The scheme of the proposed device is shown in Fig 2, where it is indicated:

1 - control device and problem solving;

1.1 - a device for constructing a formalized request;

1.2 - database (DB) of behavior patterns;

1.3 - device for applying patterns of behavior;

3 - information storage device;

The proposed device contains a control and problem solving device 1, an input / output and information visualization device 2, an information storage device 3, a simulation device 4 and a calculator 5. The control and problem solving device 1 is implemented as a formalized query building device 1.1 connected via an information bus to the database of behavior patterns 1.2, which is connected to the device for applying the behavior pattern 1.3, the control output of which via the control bus is connected to the storage device info 3, which is connected through an information bus to the corresponding information inputs of the simulation device 4, input / output and information visualization devices 2, one of the information outputs of which is connected via the information bus to the information input of the information storage device 3, and the other output - to the information input a calculator 5, the information output of which through an information storage device 3 is connected to an input-output and information visualization device 2.

The information bus from the simulation device 4 is connected to the information input of the device for constructing a formalized request 1.1.

The proposed device operates as follows.

The device automatically checks the correctness of the telecommunications system under development based on the input data on the structure of the system with the issuance of the verification result, as well as recommendations for correcting an incorrectly composed circuit or circuit element.

Technically, the control device and problem solving 1 is implemented on the basis of a computer equipped with means for inputting information by the operator and means for visualizing the circuits of a telecommunication system. The computer is equipped with input-output ports that allow you to connect external storage media, a printing device to the device, and connect computers to each other. A computer must be installed on a computer that implements a telecommunication system based on the multi-level mathematical model described in [1], and a database management system (DBMS) is installed, for example, MS SQL Server, Oracle, etc., moreover, in the database pre-developed communication system design options are stored. The device for constructing a formalized request 1.1 receives data on the state of the system from simulation device 4, then, based on the received data, a query is constructed to the database of behavior samples 1.2, according to which, if necessary (breaking a communication channel or a malfunction of the technological structure), another option is selected building a communication system from among those described in the database.

For an operator, a telecommunication system is represented using an input / output device and visualizing information 2 in the form of a diagram, and for the purpose of machine processing, the entered circuit is converted by a calculator 5 into a hypergraph whose vertices are the ports (connection points) of generalized routers (any devices capable of receiving, transmitting or redirect information), and edges - connectors (physical or logical channels) connecting these ports. From a model point of view, a generic router (OM) is some set of ports. A generic router that cannot be represented as two generic routers connected by connectors will be called an elementary generic router (EOM). This concept corresponds, for example, to one radio station, a set of data transmission equipment (ADF), etc.

Simulator 4 simulates the elements of a telecommunication system and is implemented using software that implements a mathematical model, as well as by connecting to a computer devices simulating elements of a telecommunication system. The latter applies if it is necessary to simulate the functions of an element of a telecommunication system in full (taking into account the specifics that go beyond modeling through the use of a mathematical model), or in the case of high performance requirements of the claimed device when working with complex (large-scale) circuits.

Information generated by the device during operation, as well as stored circuits and operator action logs, are stored in the information storage device 3, implemented by using an information storage device (a hard disk drive and a computer main memory or an external storage medium).

The proposed device provides the task of the classes of elements of the telecommunications system and the creation of instances of the classes of elements of the telecommunications system, displaying them based on the graphic primitives embedded in the device. The sets of all ports and connectors are broken up by different families of subsets - classes of ports and connectors. For each class of ports, classes of ports and connectors are specified, such that ports from the specified classes can be connected by connectors of the specified class to the selected port. For each port, the maximum number of connections to it is specified, which determines the maximum number of connectors that can be connected to this port.

Also, the proposed device performs the processing of input raw data and the automatic formation on their basis of graphic and tabular descriptions of telecommunications systems. Operations with a telecommunication system and its elements are represented as operations on a graph. EOMs are considered as discrete signal converters, while some EOMs may have memory, i.e. store signals. The device allows you to specify the classes of EOM, as well as set the number and set of properties of each class.

In addition, the device allows the assignment of identifiers and addresses to circuit elements in both automatic and manual mode.

In the process of creating a scheme, an electronic log of operator actions is maintained. The correctness of the generated circuit is also automatically controlled. Based on the automatic analysis of the operator’s actions log, as well as on the basis of the automatic analysis of the correctness of the scheme, an assessment is given to the operator. Based on the analysis of the schemes compiled by the operator, the issuance of assessments, as well as the logging of the actions of the operator, the process of training the operator to design telecommunications systems, draw up communication schemes is built.

The device provides the preservation of previously created circuits for the purpose of their reuse or transfer using external storage media.

Provided external media are connected to the device (for example, magnetic, optical media, flash-based media), the device provides electronic (machine) storage of circuits on external storage media, as well as reading from circuits previously stored on them.
