How to make a Skype Telegram radiotelephone extension cable with your own hands. Everyone who works with computers knows the Skype program very well. Working on Skype allows you to negotiate virtually for free and see your interlocutor on the other side of the world. Skype is also very convenient for local communications, when you need to conduct long discussions or consultations. In ordinary life, no additional communication equipment is required other than a microphone, speakers or headset. It is convenient to work with such a communication kit when negotiations are not long or you constantly need to access the computer. And when conducting lengthy negotiations on abstract topics, constant connection to the computer can tire and restrict freedom. To eliminate this inconvenience I decided to plug radiotelephone to computer. A study of the documentation for various types of radiotelephones showed that there should not be any difficulties connecting to a computer. From the telephone trash we managed to select a Panasonic KX-TCD700 entry-level DECT phone; the phones are reliable and can still be found in offices. This is a 900 MHz radiotelephone with a communication range of up to 70 meters and, most importantly, requires AA batteries for its power, and not special batteries. With the choice of the donor's radiotelephone, the question of how to make a radio extender for Skype with your own hands began to be resolved.

How to make a Skyphone with your own hands

1. Insert the batteries into the handset, connect the 220V adapter to the base and check the functionality of the radiotelephone when connected to a regular telephone network. The device must be working. The details of setting up the base tube are given in the operating manual.

2. Open the base. At first I felt uneasy at the sight of the tight installation. But studying the diagram and extensive marking of elements on the board made it possible to calculate and find connection points to the conversational node of the board. Connection points can be selected as guidelines when adapting to a computer and other phone models; in my opinion, any radiotelephone can be connected. It was necessary to find the transmission and reception signals going to the conversational node of the telephone line and route them to connect to the microphone input and line output of the computer. According to the scheme, these are RX-AF and TX-AF signals, respectively. To connect to the computer, test point TP82 and capacitor C62 were selected (control point TP96 is not marked on the board).

3. The connection cable was taken from the cheapest computer headset, this pleasantly speeded up the work. The ends of the cable conductors are cleaned and coated with solder.

4. To isolate galvanic connections along the signal circuits and limit the strength of the signals, the connection to the control points is made through two RC circuits. An RC circuit is a series connection of a 0.1uF capacitor and a 5.1kOhm resistor. Soldering locations are shown in the wiring diagram and photograph. Extension conductors are soldered to the control points. The capacitors are glued with hot glue, and the resistors are fixed in a volumetric way

5. The headset cable is passed through the hole in the RG-45 connector and soldered at the corresponding ends to the capacitors. The cable is secured in the connector with hot glue. The RX signal goes to the microphone input, the TX signal goes to the line output. Passing the cable through the connector simultaneously provided foolproof protection. I admit that if you simultaneously connect the phone to the telephone network, some troubles may occur, for example with the microphone input.

6. We assemble the base and connect the radiotelephone. The homemade radio extender based on the Panasonic KX-TCD700 phone worked immediately, it was only necessary to correctly adjust the strength of the signals using the computer settings. Tests showed the functionality of the device at a distance of 30 meters from the base (there was a comfortable sofa there 😉). Since it is not possible to establish a connection in the program from a phone connected to a computer, the connection is established in the usual way, and then you can pick up the handset by pressing the key and start a conversation.

Cord output

From the communication features it follows that the speech signal has become more compressed (features of a radiotelephone), but on the other end the interlocutors usually did not notice anything unusual, except for the incomprehensible empty space in front of the computer when the video link was turned on. Once the call is over, it's a good idea to go back to your computer and check for a disconnect.

To further improve the homemade device, you can consider the option of end-to-end control of computer speakers or headsets, which will turn off when removing the handset from the base or turning it on, but this will of course complicate the design.

At the request of readers, connection points for Panasonic KX-tcd410rum(rus)/KX-tcd412rum(rus)/kx-a141rum(rus)/kx-a142rum (rus) and KX-TC1245RUB ( , ) phones have been provided. Friends, do not forget to report the results of the rework, the site is working, thank you.

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.

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. 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 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.

MICROPHONE required

If your computer has a sound card and speakers (headphones) are connected, then this is the easiest way.

The cost of simple microphones is 50-100 rubles.
They are often made with a flexible leg and on a stand.

- If you listen through speakers, then there is no privacy of the conversation.

Method 2

Headset required

If the computer has a sound card, then you can connect headphones and a microphone made in a single design (the so-called “headset”) to it.
The cost of headsets ranges from 300 rubles and above.

The headset must be connected with one plug to the microphone jack, and the other to the headphone output on the sound card.

The connected microphone can be used to record podcasts.
+ Both hands are free.

- During a long conversation, if the headset is heavy, you may feel discomfort.

3 way

Homemade ADAPTER
for a regular (or radio) telephone working as a headset

If your computer has a sound card, then you can connect a homemade adapter to it, to which you can connect a regular telephone or cordless telephone as a headset.

The cost of a landline phone ranges from 350 rubles and above (you can use an old one with a round dialer). However, today finding an old unused phone is not a problem.

The cost of parts for the adapter is less than 50 rubles, not including the 9-12 volt power supply.

The adapter must be connected with one plug to the microphone jack, the other to the headphone output of the sound card (not to be confused with speaker output!).

The telephone conversation takes place in the usual “style”.
+ No one will hear the content of the conversation (relatives, neighbors).
- A 9-12 volt DC power supply is required. Since the current consumption is about 20 mA, the Krona battery will not last long (10-15 hours). Larger batteries should be used.
- The call and dialer will NOT work with this connection method. The phone is used only as a headset.

Note There are programs that allow you to dial subscriber numbers from a push-button telephone! But such programs cost several tens of dollars. It is better to spend this money on a SIP adapter, connect a push-button telephone to it, and receive/make calls when the computer is turned off (connection method No. 5).

4 way

USB phones

As a rule, USB phones already have a built-in sound card. And even if on the computer no sound card, this will not affect communication capabilities. If only the computer had a free USB socket.

Unfortunately, often such phones only work as a headset. That is, dialers do not always work (you have to dial with the mouse). SIP programs almost always work well in combination X-Lite and "driver" XLiteMate. When using these programs, the dialer buttons will also work.

Ring tones are ordinary audio files in a special program folder XLiteMate. You can replace the melodies with your own.

Structurally, such USB phones are made in three variants:
. In the form of mobile phones with a cord - cost from 300 rubles;
. In the form of landline phones - cost from 1500 rubles (for example, Skypemate USB-P4K);
. In the form of wireless radiotelephones - the price is above 2500 rubles.

The last two points are obviously better not to use. It is cheaper and more convenient to use a SIP adapter, connect a push-button telephone to it and receive/make calls when the computer is turned off (connection method No. 5).

USB handset phones are convenient for travel. They can be connected to a laptop. Where there is Internet, there is communication!
+ Radiotelephones do not have a cord (“base” is connected to USB).
+ Desktop devices are familiar in their use.
- When using any USB phone, the computer must be turned on with two special programs running: a SIP client and a “driver” (the latter program is usually included with the device).

This method is convenient for USB tubes connected to netbooks/laptops when traveling and using Wi-Fi in hotels and train stations.

SIP ADAPTER
for a regular (or radio) telephone

By connecting a small adapter to the Internet - to which, in turn, you need to connect a regular push-button telephone or cordless telephone - you can get a full-fledged IP telephone that receives and makes calls. In this case, you must remember to switch the phone to tone dialing mode.

The cost of adapters is from 800 rubles ( Linksys PAP2T on eBay.com with delivery) and above.

<= Адаптер Linksys PAP2T-NA

The telephone conversation takes place in the usual “style”
+ No one will hear the content of the conversation (relatives, neighbors);
+ Since the computer is not involved in communication, it can be turned off. Or there may be no computer at all;
- If the adapter does not have a built-in router, you must purchase a separate router with 4 ports. The computer will be plugged into one port, the adapter will be plugged into the other.

If the adapter has a built-in router, then the network cable is included in the adapter. The computer connects to the Internet via an adapter.

Using a SIP adapter to a regular push-button telephone (preferably a radiotelephone) is perhaps the most convenient and inexpensive option for connecting to full-fledged IP telephony without using a computer.

When purchasing an adapter, you should definitely pay attention to how many SIP accounts it supports. This will determine how many servers you can connect to at the same time. The one mentioned above is the cheapest Linksys PAP2T supports two accounts on different SIP servers. However, it also requires connecting two phones at once. Essentially, it contains two independent SIP adapters. You can receive calls on one phone (a cordless phone is convenient), and you can make calls from the other, a landline. Moreover, in this case, you can choose a less expensive cost for calls to certain destinations for outgoing calls. After all, all SIP servers have their own tariff plans.

6 way

SIP phones

By connecting your IP phone to the Internet, you can receive and make calls. The computer may be switched off or even absent.
Such SIP (and/or Skype) telephony devices are the most complete version of the development of IP telephony.

Some models allow you to connect to several SIP servers at once. When making calls, you can choose the most suitable server for a specific direction and reduce financial costs.

The cost of IP phones ranges from 2,300 rubles and above.

There are also phones with Wi-Fi handsets.

Phones with screens for video communication cost from 10,000 rubles. and higher.

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 of electromagnetic radiation that interfere with the signal. One such source may be an electrical cable running near the installation site. To ensure normal operation of the phone, do not install heat emitters nearby. 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 properly charge the 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 housings of such devices are equipped with a protective key - a plastic connection that helps prevent incorrect installation of the plug into the 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 an electrical network is created between the telephone and the telephone exchange

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, the RJ-45 standard is also used. 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 routed in a mirror image of the contacts of the socket.

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 likelihood of electric shock, it is better to perform all manipulations with a screwdriver whose handle is insulated.

Having outlined the installation location of the connection point, use a building level to 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.
