeter, you can check using a potato, and this is not a joke, but a real way to check. It is enough to stick the noodle wires, stripped of insulation, into the cut of the potato. No batteries are needed since the wires are already energized.

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

The PBX is equipped with a protection system against failure of equipment and communication lines, which limits the current during a short circuit of the telephone line to 40 mA.

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

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 landline telephone service 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 more modern circuits 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 you need to install several telephones for 1 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. The 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, and damage and ensure a reliable connection between the telephone set and the 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, which is mounted into the wall, to install it you need to make a recess, as well as a hole for laying the cable.

First, a wire is connected to an outlet of this type, after which the box is installed to the wall using dowels and self-tapping 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 poorly 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 telephones. 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.

All work is best carried out in rubber gloves, although the voltage is telephone network small, but if called, 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.

For more than a century, people have been communicating at a distance using phones, the designs of which are constantly being improved and modified.

Modern models differ from their predecessors in ease of use, aesthetic appearance, and reliability.

However, the operating principles laid down in the first designs remained the same:

• mandatory presence of a valid communication line from the telephone exchange;
• electrical connection to a landline telephone.

Telephone socket functions

The socket and plug are in a modern way connecting the telephone to the communication network. Their task boils down to reliable and rapid creation fixed connection.

The electrical contact sockets of any outlet are always under line voltage. To protect against accidental short circuits, they are recessed into the housing. The plug contacts are exposed and isolated from the environment only after installation.

Design features

The common elements of any telephone socket are 3 parts:

1. housing made of dielectric material based on plastics;
2. terminals for connecting communication wires;
3. spring-loaded brass contacts that create an electrical circuit.

Telephone sockets and plugs operate in low-current circuits and are manufactured taking into account the voltage operating in them up to 120 volts. They can be used:

• hidden inside the wall with a closed method of laying a telephone line;
• openly - in an overhead way.

The type of installation affects the room design and service conditions. It is taken into account when connecting the phone specific model.

Telephone Jack Standards

As phones have improved, the way they connect to a communications network has undergone several technical developments.

Old standards

In the first telephone sets, sockets were not used at all to connect them to the line, and the wires were simply twisted together or connected by others available methods. For the phone to operate, it is enough to create a closed current loop, which is formed by only two conductors - current-carrying cores.

This method works quite reliably for any model. The plug and socket can simply be cut off, and the wires twisted and insulated. Communication will be ensured.

In the eighties of the last century, the RTShK-4 standard for telephone sockets and plugs began to be introduced in the USSR. To connect to the PBX line, a two-wire copper wire, called “noodles” in signalmen’s jargon for its appearance.

This method reliably provides a quick disconnect to your phone.

The abbreviation RTShK-4 stands for a telephone socket with four plug-type contacts and an additional capacitor. To prevent incorrect installation of the plug into the socket, an additional plastic connection is created on their cases - a security key.

Socket connection diagram

RTShK-4 includes two pairs of contacts, not one, which is quite sufficient for operation regular phone.

The second pair allows you to connect an additional communication line with one more subscriber according to the principle of communication between the director and the secretary, when one telephone number is used on two devices.

In order for the phone to work, it is necessary to connect the wires to the socket in such a way that the telephone exchange current passes through its contacts with the plug to the telephone set. Older models did not require polarity.

A 1 µF capacitance was used to conduct network tests by telecom operators and generate a busy signal. It was installed only on the terminal device when they were connected in series.

Now they have abandoned the use of a capacitor in an outlet. This does not affect the quality of communication.

Telephone sockets of the RTShK-4 series take up a lot of space. They are morally outdated, although they are successfully operated and are improving their resource.

Modern standards

As a result of the rapid development of microprocessor technologies and the creation of standardized equipment for them, plug and socket housings for low-current circuits, marked with RJ symbols, were put into operation. They allow you to connect up to four pairs of working contacts into the circuit and are produced according to the standards described in Table No. 1.

Table No. 1. Standards for Low Current Circuits

Brief descriptions of connectors

RJ-11 connector

The housings of modern landline telephones are connected by sockets and plugs with one pair of contacts. They are mounted inside a plastic module of a single design of the RJ series and are designated RJ-11.

The brass contacts, as seen in the photo, are located in the center of the plastic module called the manipulator. The remaining places on it are free. Through these contacts on the plug and socket, an electrical circuit is formed between the PBX station and the telephone.

Using the RJ-11 interface, you can connect not one device to the network, but several. To do this, it is enough to assemble the sockets sequentially into blocks, as shown in the photo below.

Combined connector RJ-11 and RTShK-4

The telephone connection method is based on the use of an adapter that combines the capabilities of connecting plugs of old and new standards with lines equipped with modern technologies. This module is convenient to use when an exclusive old phone needs to be connected to new telephone wiring and fit into the interior design.

Connectors with two and three pairs of contacts RJ-14, RJ-25

This standard of manipulators for communications means can be used to operate a telephone. You just need to use the two middle contacts that are already used in the telephone socket of the device.

At the manipulators different manufacturers There are different types of plastic locks. In this case, you cannot insert the plug into the socket: you can destroy the fragile case.

RJ-45 connector

It has four pairs of contacts and is designed for computer systems and devices, complex communication devices.

The RJ-45 connector interface allows it to be used for a telephone set. Electric circuit again it is required to create through middle contacts. But at the same time, it is necessary to pay attention to the compliance of the plastic keys.

Methods for marking low-current sockets

The position of each contact in the connector must be taken into account and marked for convenient installation and repair. For this purpose, markings are created:

1. numbers next to the contact or designation of its position on the installation diagram or factory drawing;
2. coloring the wire insulation in strictly designated colors.

Manufacturers of telephones and pointing devices produce products labeled in several ways. They are summarized in tables No. 2, 3 and 4.

Table No. 2. Color coding of twisted pair wires for low-current sockets

Table No. 3. Old color coding of wires for low-current sockets

Table No. 4. German color marking of wires for low-current sockets

Methods for connecting modern telephones

All the tables above show that the phone is connected to the network according to the old principle: through two contacts. It’s just that modern manipulators use middle contacts, and the rest are not used.

For design and ease of use telephone sockets It is customary not to place it separately on the wall, but to combine it with other electrical units and low-current circuits.

They can be built inside elements of wall furniture or covered with paintings or technical devices: monitors, televisions.

Hidden dangers of the telephone network

For low-current communication devices, a lower voltage is used compared to home wiring. But its usual value of 60 volts can still create a current through human hands and cause a lot of trouble. When a call passes through a telephone line, it is generated by an alternating current signal with an amplitude of about 120 volts.

This is enough to cause pain through the dry skin of the fingers, and if the body is slightly sweaty, the muscle reactions will be unpredictable.

Work in an existing telephone circuit must be carried out wearing protective gloves and the developed technical measures and safety rules must be followed.

Installation of telephone sockets

A prerequisite for the operation of the telephone is the reliable passage of current from the telephone exchange line through it. When installing circuits, it is necessary to avoid wire breaks and incorrect connections. For this assembled circuit before connecting must .

General principles The placement of telephone and electrical sockets on the building structures of the rooms is practically no different. They are described separately. First you will need to choose a method for placing telephone wiring: hidden or open, and then perform it.

Protection of exposed wires can be done by placing them in plastic decorative cable channels, which are equipped with many accessories, including telephone ones.

The article material is successfully complemented by a video by the author Revastroy, which shows editing techniques computer socket Viko company. Watch and comment on him and the article.

Connecting any telephone requires preliminary installation of a special socket. Such a device has its own design features and unlike the connector for electrical networks much easier to install. How to connect a telephone socket without the help of professionals?

The structure of sockets is improved every year, but some basic elements remain unchanged:

• plastic or ceramic case;
• clamps – terminals that secure wires;
• connecting contacts are brass parts that are electrically conductive.

To avoid unexpected short circuits, the electrical contact sockets must be located deep in the housing. Continuous operation of the telephone socket can be carried out if there is a working linear connection from an automatic telephone exchange and connecting a stationary device to it.

Old and modern device standards

For improved phone models, updated methods of connecting to network devices. Initially, stationary devices did not require connecting sockets, since the wires were simply connected directly to each other. Thus, the current passed along a closed path.

The first sockets appeared at the beginning of 1980. They called it “a socket for plug-type telephones with four contacts” - RTShK-4. The connection was made with copper wires with two cores.

Over time, RTShK - 4 replaced standard RJ - sockets network interface“Registered Jack”, which was an international standard socket and plug connection.

Modern telephones powered by PBX have various connectors, which are designated by a special abbreviation - RJ11, RJ12, RJ14, RJ25 or RJ45. Each type of device has its own purpose:

• RJ11 – used for stationary devices with a linear connection, has a two-wire connection;
• RJ14 – used to connect two phones to different lines, as well as organize a mini PBX for offices with a four-wire connection;
• RJ25 and RJ12 – required for six-wire telephone models with three pairs of contacts.
• RJ45 - a device for connecting complex equipment - faxes, computer lines or modems.

Mixed connector models are also widely used - RJ11 and RTShK-4. Almost all types of sockets are connected to the network using two contacts. Only in some new connectors, when turned on, the contacts located in the middle are involved. Old and new models are practically no different in size.

Installation diagrams and connection methods

When choosing a method for installing sockets for connecting a landline telephone, the design features of the walls and the design of the room are taken into account.

There are two types of telephone connector installation:

1. Outer. Such open method The installation of the socket is convenient to use, but does not look very attractive. The connector placed on the wall can be easily dismantled for repair work.
2. Closed. The socket is hidden in the supporting structure without disturbing the overall design of the room.

The telephone jack can be connected without the help of a specialist. But still, although the device does not have high voltage, care and safety precautions should be taken when installing.

To protect exposed wires, special boxes are used, which can be made of plastic or aluminum. Such devices are produced both wall-mounted and floor-mounted. The box has double-sided or single-sided panels with latches that can be removed at any time to inspect the condition of the wiring.

To install sockets closed type a signal wire is used - KSPV. It is quite flexible and can be easily mounted in corners. To connect the line, a telephone distribution wire is also used - TRP with a distribution base.

When attaching all protective parts, you should carefully check the reliability of all connections, since accidentally exposed wires not only look unsightly, but can also easily be damaged.

How to connect a telephone socket

Connecting the telephone jack should be done while wearing protective rubber gloves. You also need to take into account that a small voltage of 60 Volts in the telephone socket can rise to 120 Volts during a call over the line. Under the influence of such electric force the person may experience severe pain.

Connecting a socket for landline telephones includes the following procedure:

• preparation of instruments;
• provision of protective equipment;
• removal from cable protective film according to the required length;
• connecting the cable according to the diagram to the box;
• fixing the cores inside the telephone box.
• attaching the connector to the wall;
• installation of a protective cover;
• connecting the plug to the socket.

The instructions included with each telephone socket contain a valid connection diagram for this model.

Carrying out preparatory work

To facilitate the installation of a connector for a landline telephone, it is best to purchase universal devices with a connecting device of four contacts.

Also, to install the socket you will additionally need:

• voltmeter;
• rubberized gloves;
• screwdriver;
• level;
• tape with adhesive tape on both sides;
• knife for working with optical cross-connects;
• needle nose pliers;
• pencil with graphite lead.

If the connector is installed in a new location, you must also have a hammer drill. A special seventy-millimeter crown is inserted into such a device, with which you can make a corresponding hole in the wall.

Stripping the ends of the cores

The telephone cable has a fairly delicate coating. Therefore, stripping the cable requires special care. Initially, the ends of the wires are cleared of four centimeters of protective insulation.

In order not to disturb the wires that are responsible for the quality of the signal, it is recommended to use a sharp blade or a special crossing knife. If the wires are damaged at the slightest level when removing the braiding, the ends with the defect should be cut off and cleaned again.

Connecting the socket wires

A wire in green insulation means “plus”;
red braid – “minus”.

Incorrectly connected poles can cause permanent problems telephone communication. Using a voltmeter you can measure the required voltage. The operating line value should be between 40 and 60 Volts.

All connected wires must be tightly pressed with mounting screws. After installation, a protective cover is placed over the latches or other fasteners. Before closing the socket, make sure that the wires do not cross each other and that all contacts are recessed into the housing.

Installing a telephone socket is quite simple. The main thing is to have all the necessary tools at hand, know the principle of connecting connectors and have a detailed installation diagram indicated in the instructions for the purchased product.
