How to connect a cordless phone to a telephone line. How to “cross” a landline phone with a mobile phone, saving on calls. Wired home phone

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 communication line is under a DC voltage of 40-60 V if the telephone is not connected or is connected, but the handset is placed on the telephone set. During a call, the voltage in the communication line becomes variable with an amplitude of up to 120 V. When you pick up the 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. Shutdown may occur telephone line for a few minutes if the handset is picked up 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 connecting your phone to the communication line yourself.

Before connecting a landline telephone, fax or radiotelephone to the communication line, it is advisable, but not necessary, to check that 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.

Brief information about what a radiotelephone is, what they are,

how and at what frequencies they work, tips and suggestions for buyers.

Man has always strived for freedom in everything. Telephony did not escape this fate either. At first the telephone was a landline, and its owner was on a “short leash” near the device. But time does not stand still - radio communication systems are becoming cheaper, becoming smaller and the handset is freed from wires.

The first ones had angular shapes and large dimensions, and the quality and range of communication were at a very low level. Currently, models have already been created that can work in a home, office and even cellular network.

Almost everyone has seen ordinary household ones, with which you can move freely around the apartment, and sometimes even go outside nearby. Everyone already knows what a cell phone is. But about long-range radiotelephones Not everyone knows.

So what is it? Now imagine: you have an ordinary (outwardly) phone at home, you pick up the handset of this phone and go to the other end of the city or even go to another city 5-50 km from your home, and the handset of the phone that you took with you continues work! These are the long-range phones.

So what do we get in the end? We have a regular home telephone, for which we already pay monthly, plus we have mobile phone, for which we pay absolutely nothing! The question immediately arises: Do we need a cell phone?

It is definitely difficult to answer this question. In the current situation with prices for mobile and cellular radio communications in the Moscow region, it is not so expensive to have a mobile phone. Well, how are things in other regions? Naturally, prices are no longer the same, and not everyone can afford to have a cell phone. It’s another matter, having a regular telephone line at home or in the office and installing a long-range radiotelephone, organizing an alternative cellular communications“local radius”. Even forwarding calls from a mobile phone to such a radiotelephone will be more profitable than answering a call directly from a mobile phone, being not so far from a regular city telephone line! After all, a person spends most of his time not on the road, but sitting in the office, at home or relaxing in the country.

Telephone at the dacha

Besides profitable replacement cell phone , often using a long-range radiotelephone is the only and reasonable way to organize a telephone in the country, and sometimes at home, if the Regional Communications Center does not have free lines in your area. Usually this task is solved using 2 telephone line emulators, one of which is connected to an existing telephone line, and the second you install in your dacha or wherever else you want and connect the most ordinary telephone set to it.

Communication with a remote office

By using telephone line emulators mentioned above, it is possible to organize a direct telephone channel between two remote buildings, without using a regional communication center. And again, you don’t pay anyone anything for this channel!

There is often a need telephone some remote object, for example, a country house, a country house, a garage, a warehouse, a store, a car, etc. An extended-range radiotelephone, especially with a directional antenna, partially solves this problem, but often at a remote site it is desirable to have not just a handset, but a full-fledged telephone line to which you can connect a fax, modem, another radio, or a regular telephone or mini-PBX.

By using telephone interface you can get a telephone line (for other devices that only work through it) where there is none, such as a radiotelephone handset or a radio station's PTT button. And then connect other devices (PBX or fax, for example) that will consider that they are connected to an honest telephone line. That is, fully install telephony at objects remote from the main telephone line and connect any telephone sets, FAXES, MODEMs and mini PBXs. Using a certified cordless phone Can legally telephone objects that are inaccessible to the physical line.

Having implemented it at home telephone radio channel, You can transmit data over this radio channel at a speed of up to 32 Kbps (for comparison, hypothetically 9.6 Kbps via cellular; via a regular telephone line, a maximum of 56 Kbps, but realistically 14-38 Kbps, especially in the regions) .

Panasonic is known around the world for its reliable and durable telephone and fax products. Therefore, it is not surprising that many are worried about the question: “how to set up a Panasonic radiotelephone?”

Therefore, we will try to briefly outline the most important functions necessary for the conversation.

Connecting a Panasonic radiotelephone

There is a huge variety of telephone equipment from this company on sale, but all of it can be divided into certain categories, differing in the number of handsets, additional features, and other things. But in any case, all radiotelephones have the same operating principle, therefore, they are connected in the same way. Therefore, below we will tell you how to connect a Panasonic radiotelephone. The first step is to remove the device from the packaging and place it in the required location. The kit will include:

adapter for connecting power to the base;
telephone cord with RJ type plugs;
a tube;
set of AAA Ni-MH batteries.

Depending on the model, there may be two tubes, therefore, there will be 4 batteries.

Connecting the base

The first step is to connect the adapter to the network and to the base. For the first start, switch the power switch to the On position on both devices. To search for a handset, press its call button with the corresponding icon. On Panasonic devices it is located on the front panel of the base.

Setting up a Panasonic radiotelephone

Now let's figure out how to set up a Panasonic radiotelephone. The principle of setting up phones from this brand is the same and is done using push-button dialing in accordance with the instructions. You can download it on the official website of the company itself.
For the first start after physically connecting the telephone, you must register the handset. To do this you need to follow these steps:

On the handset, after turning it on, you must press the “Menu” button.
Use the arrows to select “Handset Settings” and press “OK”.
Next, you need to select the “Handset registration” menu and press “OK”.
On the base unit, you must press the handset call button. It has a corresponding design and, as a rule, is located in the most visible place. It can also be used when the handset has been lost to find it. Only in this case there is no need to hold the button. To register the handset, you must press the button and hold it for 5 seconds.

Moreover, if the handsets are registered, they will start ringing. To disconnect the call, you must press this button again. Repeated manipulation can be performed only after 90 seconds.
At this time, the message “Base PIN” will appear on the handset. Accordingly, we introduce it. The default is “0000” and confirm the entry by pressing the “OK” button. After successful setup, the antenna indicator on the handset stops blinking and starts to stay lit.
If for some reason the handset is not registered, you must remove the previously attached handset and repeat the process again.
To do this you need:

click the “OK” button;
go to the database settings and confirm the selection “OK”;
In the current window, enter the code “335” and when you click on the “OK” button, you will be taken to the menu for selecting registered handsets. Use the arrows to select the one you need and click “Yes”.
When changing your PIN code, be sure to save it on a physical medium, otherwise you will have to contact a specialized service.
Configure your phone settings
After the initial startup and registration of the handset, the phone must be configured for comfortable operation. These settings include selecting the menu language, setting the date and time. You can also select the dialing mode if necessary. The pulse mode is installed from the manufacturer's factory, which corresponds to modern telephone lines.
Selecting menu language

Setting the date and time
To select a language, click on the “OK” button in the menu and find the “Menu language” sub-item. We confirm the choice with the “OK” button and get to the list of all supported languages. In it, use the up and down arrows to find the required one and again press the menu selection button. On some phones, you must press the end call button to confirm the action and exit the menu.

A radiotelephone is a telephone whose signal is transmitted via radio waves, and not through wires, like a regular wired telephone.

Complete set of radiotelephones

The radiotelephone kit includes a terminal (telephone base) and a handset. Moreover, the number of tubes in a set may vary. Thanks to certain functions of such a phone, it is possible, if necessary, to establish communication both with the telephone network and between handsets. Installing a radiotelephone in an apartment or office is not particularly difficult. You can do this yourself, without resorting to the services of a professional. The place where it will be is very important. In order for the telephone to be installed correctly and the communication in the room to be of high quality, you need to follow certain rules.

Do not install the radiotelephone in places with high humidity. The device should not be exposed to direct sunlight.

If there are several radiotelephones installed in a room, then their bases should be spaced at a distance of more than two meters. This distance is necessary for effective signal transmission between the handset and the base.

Station installation rules

It is not recommended to install the telephone in close proximity to household appliances ( washing machine, microwave oven, refrigerator) or other sources electromagnetic radiation, which introduce interference into the signal. One such source may be an electrical cable running near the installation site. To provide normal operation Do not install heat emitters near your phone. It is unacceptable to have iron objects near the terminal. They can also interfere with normal operation.

Before turning on the phone, be sure to charge it properly battery. Charging must be carried out strictly according to the manufacturer's recommendations. By doing this, we will increase the operating time of the phone without recharging and extend the battery life. If you need to remove the battery from the handset or disconnect the base from the power supply, you must set a security code. This is necessary in order to restore the connection between the base and the handset after turning on the device again. The code is programmed using the “page“ key.

Since the connectors for connecting the power supply to the network and the connectors for connecting the radiotelephone to the telephone network differ in design from the standard ones, you will need to purchase the necessary adapters.

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

To connect the device to the switching network, you need a low-current node, the installation of which can be done by yourself. We will tell you in detail how to connect a telephone socket without calling a technician. There is absolutely nothing complicated in the schemes and methods, and the useful information we offer, as well as photos and videos, will help you understand the issue.

Design features of a telephone socket

The designs of landline telephones are modified and improved every year. And modern devices are significantly superior to their predecessors, standing out favorably with their high reliability and ease of use.

To ensure uninterrupted operation of the device, two conditions are necessary:

Availability of an active communication line from the PBX.
Possibility of electrical connection of a stationary device to this line.

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

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

A telephone jack is required to create a durable but quick-connect connection between a landline telephone and landline telephone lines.

The socket for connecting a telephone can be installed separately or in the format of a block of power and switching sockets

To this day, in old buildings and budgetary organizations that are more than 15-20 years old, lines with Soviet standard sockets are found. Outdated type of connection RTShK-4

Now low-current networks are equipped with completely different connectors that correspond to the RJ group of standards

To facilitate the installation and connection of the socket, the inside of the device is equipped with marks and color codes that help to correctly connect the contacts

Series of sockets with RJ connector (9; 11; 14; 25) have a similar design and dimensions, but are equipped with different plastic plugs. The shape and dimensions of the steps exclude connecting a telephone to an RJ45 socket

To connect two structurally different phone models, for example, an outdated wired and radio modification, combined options are used with the ability to install an old plug and RJ plug

In a combination socket, the RJ connector is located on the side, and the contact holes for connecting the plug are on the front part

Combination socket location

Despite the differences in design and connection methods, any telephone socket traditionally includes three main elements:

Frame– made of dielectric material (ceramics or plastic).
Contacts– spring-loaded brass elements that ensure reliable passage of currents through the electrical circuit.
Terminals– adapters necessary for connecting wires.

The electrical contact sockets of the stationary socket are recessed into the housing. This solution allows you to protect the device from accidental short circuits.

There are single and multi-connector models on sale. The first ones are designed to connect one device, the second ones allow you to switch several devices at once.

Connecting the telephone to create a landline connection is carried out through the socket supplied with the plug

Old and modern device standards

As equipment has improved, the way phones connect to the communications network has undergone a number of changes. In the first models of telephones, connection to the communication line was carried out without the use of sockets at all. To create a closed current loop, the wires were simply twisted together or connected by any other available means.

In the 80s of the last century, connections between telephone exchange lines were made using two-core copper wires. And to ensure a quick-disconnect connection to the telephone, sockets and plugs of the RTShK-4 standard were used. This abbreviation stands for "four pin telephone socket."

The cases of such devices are equipped with a protective key - a plastic connection that allows you to prevent incorrect installation plugs into socket

The RTShK-4 design includes a key and two pairs of contacts. The first pair ensures the phone operates in normal mode, the second pair allows you to connect an additional line, provided that both devices are on the same phone number.

As a result of the widespread dissemination of microprocessor technologies, Registered Jack equipment marked “RJ” began to be actively used to replace obsolete models of the RTShK-4 standard. It complies with the international standard IEC 60884-1 and 60669-1.

Modern standardized equipment for low-current circuits allows you to connect up to four pairs of working contacts to the circuit

Connection of modern landline telephone models for use at the household level is carried out through sockets equipped with one pair of contacts. The housings of such devices are mounted in the cavity of a plastic module and are marked with RJ-11 symbols. Between the two contacts, which are compact metal plugs, the cores of the supply wire are buried.

In the central part of the plastic module, called the manipulator, there are brass contacts through which the electrical network between the phone and the PBX

To connect two devices to separate lines and create office mini-PBXs, RJ-12 and RJ-14 standard devices are used. Universal four-wire connectors are suitable for most models of telephone equipment.

To connect several devices at once, you just need to assemble the sockets sequentially into blocks, while observing the diagram: the first line is connected to contacts No. 2 and No. 3, and the second - to No. 1 and No. 4. Devices of this series are mostly used to create mini-PBXs when arranging office premises.

Such modules are mainly used when it is necessary to connect a vintage exclusive old telephone with new telephone wiring

Models with a combined RTShK-4 and RJ-11 connector are no less in demand. Installing adapters allows you to connect plugs of both old and new standards with lines equipped with modern technologies.

The main difference between RJ-25 standard devices is three pairs of working contacts. For this reason, the connection of such equipment can only be carried out by a qualified specialist who is well versed in telephony and electrical issues.

The RJ-45 connector has four pairs of pins, but only the two pins located closer to the center are used to create an electrical circuit

When connecting faxes, modems, computer systems and other complex communication devices also use the RJ-45 standard. When connecting RJ-45 devices, the main attention is paid to the matching of the plastic keys.

Despite the design differences between the old and new standards, the device plugs have similar connectors and dimensions. The device is connected to the network only through two contacts. Only in modern models only the middle contacts are used.

Installation diagrams and connection methods

Connecting a telephone socket is much simpler than its electrical counterpart. But a process that involves working with, albeit low, but still voltage, requires accuracy and caution.

The connection diagram for a telephone socket is quite simple and involves connecting the two ends of the telephone wire to the corresponding contacts in the socket

When installing a telephone socket, you can use one of two installation methods:

open - involves installation in an overhead manner;
closed - in which the telephone line is hidden inside the wall.

When choosing a laying method, they are guided by the design of the walls, the service conditions of the communication line and the pretentiousness of the design of the room itself. Surface-mounted sockets do not look very aesthetically pleasing, but they are ideal for speed of maintenance: in a matter of minutes they can be removed from the support and the integrity of the contacts can be assessed.

The open method can be carried out without mounting it on the wall at all, by placing the device on the floor, and hiding the cable leading to it under the baseboard

To protect exposed wires from mechanical damage, decorative plastic cable channels are used. They are found on sale in the form of wall structures and floor skirting boards. It is convenient to monitor the condition of the wire in them through one- or two-sided snap panels.

For closed installation, KSPV cable is most often used. The single core of this cable is made of copper wire, and the outer sheath is made of polyethylene, painted white.

The telephone line is also laid using the TRP distribution cable. It has a dividing base. The core of this single-pair wire is also made of copper and insulated with polyethylene.

For ease of use and harmonious combination with the design, telephone sockets are not installed separately in the wall, but are included in the socket block

To decorate the connection points and make them less noticeable to prying eyes, the devices are placed behind TV screens and monitors, and are also built behind the façade of wall-mounted furniture.

A separate line should be highlighted for sockets built into the baseboard. The main thing is to choose models whose front panel fits tightly to the surface of the baseboard. Otherwise, over time, it will begin to move away from the base, exposing unsightly seams.

How to connect a telephone socket

When installing a telephone socket, it should be taken into account that the voltage for low-current communication devices does not exceed 60 Volts. But even reduced voltage can still create a current, causing discomfort to a person. At the moment when a call occurs over the telephone line, the voltage completely rises to 110-120 Volts. And it can cause serious pain upon contact. It drops to a value of 12 Volts only after removing the handset.

In order to comply with safety regulations, all work on connecting an existing telephone circuit is recommended to be carried out wearing protective rubberized gloves.

The principle of placement and method of installing telephone sockets is practically no different from the technology for installing electrical sockets. Since today the most common devices are those that have the J-11 and J-12 standards, we will consider the intricacies of connecting a telephone jack using their example.

Stage #1: Preparatory work

The first thing you need to do is study internal communication patterns. They are included with the product instructions.

There should be no problems when connecting the J-11 and J-12 standards: you just need to connect the wires of the appropriate polarity. The main thing is that in the plug suitable for the device, the wires are brought out in mirror image socket contacts.

If you unknowingly purchased and plan to install the J-25 standard, the design of which involves 6 contacts, use only the 3rd and 4th contacts for connection.

According to the standard, a wire of a certain color is connected to each contact; this solution increases ease of maintenance and facilitates repairs. The connection order is indicated in the diagram by numbers

When planning to use an old standard device, you should worry about purchasing a universal socket in advance. It is equipped with a four-pin connector and connector. In addition to the socket itself, it is also necessary to prepare a two-core wire with a cross-section of 0.3-0.5 mm.

The following tools need to be prepared for the work:

building level;
cross knife;
voltmeter;
screwdriver;
wire cutters;
graphite pencil;
protective gloves;
Double-sided tape;
hammer drill (if installing a new point).

When choosing a screwdriver, you are guided by the type of surface and dimensions of the screws used for fastening. To minimize the chance of defeat electric shock, it is better to perform all manipulations with a screwdriver, the handle of which has insulation.

Having marked the location of the connection point, use building level correct the horizontal and vertical position of its position

To connect a hidden type socket, you must first make a hole in the wall for its installation - a socket box. This can be done using a hammer drill equipped with a special crown with a diameter of 60-70 mm. In the absence of one, the work can be done with an ordinary hammer and chisel. But manual labor will take much more time and effort. Then, to the hole made, it is necessary to drill a channel for laying the telephone cable.

Stage #2: Stripping the ends of the cores

Before you start melting the wires, you need to strip the ends of the wires, removing the outer layer. Just expose the outermost 4 cm of the wire.

When stripping a telephone cable, remember that it is very vulnerable to damage. And broken wires will only lead to equipment malfunction. Since it is not always possible to carry out the cutting accurately the first time, experienced craftsmen recommend that when laying the cable, make some allowance for its length. The excess wire can then be hidden under the cover of the device.

Removing the protective insulation from the ends of the cable should be done extremely carefully, using a cross-cutting knife, a sharp blade or side cutters.

The technician’s task is to strip the ends of the wires from the braid so that when exposed they are intact and free of any defects.

Step #3: Connecting the outlet wires

Stripped wires with separated cores are connected to the connectors of the box itself, focusing on the markings indicated on the front panel of the indoor unit. With a closed installation method, for ease of connection, the wires are made to protrude beyond the wall plane by 50-80 mm.

To maintain polarity when connecting wires, follow the rule: red insulation on the line with the “-” sign, and green braiding on the “+”

If the rules regarding polarity are not followed, there is a high risk that the telephone will malfunction from time to time during operation.

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

The supplied cable cores are applied to the clamp and tightened tightly with special screws, ensuring reliable fixation. The shape of the grooves to which the cores are attached facilitates the installation process. There is no need to wrap the joints with electrical tape.

When connecting devices whose design is equipped with four fork-shaped contacts, only the two central contacts are used

When performing open mounting, at the final stage all that remains is to close the housing cover using the latch and secure it with screws. The finished socket is attached to the wall or floor, “planting” it with double-sided tape.

With a closed installation method, making sure that the wires are not intertwined in the socket box, according to the markings applied, the indoor unit is mounted into the wall. Having given the block the desired position, the structure is fixed using expansion screws and self-tapping screws.

At the final stage, all that remains is to eliminate the gaps between the socket box and the wall, covering it with gypsum mortar, and also seal the channels with the laid telephone cable.

After the plaster has acquired the desired strength, the protective edging is installed in place and the front panel is attached. In modern devices, the protective edging snaps onto indoor unit, and the front panel is secured by screwing in screws.

If you need to connect a multi-socket outlet that allows you to install several telephone sets, you must adhere to the same technology as when installing the classic version of the device. The only difference in the process is the increase in the number of conductors requiring connection.
