Connect a telephone line. How to connect phone sockets to the cable correctly? Scheme and features

During the development of communication tools, several standards for connecting stationary telephones to the current lines have been created. Almost all of them are used in one way or another in everyday life and industrial enterprises.

Inside networks of large organizations that exist several decades, you can meet simultaneously working models of various designs mounted at different times. Features of their device must be considered before installing and connecting a telephone.

Appointment and standards of telephone sockets

The main task of the socket is reduced to ensuring the rapidly disconnected and reliable connection of telephone sets to the current lines of communication created by the stationary placed part - the socket or the "mom-contact" and the mobile inserted into it in the fork: "Dad-contact".

Features of constructive performance

Any electrical outlet of communication systems consists of:

1. Housings and supports from dielectric materials: plastic or ceramics;

2. spring-loaded metal contacts that ensure reliable passage of network currents into a telephone via fork and cord;

3. Terminal clamps that ensure the connection of wires from the stationary network.

All these devices refer to low-current chains. They can be made for mounting:

1. Hidden in the wall in the wall;

2. The invoice method.

Mounting features affect the installation types and connect sockets that need to be considered, combined with the design of the used telephone sets.

Features of basic standards

For a telephone line of communication used only two wires, creating a closed circuit for the circuit of the current passage, and two contacts were also involved inside the socket inside the socket.

If you cut the plug and socket and twist or otherwise combine the pairs of metal veins of the wires of the telephone and the working network, and then wrap the layer of the tape, then the connection will work. This principle was used to create a delicate connection through a special tap box.

It works reliably now. Only for its implementation, modern designs of contact systems and reliable ways of their isolation from harmful environmental factors are applied.

In modern conditions, there are integration of low-current chains, telephone lines and computer network systems. Equipment for them is constantly updated, modified.

Inside low-voltage systems, set outlets created by different RJ standards with several contact pairs. They have the technical ability to connect a telephone. This often uses specialists, cycling only two contacts from all available.

Overview of typical models of detachable compounds, their species are shown in Table No. 1.

Differences connectors

RTSHK-4 - socket telephone for four contacts for the capacitor plug

The standard works with the eighties. The plastic housing of the fork and the socket has a dielectric key that excludes the incorrect connection of the electrical circuit.

When installing multiple phones on the same line, the corresponding number of parallel connected RTCHK-4 sockets was created. The 1-stage capacitor with a capacity of 1 μF was mounted at the end of the line for technical tests and creating the "busy line" effects on the side of the caller.

RJ-11 connectors

Now telephone sets, sockets and plugs are supplied with the RJ series connector, which has the same body, 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 that exclude the installation of individual forks RJ11, 14, 25 V connectors RJ45.

They must be taken into account when connecting various manipulators. Otherwise, you can not learn the electrical contact or to break the connector in general, break its body.

The RJ11 interface is created exclusively for a telephone line with two wires. It can be used not only for one phone, but to be applied by several devices collected in blocks for various devices.

The RJ11 connector is widely used not only in stationary models, but also to connect the radio telephones base, allowing to talk on a certain distance from it due to the technology of radio transmission between the tube and the air base by means of an electronic receiver and transmitter.

Combined connectors RJ-11 C RTSHK-4

The method of connecting telephones through combined adapters, equipped with combined connectors is implemented in a composite design that allows you to simplify the installation of an additional accessory.

RJ-14, RJ-25 connectors

The appearance of them corresponds to the previous design RJ11. The difference lies in the number of contacts and possible differences in plastic locks.

RJ-45 connectors

They are created for low-voltage chains with four contact pairs, allowing to use schemes for connecting complex communications and computer systems used in modems, laptops and other similar devices.

Methods for labeling switching chains

Contact sockets are connected in accordance with the previously developed scheme. The design of the telephone is most often allowed not to take into account the polarity of the connection. However, for some devices it is technically unacceptable: they may incorrectly work or refuse.

To facilitate the installation and troubleshooting in the scheme, manufacturers perform contact labeling. It can be carried out:

1. Apply the numbers near the contacts or the designation of them on the mounting scheme:

2. Wiring to a certain color.

In practice, several ways of switching wires can meet. They are shown in Tables 2, 3, 4.

Connecting telephone sockets and forks

We will analyze the question of the example of the RTSHK-4 connector used for communication not only with the terminal subscriber, but also for the additional line - communication between the secretary and the director.

One pair of contacts is involved in a line that comes from PBX, and the second is to organize an extension communication on the service channel.

The diagram shows the place of installation of the capacity of 1 μF with an operating voltage of 160 volts. Now they refused such a connection, the condenser stopped mounted. On the quality of communication, it practically does not affect.

The designs of the RTSHK-4 connectors are already outdated. They are gradually replaced with new, more convenient devices that take up little space. But, the electrical connection scheme has not changed fundamentally. To work one phone, it is still easy enough to create a closed electrical chain with a PBX line of two lived.

Modern telephone sockets are customized to combine into the consolidated blocks used in the composition with other communication devices: computer equipment, fiber optic cable networks, electrical devices.

Such blocks are concentrated in one convenient for maintenance and hidden from an extraneous eye.

Dangerous telephone network factors

Whatever they say "experienced" electrician electricians who "beat" current from the voltage of the PBX line, security issues need to be paid attention to.

Connecting a telephone socket is usually performed under the rest of the communication line. Its value is about 60 volts. If you manage to catch the moment of an incoming call, then a variable of a sinusoid with an amplitude of up to 120 volts passes the network.

It may well create a current path through the body performing a wizard. If the hands are wet or on the body, the sweat sticks out, the conductivity will increase sharply. Pain sensations will be very unpleasant, they will cause convulsive reactions. It is better to avoid protecting hands with thin dielectric gloves and compliance with other technical safety regulations.

Methods for mounting telephone sockets

Taking into account certain technical moments, telephone sockets are mounted by the same methods as ordinary electrical. These moments are already described in the article :. Familiarize yourself with it: there are already disclosed methods for preparation and fastening for open and closed wiring systems.

Also useful material on this issue can be found in the article for mounting wiring and low-current chains. This method is used when the repair is completed, dirty work cannot be performed, and the telephone wiring must be paved beautifully and neatly.

Modern plastic cable channels can be selected for any design room. They are completed with numerous accessories, including electrical and telephone sockets.

Thus, to install and correctly connect a telephone socket, it is necessary to choose its model in dimensions and specifications corresponding to your telephone set, as well as take into account the recommendations set out in the proposed material.

In fact, we are mostly familiar with the telephone socket connection mechanism. In fact, there is nothing hard. If you have basic training or even theoretical knowledge, you can manage half an hour, taking into account the wire laying.

Views of telephone sockets

Are you going to connect the phone? To answer the question about how to do this, you must first decide on the type of socket. A few years ago, this question would not be asked because there was only one type - RTShK-4. In each house where the phone was, it was such standard devices. Today, Soviet rooted standards were changed by European - 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 of office PBX with a numerous number of channels. If you plan to install the phone at home, it is better to navigate to RJ11.

Phone Outlet Mounting Methods

If there are minimal knowledge, you can connect your own telephone network for 5-10 minutes. There are two installation methods - open and closed. Public method implies installation on the surface without removing the finishing layer.

For example, if you have already fully made the repair and now you need to hold a phone, then the outlet is installed directly on the wallpaper or paint. Cable - Channel at the same time hiding under the plinth. An open method of fastening can be carried out, in general, without mounting on the wall - the socket may be located on the floor.

It contains 4 screws. Two, closest to the connector, do not need to touch. The wire is attached in the two remaining screws. Further, insulation - the veins are joined to the climb and pressed with screws. After that, the case cover closes. Work is ready.

It's important to know! All work on open installation should be carried out in gloves. It is better to use latex. There have been cases of voltage when they tried to call the phone. At this moment you can hit the current. The blow will, naturally, not fatal, but sensitive.

The hidden way of installation involves the laying of the phone's wire before the socket is connected. In this case, it is planned to place its location.

Sometimes they hide the wires in the wall, and the outlet is removing out. Visually, this method of fastening resembles standard electrical outlets. Hidden and open mounting methods are called external and internal. In general, the fundamental differences do not exist.

Connecting phone socket RJ11

Before starting to install, you should prepare a basic set of tools and materials:

Modern outlets for phone are produced different sizes and colors. To independently connect RJ11, you need to adhere to the following scheme:

More information about connecting a phone socket can be viewed on video:

To pay attention when connecting a phone outlet

The RJ11 or RJ12 telephone socket contains 2 and 4 contacts. They look like small metal forks. The cable is attached between the teeth of the fork. All devices are fixed only to two contacts. Professionals can use to secure a cross-knife knife, but in domestic conditions the usual kitchen is suitable. It is absolutely not necessary to spend money on a special tool if the connection has to be carried out one or a maximum of two times.

The braid from the cable is removed by about 4 cm. The cores should be separated from each other.

Many do not buy modern RJ11 sockets, as components remained from the Soviet period. Here are some symbols that will probably use you:

• RTSHK is a Soviet standard. Now such devices are no longer available, but the telephone can also function today with their help. They have 4 contacts and key;
• CPVV is a copper-based wire consisting of one vein. It is covered with polyethylene insulation. In most cases, such a cable is produced standard white. It is used for the inner laying in the house or apartment;
• TRP - distribution cable intended for laying a telephone line. This wire is union, which consists of copper veins, isolated by polyethylene. It has a dividing base.

How to work according to the scheme

So, most professionals work while connecting the phone according to the scheme. If you use the apparatus of the old standard, and not European, it is better to buy a universal outlet. It mounted a modern connector and a connector of four contacts. Fifth - plastic tongue. Connecting the outlet of the old type is similar to the option described above with connecting RJ11 or RJ12. Two wiring wires are connected to contacts located near the plastic tongue.

It's important to know! Before connecting the socket, you must make sure that the wires are entered in the fork suitable for the machine, the wires are entered in a mirror reflection on similar contacts, as in the outlet.

In addition to the listed standards RJ11 and RJ12, there is still a standard RJ25. It is equipped with six contacts. Such sockets are not installed at home, but there are situations when the ignorance is still purchased. If this happened, the telephone device will need to connect to the third and fourth contact, as shown in the picture:

The red and green wire are connected to these contacts, so they will be easy to find. Standard cables are connected to outlets of any subtype.

As we see, there is nothing complicated in the independent connection of the telephone socket. Good luck!

If you need to transfer a landline phone from one room to another or replace the available apparatus to a more modern, it will be necessary to produce a telephone outlet.
This operation takes a little time and can be performed independently in the presence of minimal knowledge in the electrics, and the ability to handle the tools.

The operating voltage of the telephone line is noticeably below the 220 volt electrical network, but if you make installation work without protective gloves, you can get a tangible discharge of an electric current, especially at the moment when the connection is currently going on, the incoming call will receive.

For installation, the following tools will be required:

• screwdriver;
• perforator;
• ticks for cleaning wires from isolation;
• a hammer;

Materials may be needed.

• building gypsum;
• uTP cable;

Instructions for connecting

Installation of open outlet

This is the easiest installation option, takes no more than 10 minutes.

Installation is carried out in this order:

1. To sockets 2 wires, stripped from insulation, are reliably clamped.
2. Socket It is installed at the bottom of the wall or on the floor with screws.
3. ForTo hide the outer wiring, use electrical or panels, inside which the telephone wiring is installed.

When installing telephone sockets, polarity should be observed. In the information transmission system by means of a telephone signal, a positive conductor is performed in a green insulation, and the negative is red. But even if during installation, the conductors will be arranged incorrectly, nothing that might harm equipment will not happen, simply the telephone will not work.

Installing a hidden type socket

Installation in this case is more complicated and requires work on the implementation of recess in the wall wall:

1. For this, perforator, with a special nozzle of a suitable diameter, is deepened in the wall in the place where it is assumed to be installed a telephone socket. If there is no perforator, then the hammer and chisel can be done by the same work, but it will take time to it much more.
2. To the installation site You should cut the channel in the wall to lay a telephone cable.
3. Twisted para Connects to the terminals of the socket, by observing the polarity, then installed in the conversion, which is already mounted in the deepening of the wall.
4. Evenly Bolts are tightened, which are reliably fixed, with special legs, an inner outlet.
5. Prepared gypsum solution The gaps between the submerged and the wall are eliminated, and the channel with the telephone cable is also closed.
6. After the completion of the "gypsum" worksThe outlet is installed external, decorative part.

If the old-sample phone is installed, in order to duplicate it with the same device, it will be necessary to install the RTCH outlet - 4. This species refers to the category of external, so its installation is carried out in the method described above.

The difference in modern samples of this type of sockets is that there is no condenser in their designs, with which it used to check the operability of the telephone line.

Today, for verification, a tester is used, which is in the "rest state" should show the presence of a direct current of the value in 60 V. in the absence of a tester or a multimeter, you can connect a well-serviceable telephone device to the line and try to make a call. If you do not succeed, the telephone network is faulty.

How to connect the Legrand phone socket?

The products of the French firm "Legrand" have the highest quality, as well as a feature that facilitates the process of mounting a telephone socket. In order to fix the conductor to the contacts of the socket, it is not necessary to clean the wires from the insulation.

In the design of the outlet, special knives are provided, which produce a cut of insulation when the wire is carried out inside the terminal. For this, it is enough to turn a special clamping mechanism on a quarter of turnover.

After connecting the wires to the logging outlet will be completed, the quality of the contact connection is performed using a multimeter. To do this, you should translate the device into a constant current mode and measure the voltages on the terminals of the socket, which, in the absence of an incoming call, should be within 60 V.

If there is no voltage, it follows the clamping mechanism to rotate in the opposite direction, completely freeing the conductor, then again to stop it clockwise.

Views

Telephone sockets have several varieties:

1. RTSHK-4. - This standard, despite its "antiquity", is used to this day. In modern design, premises does not look aesthetically and, usually, when carrying out a "renovation" changes to more modern options.
2. RJ11 - The most common option of modern sockets for connecting the phone. Uses a two-hind scheme, which greatly facilitates installation work.
3. RJ12 - It often happens a dual type, which allows you to connect two telephones at the same time.
4. RJ14 - Designed for connecting 2 telephone lines, but practically it is impossible to do this due to the presence of only one telephone line in homes, so this socket can be used as standard RJ12.
5. RJ25 - It is practically not used to connect individual telephones, due to the presence of a three-contact connector.

1. Disable the telephone line During the installation work, it is not possible, so when working, be sure to use protective gloves that will help to avoid unpleasant sensations from exposure to electric current. Especially this impact can be significantly in the moments when the incoming call is received on the subscriber's phone, the alternating voltage current can reach considerable values.
2. If planned overhaul In a house or apartment, installing a modern built-in telephone connector will take quite a bit of time, even if at the moment there is no need for it.
3. Do not do it save money and purchase low price range telephone sockets. Such products do not always comply with the quality of product quality, and often fail at the installation stage.

During the development of communication tools, several standards for connecting stationary telephones to the current lines have been created. Almost all of them are used in one way or another in everyday life and industrial enterprises.

Inside networks of large organizations that exist several decades, you can meet simultaneously working models of various designs mounted at different times. Features of their device must be considered before installing and connecting a telephone.

Appointment and standards of telephone sockets

The main task of the socket is reduced to ensuring the rapidly disconnected and reliable connection of telephone sets to the current lines of communication created by the stationary placed part - the socket or the "mom-contact" and the mobile inserted into it in the fork: "Dad-contact".

Features of constructive performance

Materials and tools

The main devices that may be needed when laying telephone wiring:

• sideboards - for cutting cable;
• knife - to stripping the ends of the wires;
• screwdriver - fastening ends in the outlet;
• screws - fixing the base of the device to the wall;
• drill - drilling holes for fixing the external device;
• drill with carbide attacks - as a rule, is used with a diameter of 4.2 mm;
• plastic inserts in holes;
• Bulgarian with a discon's disk - to perform hidden wiring;
• perforator with a crown drill, the size of the drill in accordance with the size of the box;
• - to clarify the polarity of contacts in the connector when connected;
• protective latex gloves - if when working it will randomly be a call to the phone, the potential difference can reach 120V, which is already unsafe with direct contact.

Procedure for performing work

1. If it is decided to install the hidden wiring, you must first run the channel for laying a telephone cable. With the help of the "Bulgarian" to label the channel over the entire length and put the wire into it, the channel is to close with cement mortar.
2. In the manufacture of open wiring, there will be special plastic brackets for fastening the cable on the wall and an electric door with a drill. In the holes of a depth of about 20 mm insert plastic liners, and fasten the wire under the bracket with a nail or screw. All fasteners are sold complete, compatibility problems do not occur.
3. Installation under the plinth will require the use of the chisel, with which the plinth is removed from the wall for laying the wire. After that, the plinth fell into place by regular nails.
4. When installing the outer box, it must be connected to the cable first. After that, fasten on the wall. Here options are possible, defined by the structural execution of the boxes themselves. If its base has holes for fastening, you need to apply e to the place of installation and place the location of the holes on the wall. Taking advantage of the drill, drill holes, install inserts and secure the base of the box with screws from the kit. Then install the lid having special latches for this. The base without fastening holes can be installed on the wall using bilateral scotch. The mount is quite reliably, but when the connector is disconnected, the case is desirable to hold.
5. When installing the inner box, you need to use the perforator and the crown drill to the diameter of the box. After performing a deaf hole in the wall, install the box in it, connect it to the cable and fasten into the hole. Put on the place the lid.
6. When connecting the contacts, you need to check the tester compliance with the poles (the location "+" and "-").

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

The varieties of connectors. Features of the use of RJ11, RJ12 and other species

Telephone connectors serve not only to connect the devices in the communication line. They are used to connect to other devices and communication devices.

Outlets are performed with one, two or more connectors and can provide a connection of several subscribers simultaneously.

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

• RJ11 - two-wire execution, applied to connect to linear type networks.
• RJ14 - equipped with four conductors and four contacts, compatible with most models of modern phones. To connect one subscriber, you need to use the 2nd and 3rd contacts. If you need to connect a few additional lines, you need to use 1st and 4-ykontaktes. If an invoice handset is used, the line connection is made with wires of red and green colors.
• RJ25 - has three pairs of contacts, its connection requires the participation of a qualified telephone specialist.
• RTSHK-4 - heritage of another Soviet period, but are made and applied to the present. It has a special key. Connection is carried out in an inline way with a bended type box. If there are several points of this type in the room, their closure occurs using a condenser.

About devices for connecting RJ11 and RJ12 Talk more:

• The first of these types of products is used for individual connections in ordinary telephone networks.
• The second is used for large loads - in office or publicly available places.

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

For connection it is necessary:

• remove the braid from the wire for a length of 4 - 5 centimeters;
• relieve each cable vein, the number of which is from 4 to 6;
• put all the wiring in the Paste Pastes;
• check the presence of contact between the connector and the phone cable.

Starting the connection must be concerned about the measures without danger when performing work. Be sure to put on rubber gloves that can protect against electric shock.

The general standards of the sockets indicate that the red braid color usually means a positive conductor, and green speaks of a negative denomination. Make sure the tester will help.

Methods for connecting all sockets are identical, but they differ in methods according to the installation methods depending on the execution.

It is also practically an installation of the popular French production sockets such as Legrnd. The product line of this type is very diverse, sockets are available with any installation plant: exterior, internal and any other. Color marking should be European standards and identical in similar products from other manufacturers.

1. In the manufacture of work on the laying of the telephone cable, you need to remember the safety rules:
   • Performing a stroke of a groove for a cable for brick or concrete, be sure to use protective glasses or protective mask for eye protection and face.
   • When drilling holes for mounting the cable or the base of the socket, take the same security measures.
   • Conducting a cutting of material from the stroke channels, from a deaf opening for a socket box, install a protective disk on the chisel, preventing damage to the hands.
   • Work with wiring needs to be produced in protective gloves.
2. If there is no instrument to check the polarity of the wires, use the potato slice. Pick the ends of the wires into the flesh, the pulp surface around the advantage wire will soon begin to darken.
3. Modern outlets are performed in a safe version. However, it is necessary to establish them in an inaccessible place for children.
4. When cleaning the ends of the cable to connect, it is necessary to avoid damage to the insulation of internal wires and, moreover, the conductors themselves. This leads to a deterioration in the quality of communication and the possibility of the breakdown of the line.
5. If an old Soviet dwelling wire is used in the form of a plastic ribbon with wiring along the edges, it is unacceptable to mount it, driven nails between the wiring. This often leads to a cliff of the line when installed. When the nail contact with the wiring can be formed a grounding pair, worsening the quality of communication.

Wearing all the works thoughtfully and neatly, you can successfully cope with the simple task of performing wiring and installing sockets. Be care without a doubt and you will succeed!

Articles and Lifehaki.

Despite the fact that today stationary phones went to history, users often wonder how and where to connect the home phone.

The use of cell phones allows people to communicate without tosing to a specific place. In addition, cellular tariffs are often lower than in stationary. However, some people wish to hold a landline telephone to the apartment.

• Connect the device is easy, but there are certain subtleties, known only by a narrow circle of specialists. To install a home phone, you will need a special outlet.
• The device should be connected to a single rosette by means of a wire ending with RJ-11 connectors. One of the connectors must be inserted into the socket, and the second is in the tube connector.
• The cables located in the outlet are wound on the screws to which the corresponding terminals are connected.
• The installation of the device can be carried out in any place at home, for which you need to stretch the telephone wire to the desired point.
• The features of the multifunctional apparatus should be taken into account: it is usually connected to an electrical outlet, and, therefore, it should be located at the installation site of the device.
• The following option is a radiotelephone connection. This type of device allows without using the telephone wire, set the database anywhere at home.

Certificate of phone connection in the house

1. The stationary tube has a 2-Conductive type of connection that comes from the PBX.
2. When installing a phone having a 4-C-conductive type of connection, 2 wiring (central wiring of green and red tone) is used.
3. When installing the device without applying a telephone socket, you should use the wiring of these colors. The polarity of the wires can not be taken into account when connected.
4. When you connect the device to the network, a signal is distributed, and sometimes, dialing a telephone number, no beep.
5. In such a situation, the problem is in the setting, and not in the connection of the phone. There are 2 types of telephone - digital and analog, characterized by the principles of a dialing.
6. By installing the phone, you must check the setting of the following functions: redirection, call volume level, number, number, night mode, as well as automatic respondent.
7. Due to the wrong configuration of these functions, problems may arise with calls.

If you have not achieved the desired result when using the phone, you need to ask for help from specialists.
