In the device 9 digital interfacing provides decompression of digital streams, the allocation of digital channels, their switching and transit. Dedicated digital channels from the device 9 digital pairings are transmitted to the block 8 switching channels and modes, where they are switched to the introductory shield 7.

The Ethernet channels from the output of the digital interface device 9 are transmitted to the first 23 and second 24 Ethernet switches and then, in accordance with the IP addresses, are transmitted to the introductory shield 7 or are used to organize the transit channels.

In the external compaction mode of the E1 stream, the signals allocated in the radio modem unit are transmitted directly to the output of the first 11 (second 14) monoblock transceiver of the DAC range, and then they are fed to the introductory shield 7 through the switching unit 8.

Information from the telecontrol-remote signaling channel (TU-TS) enters the cell of the monitoring and control module (MKU), which is part of the monoblock transceivers of the DTS and microwave range.

The service communication channel (KCC) with the corresponding levels of reception and transmission from the digital interface device 9 enters the block 16 external service lines and then through the first 19 or second 21 operator communication units (BSO) switches to the corresponding MTT 20 or 22.

Switching subscriber channels is carried out on block 8 switching channels and modes, depending on the mode of operation.

Subscriber channels can be transmitted in the STM-1 stream via an optical cable. The formation of streams produced in the device 9 digital interface.

For quality control of subscriber channels, an external analyzer of telecommunication networks (Bercut-MMT device), a digital path parameters analyzer (Bercut-SDH device) and a telecommunications interface signal analyzer (AIST) are used, connected to digital channels with disconnections and to PM channels without disconnection in the radio relay line.

The hardware and equipment control is provided from the control computer of the first 17 or second 18 automated operator’s workplace using a computer or a touch screen monitor via an Ethernet interface.

The monoblock of transceivers can also be controlled from the front panel of the monitoring and control module (MKU), which is part of the monoblock transceivers of the DAC and microwave range.

Antenna alignment in the vertical and horizontal planes is performed by controlling rotary support devices using the ARMO control computer via the RS-485 interface.

In the transmission mode, analog information with the appropriate level comes from hardware communications via the PM channels and via SL 25 through the introductory shield 7 to the channel switching unit 8, where the PM channels are switched and information is transmitted to the digital interface device 9. Here from the MTT 20, connected to the first block 19 of the operator’s communication, the overhead channel (CCN) is received.

Formed from the channels of PM and KCC group signal from the output of the device 9 digital interface enters the transmitting path of the first monoblock 11 transceiver range DTSV (direction 1) or the second monoblock 14 transceiver range DTSV (direction 2) depending on the position of the switch "DIRECTION" on block 8 switching channels and modes. Next, the group signal in the composition of the high-frequency (RF) signal through the first triplexer 10 and the introductory shield 7 is transmitted to the first 1 or second 4 antenna of the VHF range.

Mode terminal digital on the main digital channel (BCC).

The terminal end mode via the bcc channel is intended to ensure operation at a speed of 64 kbps in digital mode in the DZV range. Depending on the communication scheme, the mode is organized in one of the communication directions or simultaneously in both. In this mode, digital information on one of the channels of the BCC enters through the connector of the introductory shield 7 to the block 8 of switching channels and modes, which is used to switch the used channel of the BCC to the device 9 digital interface. The device 9 switches the used BCC channel to the first channel interval of the E1 stream, which in turn switches to the E1 channel of the E2 stream formed in the device 9. The formed E2 stream flows through the connector of the first monoblock 11 (or the second monoblock 14) to the input of the radio modem, in which there is a selection of BCC from the stream E2. From the BCC, KCC and TU-TS channels a group signal is formed with a transmission speed of 85 kbit / s, which enters the transmitting path of the radio modem, where it is modulated and transmitted as part of the RF signal through the first triplexer 10 (or the second triplexer 13) and the introductory shield 7 in the first 1 or second 4 antenna range of the CAT.

The received parabolic antenna 1 or 4 high-frequency signal from the correspondent enters through the introductory shield 7, the first triplexer 10 (or the second triplexer 13) into the receiving path of the first monoblock 11 (or the second 14 monoblock) transceiver of the DZV range, where it is amplified, transformed and demodulated. From the demodulated group signal with a speed of 85 kbps in the radio modem, the BCC and KCC channels are allocated. The dedicated BCC channel is inserted into the E1 channel intervals of the generated E2 stream, which from the output of the first monoblock 11 (or the second 14 monoblock) transceiver of the DTS band enters the digital interface device 9. In the device 9 digital pairing is the selection of BCC from the stream E2. Dedicated BCC from the output of the device 9 digital interface through the block 8 switching channels and modes is fed to the introductory shield 7 and then on the SL 26 is transmitted to the consumer.

The service communication channel (KCC) in the radio relay line is organized by the group digital signal of the first monoblock 11 of the transceiver range of the DCV signal by switching the signal in the block 16 external service lines to the corresponding microtelephone handset (MTT) 20 connected to the first operator communication unit 19 (BSO).

Service communication over the radio channel is organized in any of the four directions of radio-relay communication with the possibility of group and selective calling of subscribers of interacting hardware.

Operational switching of service channels is carried out by a block of 16 dedicated service lines. Block 16 allows the telecom operator to negotiate both over the service channels of radio equipment with the supply and reception of a tone call, and over the wired connecting lines with the supply and reception of a tone call, as well as with the supply and reception of an inductor call over service pairs and local communication lines.

The hardware provides for the negotiation, submission and reception of a call between the operator of the cab and the operator of the body using the console 29 communication driver.

The control and monitoring system for service communication of the hardware is remote and allows you to control its parameters using control computers of the first and second ARMOs.

The technical effect of the proposed mobile hardware multichannel radio relay communication is to expand the functionality of the organization of multichannel radio relay communication lines with the provision of transmission through the formed channels and paths of various types of information. At the same time, the efficiency of establishing communication, reliability of operation and stability of communication in the radio relay line is also improved by implementing an automated system for setting up transmission and reception paths, an automated monitoring system for the presence of communication in the working mode, and finding fault in the “CONTR.” Mode, as well as availability of an indication of the state of the equipment and equipment of the mobile equipment, both in the on-call reception mode and in the communication process.

The availability of constantly updated information on the state of hardware equipment allows determining the state of the communication line and direction (reception or transmission) of its failure in case of a radio link failure, timely eliminating malfunctions and thereby increasing the reliability of operation, which practically leads to maintaining stable (uninterrupted) communication by radio-relay communication lines.

In addition, the proposed mobile hardware also provides for the possibility of issuing aggregated data on the state of communications, transmission and reception routes of radio relay lines to an external control center, which are used to monitor the operation of a radio relay line and the ability to remotely control the operation of mobile hardware equipment.

The advantage of the proposed mobile hardware is also the fact that it provides duplex adaptive multichannel communication in the face of artificial and natural interference in two decimeter wavelengths, the construction of analog and digital communication networks with automated circuit switching and packets in four independent directions of communication, organization and management service calls via service lines, field service cables, local service lines, and VHF station communications.
