In the study of known technical solutions in the art, the totality of the features that distinguish the claimed station was not identified. The proposed solution is significantly different from the currently known technical solutions.

Thus, the claimed station operational telephone and documentary communications meets the criteria of the invention of "novelty." Comparison of the proposed solution with other technical solutions shows that the introduced blocks are widely known and additional creativity for their implementation is not required. However, when they are introduced in this connection with the rest of the circuit elements in the claimed station, the above blocks exhibit new properties, which leads to an expansion of the functionality for providing subscribers with various communication services, including the provision of voice and fax messages and high-speed documentary information (data, electronic mail) and video information with the required quality.

This allows us to conclude that the technical solution meets the criterion of "significant differences".

The claimed combination of elements and connections allows us to achieve our goal due to the original combination of instruments and devices used in telecommunication networks both in their direct and non-standard applications.

The claimed solution explicitly does not follow from the prior art and has an inventive step.

The inventive station can be implemented using existing apparatus and equipment, telecommunications and computer technology and is industrially applicable.

2) connection of manual and automatic telephone exchanges of similar purpose via medium-speed communication channels 1200 (2400) bit / s;

3) the deployment of a network that provides the connection of remote workstations for officials and the integration of types of information exchange (speech, data, e-mail) with cryptographic protection of the transmitted information;

4) deployment of a subscriber network using four-wire telephones;

5) deployment of a subscriber network using two-wire telephones;

6) deployment of a subscriber network using IP phones.

When routing in a circuit-switched network, telephone exchange 6 provides:

1) automatic selection of the direction of communication to the called station by the network number of the station (the first four digits of the number of the called subscriber);

2) search for outgoing communication up to two workarounds to the called station to reserve the main direction of communication in case of malfunction or busy;

3) automatic notification of network stations and the establishment of connections with mobile subscribers when they change the anchor stations.

When routing in a packet-switched network, the telephone exchange provides data flow routing in accordance with SIP V 2.0 routing protocols.

The inter-office interaction of the telephone exchange 6 through communication channels is carried out using alarm systems:

3) on the channels of a packet-switched network using SIP, SIP-T protocols.

For network subscribers, using four-wire SLTs, the telephone exchange provides the following service modes.

1. Auto service. In this connection is established by dialing a six-digit number by the subscriber. For the local network, abbreviated dialing is possible. Access to manual service is carried out by dialing a number of the operator of manual service of the station.

2. Semi-automatic service. For the local network, reduced dialing is possible. Manual service is accessed by picking up the handset from the telephone with a long absence of dialing or by dialing the number of the manual service operator.

3. Manual maintenance. In this case, the establishment of connections is carried out using the manual operator. Manual maintenance is performed by picking up the handset from the telephone.

The control device 40 of the telephone exchange 6 is designed to provide control of the processes of establishing a connection between subscribers, selecting a line and an operating mode along it, bringing station elements to an initial state at the end of negotiations. The device 40, in the process of establishing a connection, identifies the caller, issues commands to switch the caller line through the switching field of unit 4 to service devices, and from the received address information, it determines the way to establish the connection and issues executive commands for making the connection in the switching field of block 4.

The control unit 40 of the telephone exchange 6 is designed to control the processes of the station’s functioning, including the generation, conversion, transmission and reception of control signals, the distribution of control signals among various functional units, determining the status of service devices, linear sets and switching field devices, determining rational ways to establish a connection and the inclusion of switching points in the switching field, the diagnosis and prediction of the operation of units and stations in elom. The program of the station and the interaction of the elements of the device determines the automated PMA 21.

As the control device 40, a single-board computer, for example, a Micromax-type computer, can be used.

Telephone exchange 6 provides the following types of connections:

1) internal connections on subscriber communication lines (subscribers of the internal or local communication network);

2) outgoing and incoming connections on connecting lines from other stations;

3) outgoing, incoming and transit connections via long-distance communication channels;

4) encryption mode of information transmitted over long-distance channels.

The general procedure for establishing a connection is divided into two stages:

at the first stage, a call is received from a subscriber set or a set of trunk line, finding and connecting to them a control device for receiving information;

at the second stage, the nature of the connection (internal or external), the employment test of the called subscriber set or the set of the connecting line, the selection and occupation of service devices and the compilation of the conversation path are determined from the received information.

The long-distance communication channels (PM and digital communication channels) provide automatic and semi-automatic types of connections depending on the type of oncoming station connected at the opposite end of the communication channel. At the same time, an outgoing automatic and an incoming semi-automatic connection via a communication channel are provided. The transit connection in the telephone exchange 6 is carried out between long-distance communication channels in automatic and manual modes through block 39 channel field and block 41 channel sets. The establishment of a transit connection via long-distance communication channels in manual mode is carried out by the station operator with the help of unit 7 RMOT.

Block 7 RMOT is intended for connecting terminal devices to subscriber, connecting lines and communication channels, making and receiving calls, as well as negotiating the established path in the manual service mode of the telephone exchange 6.

Block 7 RMOT is a personal computer such as a laptop. It is designed to issue a control command to the control device 40 to connect the selected input and output in the switching field of unit 4. The portable computer has colloquial and calling devices, with which the operator connects to the channel or subscriber, conducts a survey of subscribers, provides a call to channels and communication lines, and also transmits information about the required connections to the station control device.

A personal computer implemented on the basis of electronic modules and computing nodes of the Baget family of computers can be used as a personal computer of block 7 of the RMOT [4, 5]. At the same time, the computer includes a system unit consisting of a central processor and electronic modules BT01-414 and BT01-416, made on the basis of a domestic microprocessor, a system bus, and specialized software supplied on a hard disk drive. The BT01-414 module is a software-controlled electronic module that implements the protocols of the physical and channel levels. This module is designed to transmit (receive) data and voice information over communication channels using standard protocols for exchanging data and voice information TAPI or in accordance with the EIA RS-232-C standard. These modules implement the combined packet data and voice information, as well as relay data streams in the form of corresponding files.

The first 8 and second 26 cable entry blocks contain connecting and switching elements to which connecting cables from interacting objects and stations are connected using cable connectors.

Deployment of subscriber telephone networks using four-wire and two-wire telephones is carried out by connecting four-wire 1 and two-wire 2 ALs to block 3 input lines and checking their health from block 3 to telephones of subscribers.

Making a call, establishing a connection and conducting telephone communication on these lines is carried out according to well-known principles and algorithms [3].

The connection with the subscriber of the PBX system or the Central Bank is as follows.

The process of establishing a connection at the station takes place in two stages. At the first stage, in the free search mode, a sample is made and a free service device (register) is selected, as well as connected to the caller’s line. At the second stage, the caller is switched to the callee through the switching field. Connection establishment control is provided by a telephone exchange control device 40.

When a subscriber picks up the handset from the SLT via AL 1, a direct current call is sent to the telephone exchange 6. At the telephone exchange 6, a loop is formed by looping a loop and a station ready signal for dialing is sent from the subscriber set to the subscriber’s set (“OS” signal — station response).

By the “OS” signal, the called subscriber dials the number of the calling subscriber, which is fixed in the register. Having fixed the number, the register is connected to the control device (marker) and transmits to it information about the number of the called subscriber. According to the received information, the station control device determines the type of communication (internal or external) and provides a sample of the subscriber’s set of the called subscriber for employment. If the called subscriber is busy, then the control device turns off and turns off the service device (register), and from the subscriber set circuit, the calling subscriber receives a busy signal. If the called subscriber is free, the control device tests free service devices and selects one of them to connect the subscribers to each other, and then gives a command to the switching field unit to connect the subscriber sets of the called and calling subscribers. After that, the control device is turned off and further maintenance of the connection is made from the service device, which sends an alternating current call to the line of the called subscriber, sends the tone “Call control” to the line of the calling subscriber, receives a response signal from the called subscriber and puts its circuit into a talk state , provides power to the microphones of telephone sets of both subscribers, creates circuits for keeping two switching points in working order, receives a hang-up signal and stvlyaet disconnect subscribers.

The negotiation path includes: TA and the subscriber line 1 of the calling subscriber, block 3 input lines, block 4 of the subscriber cross, subscriber sets of the calling and called subscribers block 37 sets of four-wire AL and block 39 of the switching field of the telephone exchange 6, block 4 of the subscriber cross, block 3 input lines, four-wire AL 1 of the called subscriber and then to the TA of the called subscriber.

The path for connecting subscribers of two-wire AL 2 additionally includes a block 5 of differential systems. The rest of the connection process is similar.

With outgoing external communication via long-distance communication channels, the first stage of connection is carried out in the same way as with internal automatic connection. At the second stage, the dialed number is fixed by the telephone exchange control device and it determines the required direction of the called subscriber’s search, selection of one of the free channel sets and switching points in the switching field unit. Then, the channel set of the channel sets block of the station is included in the work, which transmits the number of the called subscriber via the channel to the oncoming station. After the response of the oncoming station about connecting the called subscriber to the line, the path is switched off for negotiating between subscribers.

With automatic incoming external communication, the call is received by the set of the long-distance communication channel, the control device is turned on, which, having received information about the number of the called subscriber of the internal communication, gives a command to the switching field unit to switch the path from the communication channel to the subscriber line of the called subscriber.

The subscribers of the four-wire AL 1 subscribers with the subscribers included in the long-distance communication channels are carried out along the path, including: TA and AL 1 of the calling subscriber, block 3 line input, block 4 subscriber cross, block 37 sets of four-wire AL, block 39 switching field, block 41 channel kits, electronic cross 20 digital channels, the first 16 or second 17 individual encoders, electronic cross 12 analog channels, the first cable entry unit 8, SL 9 or SL 10 and further along the PM / CC channel or radio channel to the opposite side - a illogical station, which includes the called party.

When connecting the first 16 and second 17 individual encoders via a ten-wire interface directly to the telephone exchange 6 (to the channel kit block 41), the subscriber’s connection path occurs along the following lines: SLT and AL 1 of the calling subscriber, block 3 of line input, block 4 of subscriber cross, block 37 sets of four-wire AL, block 39 switching field, block 41 channel sets, the first 16 or second 17 individual encoders, electronic cross 12 analog channels, the first block 8 cable entry, SL 9 or SL 10 and then on the channel TCH / TsK or rad to the channel to the opposite side - a similar station to which the called subscriber is included.

When using the first 18 and second 19 group encoders to transmit information through them to the connection path of the four-wire AL 1 subscribers with the subscribers included in the long-distance communication channels, the first 13 or second 14 UPS of the PM (when operating via the PM channel) or UPS of the PMR 15 are additionally included (when working on the radio channel). In this case, the connection occurs along a path including: TA and AL 1 of the calling subscriber, block 3 line input, block 4 subscriber cross, block 37 sets of four-wire AL, block 39 switching field, block 41 channel sets, electronic cross 20 digital channels, the first 18 or second 19 group encoders, electronic cross 12 analog channels, the first 13 or second 14 UPS TCH (or UPS TCHR 15), electronic cross 12 analog channels, the first block 8 cable entry, SL 9 or SL 10 and further on the channel TCH / CC or radio channel to the opposite side - a similar station to which the called party is included.

The mode of encryption of information transmitted via PM and digital communication channels is carried out by including the first 16 and second 17 individual encoders, the first 18 and second 19 group encoders in the compiled negotiation path.

When using the first 16 or second 17 individual encoders, its inclusion in the tone frequency channel is carried out between the block 41 channel sets of the telephone exchange 6 and the PM channel through the electronic cross 20 digital channels. The negotiating path goes along the following path: the PM channel from the channel input-output of channelization equipment according to SL 9 through the first cable input unit 8, the inputs and outputs of the electronic cross of 12 analog channels are transmitted to the linear input-output of the first 16 individual encoder, in which removal of the cipher, conversion using the own ARPU of the received signals from digital to analog and transmission in analog form from the station input-output of the first 16 individual encoder through the block 20 is fixed for the first data channel encoder block 16, a set 41 of telephone station sets of channel 6 in which the reception of the ringing tones and the formation of control signals. In the future, the processes of establishing a connection occur similarly to those described above when working on PM channels and digital communication channels in unencrypted form.

When using the first 18 or second 19 group encoders to work on tonal frequency channels, the encrypted information from the channel input-output of the equipment via SL 9 through the first cable input unit 8, the electronic cross inputs and outputs of 12 analog channels, the first 13 or second 14 OOPS TCH ( or UPS ТЧР 15), the electronic cross of 12 analog channels is transmitted to the linear input-output of the first 18 group encoder (or to the linear input-output of the second 19 group encoder). In group encoders 18 or 19, the received information is converted into a discrete form and fed to one of the channel inputs of blocks 18 or 19, in which the cipher is removed. The decrypted information from the output of one of the channels of the first 18 or second 19 group encoders is fed to the linear input-output of an electronic cross of 20 digital channels and then the information is transmitted to one of the channel sets of the channel channel sets 41, in which ringing signals are received and control signals are generated.

When manually servicing subscribers, all operations to establish connections are carried out by the operator of the telephone exchange 6 with the help of the unit 7 PMOT, which is connected to the device 40 of the control station.

The work of the station operational telephone and documentary communications over a packet-switched network is carried out using a combined multiplexer 22, a switching cryptographic router 23 and a LAN switch 25. The tract for voice communications, data exchange and e-mail includes: SL 11 for receiving a digital stream E3 (or E1), the first cable input unit 8, a combined multiplexer 22, a switching cryptographic router 23, an Ethernet line, a LAN switch 25, and a second cable entry unit 26 and FOCL 29, at the other end of which data terminal equipment or workstations installed on remote workstations of officials are connected through a similar LAN switch; At the same time, for counter-interaction on the exchange of information at the other end of the trunk 11, a combined multiplexer is activated, similar to the multiplexer 22, with the help of which the formation of one two-channel FOCL is provided, through which information is transmitted at a speed of 34368 kbit / s.

In this case, information transfer is carried out by formalized data packets prepared using personal computers AWP BPM DL, in accordance with the protocols of IP-telephony networks and data exchange. In this case, data packets from the computer of the aforementioned AWP are sent to the LAN switch. In the LAN switch, the signals of the received data are converted from electrical form into optical signals, which are transmitted via FOCL 29 through the second cable input unit 26 to the LAN switch 25 of the telephone and document communication station, where the optical data signals are converted back into electrical signals in the form of digital flow E1. From the output of the LAN switch 25, the digital stream E1 at the Ethernet interface is fed to the switching cryptographic router 23, in which the data is encrypted and the encrypted data from the output of the block 23 is sent to the combined multiplexer 22. In the multiplexer 22, several digital streams are combined into a group signal E3 and the group is converted signal E3 from an electrical view into an optical signal, which through the first block 8 of the cable input via СЛ 11 enters through an optical cable to a similar multiplexer interacting Dancing. In the multiplexer of the interacting station, the data signals are inversely converted from the optical form into the electrical signal of the E3 stream and the group signal of the E3 stream is divided into several digital signals E1, which are then sent to the officials workstation.

It is possible to organize the exchange of data and e-mail between remote workstations of officials and the telephone exchange operator along a path that includes: IP server 42 of telephone exchange 6, an Ethernet line and then through the first inputs and outputs of the station side of the switching cryptographic router 23, an exit is made to the formed path exchange of documentary information. Moreover, the data exchange rate can be up to 2 Mbps.

The organization of the data exchange path is controlled by the operator using an external UU 24, which is connected to the information and control input-output of the subscriber side of the switching cryptographic router 23 via the E-line at the RS-232 interface.
