Long-distance connection Internet provider. A distant sound. By ceasing to process the input connection from the place, or the internal and output connection, you begin to work

“Oselya is far away” Literature “Oselya is far away” EXPENSION AT THE HOUR AT THE Memorial Apartment O.S. Pushkin on Arbat held a thematic evening-zustrich, the name given to Pushkin’s rows: “Far away and clean feet.” This is how he sings about

Between two points that are located at a distance (practically not interconnected) there is one view of one another. The term “long-distance communication” originates from the technology of transmitting electrical signals over wire lines.

In the old order, international and international calls were made by dialing the number 8 (at telephone exchanges with automatic interconnections, for most of them), and dialing through the Rostelecom operator. For the new procedure, it is not enough to dial “8”; you must select the operator through which the call (two-digit number) will be sent, and then the number. In addition, you can switch to one of the operators on a permanent basis (mode), in which case the order of dialing the number is old simply through “8”, and the operator is always on call all the time. In this mode, you can make calls through other operators by simply selecting code 15 after “8”, and then continuing with the new schemes.

In a number of regions, subscribers can select the Pre-Select mode without visiting the company’s office by calling a special automatic number. This is possible in the companies MGTS (Moscow), Dalzvyazok (all subjects of the Far Eastern Federal District), Uralsvyazinform (all subjects of the Urals Federal District), Bashinformsvyazok (Bashkortostan), Tattelecom (Tatarstan).

Alternative operators are running a campaign to call subscribers, encouraging them to switch to their services right during the call - for which they can complete their selection through an automatic number. Also, any subscriber can make long-distance calls by immediately selecting an operator for that call (Hot-Choice mode).

In mode, if a subscriber chooses to dial one operator and is deprived of his services, the dialing order is preserved:

• 8-beep-АВС-ххх – when the phone rings, (de: АВС – location code, ххх – subscriber number)
• 8-beep-10-country code-xxx - for international calls (de: xxx - location code and subscriber number)

In mode Hot-Choice The subscriber selects an operator using a skin call:

• 8-beep-mizhmyskogo operator code-ABC-xxx – when you ring (de: АВС – location code, ххх – subscriber number)
• 8-beep-international operator code-country code-xxx - for international calls (de: xxx - location code and subscriber number)

• 8-beep-15-universal operator code-8-АВС-ххх – with a ringing call (de: АВС – location code, ххх – subscriber number)
• 8-beep-15-universal operator code-810-country code-xxx - for international calls (de: xxx - location code and subscriber number)

When calling mobile phones from landlines with federal numbers, the same rules apply.

• 8-beep-international operator code-xxx-xxxxxxx (xxx-xxxxxxx - mobile phone)

• 8-beep-15-universal operator code-xxx-xxxxxxx (xxx-xxxxxxx - mobile phone)

Distant sound- telephone-telegraph connections with cable and radio relay lines between two points that are located at a distance (practically not interconnected) one way at a time. The term “long-distance communication” originates from the technology of transmitting electrical signals over wire lines.

Also, any subscriber can make long-distance calls by immediately selecting an operator for that call (Hot-Choice mode).

In mode Pre-Select, if a subscriber chooses to use one operator and is deprived of his services, the dialing order is preserved:

• 8-beep-АВС-ххх – when the phone rings, (de: АВС – location code, ххх – subscriber number)
• 8-beep-10-country code-xxx - for international calls (de: xxx - location code and subscriber number)

Further communication is the transmission of telephone and other signals to a large area. There are links between channels that connect stations (units) together. A communication channel is a set of technical line and station devices that can transmit changes electric strum telephone, telegraph or other signal.
The telephone channel is organized by the tone frequency channel of the primary EACC network with a slight bandwidth of 300 to 3400 Hz. With the physical lancinar, the communication range is determined by the amount of attenuation of the signal. Since the intensity of the signal at the output of the microphone of the transmitting telephone is approximately 1 mW, and the telephone of a suitable device will provide sufficient sensitivity at a pressure of 0.001 mW, then when the telephones are constantly turned on in the line The signal may change no more than 1000 times. Range of connection when setting:
on a wind tunnel with copper wires with a diameter of 3-4 mm - 300-500 km;
on a wind tunnel with steel wires with a diameter of 4-5 mm - 70-90 km;
on a cable line, with middle cores with a diameter of 1-1.2 mm - 20-30 km.
The communication range can be increased by changing the extinction (for example, by increasing the diameter of the wires), by increasing the level of transmission or reception (the inclusion of boosters). The boosters that boost tonal frequencies are called telephone boosters. To increase the range of the connection in the ring, turn on the interim boosters through the singing parts. A plot of lancet, spread between two vessels, between the transmission and the reinforcement, or between the reception and the reinforcement, is called a reinforcement plot. The loss of the cutaneous strength is compensated by the strengthening of the thyroid perineal strength.
When calling the same phone telephone set In order to transmit and then receive information, the transmission of information in both directions requires the creation of two independent one-way channels. Since boosters only boost currents in one direction of transmission, they are connected to a double telephone station using a differential DS system. The two-way telephone channel, which consists of two one-way channels, is shown in Fig. 66. Signal transmission in different directions takes place behind two different two-wire physical lances. Such a telephone channel is called a channel of a single-layer wire system. The name “single-channel” means that transmission in both directions is affected by streams in the same mix of frequencies.
A two-way telephone call can be organized using the same two-wire physical network. For this purpose, it is necessary to install two differential systems and two boosters, which are called duplex boosters, at the skin pressure point. Such a channel is called a channel of the single-layer double-wire system. Differential systems suppress the flow the call of the bell In duplex boosters, there is a constant balance between the supports of the balance circuits and the input supports of the supporting sections of the lancer. However, it is not possible to completely suppress the striae of the ligament, some of them pass from one section of the lancin to another, forcing them under strength. As the sumar stream of the gateway link will reach the great, create the mind of self-awakening of any kind of duplex booster. To avoid this, I will see the number of duplex boosters that are sequentially switched on at the lances, there is no need to overextend the five or six that separate the long-range connection. Therefore, for the connection on the large surface, four conductive channels are stagnated, the fragments of only one lance of the gate connection (through the differential systems of the end reinforcements) are removed, regardless of the number of intermediate forces Yuvachiv included in the channel. With only a few wired channels, a secondary station is needed to organize four darts instead of two.
