In this case, the cost of creating communication tools is significantly reduced, there is no need to use additional mating devices and channel transfer devices from one communication device to another, and this helps to increase the speed of deployment of communication tools, accelerate channel setup and, accordingly, reduce the time of establishing new and restoring broken connections .

At the reception, digital signals from the VHF channel output of the radio station 19, multi-channel radio station 22, radio relay stations 25 or 28, as well as pulse channel forming equipment 18 or wire communication equipment 30 through blocks 13, or 14, 15, or 16, blocks 11 and 8 are transmitted to the input of the automatic speech-converting device of the ARPU block 12, which converts them into analog signals and passes through the cord set of the block 43 of service devices and the block 42 of the switching field to the input of the subscriber set of the block 41 of the subscriber sets comrade, and then these signals through block 4 of the subscriber cross, block 3 input lines and subscriber line 1 are received at the input of the telephone set of the subscriber.

The encryption mode of information transmitted over long-distance communication channels is carried out by including the first 13 and second 14 individual encoders, the first 15 and second 16 group encoders in the compiled negotiation path.

When using the first 13 or second 14 individual encoders, its inclusion in the tonal frequency channel, formed, for example, by wire communication equipment 30 or radio relay station 25 with frequency division of channels, is carried out between the block 44 channel sets of the telephone exchange 6 and the PM channel through electronic cross 8.

In the transmission, the group signal from the output of the equipment 33 for data transmission is fed to the input of the grouping unit 24. From the output of the grouping unit 24, the group signal, after matching the levels, is transmitted through the transmission converter to the exciter of the transceiver of the relay station 25, and after amplification, the modulated high-frequency signal from the output of the transceiver of the relay station 25 enters the antenna 26, which radiates a high-frequency signal to the air.

Radio access of subscribers from a mobile multi-channel communication station to the mobile radio communication network is carried out using VHF radio station 19 with antenna 20 and multi-channel radio station 22 with antenna 23. Moreover, the paths for transmitting information and communicating are organized according to a known method implemented in communication systems of the MRT 1327 standard. The connection process includes the following steps. Exit to the radio communication network and call the subscribers of the mobile radio communication system by automatically dialing the number on the control panels of the VHF radio station 19 and multichannel radio station 22, as well as by dialing the number on the communication panel of unit 7 of the workstation connected to the radio channels through the telephone exchange 6, electronic cross 8 digital channels and electronic cross 11 analog channels.

The automatic determination of the coordinates of a mobile multichannel communication station is carried out using navigation equipment 40, which automatically determines the geographic and rectangular coordinates of a moving object (a mobile station mounted in a moving object on the chassis of a cross-country vehicle), its speed and other movement elements in real time and implements input of the received data into the ARMO 10.

In the proposed mobile multi-channel communication station, the collection, synthesis, display and documentation of information on the status of communication, channels and equipment is carried out using ARMO 10. Moreover, data on the state of the equipment of the telephone exchange 6, electronic cross-link 8 digital channels, electronic cross-link 11 analog channels, equipment 33 data transmissions and channels formed by it, ATT 37 and the channels included therein, are transmitted to a personal computer 55 ARMO 10 directly from the listed equipment, and data on the status of the subscriber x lines 1, connecting lines 2 and equipment (block 3 input lines, block 4 subscriber cross, block 5 differential systems and block ARPU 12), related to the telephone exchange 6, are sent to ARMO 10 through the telephone exchange 6. Status data of individual 13 , 14 and group 15, 16 encoders, UPS ТЧ 17, pulse channel forming equipment 18, VHF radio station 19 and its channels, time division multiplexing unit 21, multi-channel radio station 22 and its channels, grouping unit 24, radio relay station 25 with frequency division of channels and its to analogs, apparatuses 27 for consolidation of group paths, digital 28 for radio relay station and its channels, apparatuses 30 for wired communication and its channels are supplied to ARMO 10, respectively, through electronic cross 8 digital channels and electronic cross 11 analog channels. The data received at ARMO 10 are generalized and stored in the RAM 60 of the personal computer 55. If necessary, the received data can be output to a video monitor 73 and printed using a printer 75.

In case of violation of established connections for various reasons, including due to failure of equipment or communication channels, emergency light and acoustic alarm is turned on in ARMO 10, which attracts the operator’s attention, and he displays data on the state of technical equipment on the screen of the video monitor and channel determines the malfunction of the equipment or communication channel.

The technical efficiency of the proposed mobile multichannel communication station is to expand the functionality, increase the efficiency of establishing connections and the scope of communication services provided to consumers, achieved through the formation of analog and digital channels by means of radio, radio relay and wire communication, combined in one object, to ensure transmission over educated channels telephone, telegraph and facsimile communications, exchange of data and documentary information between local subscribers networks on subscriber and trunk lines, with remote subscribers on tone frequency channels and digital communication channels, providing cryptographic protection of the transmitted information from interception and the introduction of false information into communication channels.

Improving the efficiency of establishing communications is achieved through the introduction of an electronic cross of 8 digital channels, an electronic cross of 11 analog channels and the direct inclusion in the cross of communication channels formed by means of channelization (radio stations 19 and 22, radio relay stations 25 and 28, equipment 30 wire communication), automatic cross-check channels of their condition, combining crosses and channel forming means in one object, approaching communication channels to consumers included in telephone exchange 6, which Allowed to exclude additional time costs for the transfer of communication channels from channelization facilities to consumers. Calculations and operating experience of facilities similar to the proposed mobile station showed that it takes about five minutes to transfer one communication channel from channelization facilities to the telephone exchange (via cross channels) through deployed multi-wire cable lines, and twenty channels to transfer to a small telephone exchange it takes about 100 minutes, that is, we get a significant gain in the transmission time of channels, which is an integral part of the time for establishing new and restoring broken connections, due to t exceptions to this component.

The provision of access from the telephone exchange 6 to the channels of the mobile radio communication network using VHF radio station 19 and multichannel radio station 22, the possibility of maintaining telephone and data exchanges through these radio channels contributed to the expansion of the scope of communication services provided to consumers (subscribers).

In addition, the station, due to the introduction of the second individual and second group encoders, provides additional protection against interception of telephone messages, document information and data transmitted via communication channels, which expands the scope of the possible use of the proposed mobile multi-channel communication station on special purpose communication networks.
