On Fig is a diagram of the electrical circuit protection device 6, where it is indicated:

F1 - arrester (R-94 AGSR 4333210.006TU);

L1, L2 - the first and second chokes (DM-1.2-30 + 5% V "N" TsKSN.671342.001TU)

VD1-VD6 - first to sixth voltage limiters (2C517G aA0.339.665TU)

X1, X3 - the first and second connectors (plug ONTs-BS-1-4 / 10-V1-1V brO.364.030TU).

The protection device 6 is implemented on a board located in the housing. A protection circuit consisting of a R-94 arrester, low-capacitance voltage limiters 2S517G and inductors DM-1.2-30 ± 5% -V is placed on the board. The input-output of the second connector X3 is the input-output of the protection device 6. The output-input of the first connector X1 is the output-input of the protection device 6.

The protection device 6 is intended to protect the equipment of wire communication lines (one two-wire line) from impulse voltages and currents arising in wire lines under external electromagnetic influences of artificial and natural origin with a maximum level of induced impulse voltages relative to the housing - not more than 40 kV (with a front duration 5 μs), currents - not more than 5 kA (duration 20 μs), in the "core-core" circuit, loaded on the wave impedance of the line Z _l - no more than 2.5 kV.

The attenuation of the working signal by the protection device 6 in the frequency range from 0.3 to 3.4 kHz at a load of 150 Ohms is not more than 1 dB. The DC voltage limitation level of protection device 6 is from 64.2 V to 86.9 V.

The surge voltage is limited by the arrester F1 (first stage of protection) and semiconductor limiters VD1 ÷ VD6 (second stage of protection). Inductors L1 and L2 provide isolation between the first and second stage of protection.

Upon receipt of an overvoltage wave at the input of the block, breakdown of the discharge gaps of the spark gap F1 occurs, as a result of which the resistance of the spark gap varies from tens of MΩ to fractions of Ohm, and the voltage drops to ~ 40-50 V.

Due to the asymmetry of the line, as well as to a certain difference in the characteristics of the discharge gaps, their operation does not occur simultaneously, and due to this, pulsed voltages occur in the core-core and core-casing circuits, the limitation of which is allowed on the levels acceptable for the equipment protection level - VD1 ÷ VD6.

The proposed device operates as follows.

The subscriber complex is designed to work in facilities and is an amplification-switching device that provides all the subscribers of the facility with internal communication and each of the subscribers has access to external communication facilities: radio communications equipment (SIRS), intra-complex communications equipment (VKS), and an external telephone set. At the same time, circular and selective communication with external subscribers is carried out. In addition, the device provides the broadcast of any signals received by the subscriber from the radio station to the loudspeaker 5.

- chest switch modules 1.1.2-1.5.2 - for connecting electro-acoustic devices (headsets, microphones, etc.) to the switch module 3 and controlling the choice of transmit-receive modes when working with external communications, as well as selecting the “forced” mode circular".

The subscriber complex provides the following communication modes:

- internal two-way telephone communication between subscribers with listening to their own speech;

- internal circular communication with listening to your own speech with the switching of subscribers to the “internal communication” mode regardless of the operating modes they selected previously (“forced circular”) and automatic return to the selected communication modes after the “forced circular” mode ends;

- external circular communication using a radio station or VKS;

- external address communication using a radio station or VKS;

- external communication using TLF;

- receiving signals from equipment for the transmission of service messages through the first and second inputs of the device;

- access to external communications equipment - RSv, VKS (MKO) and TLF;

- sending a selective call to external subscribers via RSv and VKS;

- making a circular call to external subscribers via RSv and VKS;

- making a call to an outside party on the telephone;

- light indication of incoming calls by external means of communication with the ability to control the number of the caller;

- broadcasting of any signals listened by the subscriber via radio, VKS or TLF to loudspeaker 4;

- automatic registration (recording, storage, reading) of voice information (negotiations) with fixing the date and time when working with internal and external communications.

The signal from the electro-acoustic devices is fed to the input of the amplifier 1.1.2.1 of the chest switch module 1.1.2, which has an automatically adjustable gain in the frequency range from 300 to 3400 Hz. After that, the signal is converted into digital form and then goes to the switch module 3, where the devices are switched in such a way that the signal goes to one of the communication complexes (communication direction), or to the internal communication network. From the output of the amplifier 1.1.2.1, the signal is supplied to the codec 1.1.2.3, which converts the incoming analog signal into a digital form in the format of pulse-code modulation 64 (PCM64), then the signal is fed to the digital modem 1.1.2.4, which provides encoding, modulation and transmission speech signal in digital form over twisted pair to the module of the switch 3 through the corresponding first 2.1 or second 2.2 remotes.

In the module of the switch 3, the signal is fed to the corresponding digital modem from the first to the fifth 3.1-3.5, where the signal is demodulated and decoded. From the output of the modems from the first to the fifth 3.1-3.5, in a predetermined time window, a PCM 64 signal enters the second signal bus of the module of the switch 3. Under the control of the controller 3.13, the switch 3.12 commutes the signals from the breast switch modules from the first to the fifth 1.1. 2-1.5.2 to the time windows corresponding to the communication directions selected by the subscribers. From the switch module 3, through the corresponding first or second panels 2.1, 2.2, or directly, the signal is fed to the outputs-inputs of the chest switch modules from the first to the fifth 1.1.2-1.5.2. The signal received at the output-input of the subscriber kit 1.1 is fed to the output-input of the modem 1.1.2.4, which provides demodulation and decoding of the signal. From the digital modem 1.1.2.4, a signal in PCM 64 format is fed to the codec 1.1.2.3, which provides the conversion of the digital signal into analog form. From the output of the codec 1.1.2.3, the signal is fed to the input of the amplifier 1.1.2.2, which provides signal amplification. From the output of the amplifier 1.1.2.2 MNP 1.1.2, the signal is supplied to the electro-acoustic device, which is part of the subscriber kit 1.1.

Switch 3.12 operates under the control of controller 3.13, and control is carried out on a parallel control bus. The module 3 of the switch transmits and receives digital information in PCM 64 format on the first and second signal buses.

In the intercom mode, the signals from the microphones of the corresponding subscribers enter the switch module 3, where, under the control of the controller 3.13, the signals coming from all subscribers and the signals coming to the switch module 3 are mixed from external devices of the first type (for example, from the GO-27 equipment ( warning device)) and the second type (for example, the on-board control system of the automation system (BU SA)). The mixed signal is fed to the inputs and outputs of the switch module 3 for all subscribers currently working on the internal network. Information from all communication directions is transmitted via the second signal bus in sequential form to the corresponding time windows. Each communication direction has a separate window. Under the control of the controller 3.13, the switch module 3 can send information from any time window of the incoming stream to any time window of the outgoing stream. Also, the switch module 3 provides parallel connection of several telephone channels in the mixing mode, allowing simultaneous exchange of voice information between multiple subscribers.

In the radio mode under the control of the controller 3.13, the subscriber signal is switched in the time window intended for operation with the PCv equipment. After that, the digital signal in code 3.17 is converted into analog form for transmission to RSv equipment. The speech signal from the PCv equipment is fed into the module of the switch 3 - on the codec 3.17. The received signal in the codec 3.17 is converted from an analog form to PCM 64 format. From the output of the codec 3.17, the signal is transmitted to the second signal bus of the switch module 3 in a predetermined time window.

In the mode of intracomplex communication (VKS) under the control of the controller 3.13, the subscriber signal is switched in a time window intended for operation with VKS equipment. After that, the digital signal in vocoders 3.29, 3.31 is converted into a compressed digital stream and transmitted through the interface module with the MCO 3.30 to the VKS equipment. The speech signal from the videoconferencing equipment enters the switch module 3 — the interface module with the MCO 3.30, from the output of which it goes to vocoders 3.29, 3.31. The speech signal in the first and second vocoders 3.29, 3.31 is converted from the compressed digital stream into a PCM 64 signal. From the output of the first and second vocoders 3.29, 3.31, the signal is transmitted to the second signal bus of the switch module 3 in a predetermined time window.

In the telephone communication mode under the control of the 3.13 controller, the subscriber signal is switched in the time window intended for working with the telephone line. After that, the digital signal in the codec 3.27 is converted into analog form and transmitted to US 6, from the output of which the signal is transmitted to the TLF. The speech signal from the TLF through the US 6 enters the module of the switch 3 - on the ULF 3.28, which carries out the amplification of the received signal. From the output of VLF 3.28, the amplified signal is fed to the input of the codec 3.27. In codec 3.27, the signal is converted from analog form to PCM 64 format and transmitted to the second signal bus of switch module 3 in a predetermined time window.

Buffers 3.10, 3.14, 3.16 are serial port (BPP) buffers of the RS232 type, buffer 3.15 is a RS485 type BPP.
