Utility Model Implementation

The device has a modular structure and consists of one master module, which contains a central processor unit 1, an information storage device 2, an input / output and information visualization device 3, an indication device 4, and one or more slave modules that contain a slave processor unit 5 , information storage unit 6, input / output and information visualization unit 7, subscriber unit unit 8, line termination unit 9, display unit 10.

The Central processing unit 1 is designed to monitor the operation of the device as a whole by submitting control commands to the slave processor unit 5; the submission of control commands to the display device 4 through the input-output device and visualization of information 3; recording in the long-term memory of the information storage device 2 current settings of the “Primary multiplexer hardware simulator”; reading from the long-term memory of the information storage device 2 recorded settings of the “Primary multiplexer hardware simulator”.

Information storage device 2 carries out long-term storage of information about the settings of the “Primary Multiplexer Hardware Simulator”, as well as the operational storage of service information necessary for the operation of the “Primary Multiplexer Hardware Simulator”.

The input-output and information visualization device 3 carries out two-way broadcast of control and information signals between the central processing unit 1, the information storage device 2, and the indicating device 4.

An indication device 4, based on the control signals of the central processing unit 1, obtained by means of an input / output device and information visualization 3, outputs acoustic and visual indications to the front panel of the device in order to monitor the operability and current operating mode of the device as a whole.

The slave processor unit 5 interacts with the central processor unit 1 in order to obtain control commands for configuring the subscriber unit block 8, the line termination block 9, the indication block 10, and also transmitting an information signal about the state of the subscriber unit block 8, the line termination block 9, block indication 10; supply of control commands to the block of subscriber devices 8, the block of linear endings 9, the display unit 10 through the block input-output and visualization of information 7; recording in the long-term memory of the information storage unit 10 current settings of the slave module; reading from the long-term memory of the information storage unit 10 recorded settings of the slave module.

The information storage unit 6 carries out long-term storage of information about the settings of the slave module, as well as the operational storage of service information necessary for the operation of the slave module.

The input-output and information visualization unit 7 carries out two-way translation of control and information signals between the slave processor unit 5, the information storage unit 6, the subscriber unit 8, the line termination unit 9, and the display unit 10.

The block of subscriber devices 8 performs direct and inverse conversion of information and control signals from subscriber terminals and the reception / transmission of information and control signals to the input-output and visualization block 7.

Block of linear endings 9 matches the interfaces of the counter-running “Hardware simulators of the primary multiplexer” for receiving / transmitting the information stream from the linear path to the input-output and visualization unit 7.

The display unit 10, based on the control signals of the slave processor unit 5, obtained by means of the input-output unit and information visualization 7, outputs acoustic and visual indications to the front panel of the device in order to monitor the operability and current operation mode of the slave module.

The utility model works as follows.

When starting the “Primary multiplexer hardware simulator”, the central processing unit 1 of the host module performs a self-test, in which the health of the input / output and information visualization device 3, information storage device 2, and display device 4 is checked; initiates a request to the slave processor unit 5 of each slave module for self-testing and the issuance of information about the seat and the current operating mode of the slave module.

When receiving a request for a self-test and issuing information about the seat and the current operating mode, the slave processor unit of each slave module performs a self-test, in which the health of the information storage unit 6, the input-output and information visualization unit 7, the subscriber unit unit 8, the line termination unit is checked 9, display unit 10; carries out determination of a seat. After completing the self-test and determining the footprint, the slave processor unit of each slave module generates and sends a message to the central processing unit 1 with information about the footprint number and current status.

In the process of operation of the “Hardware simulator of the primary multiplexer,” the slave processor unit 5 of the slave module, through the input / output unit and the visualization of information 7, polls the block of subscriber devices 8 and the block of line terminations 9. In the case of a request to establish a connection from subscriber terminals and / or counter-running "Hardware simulators of the primary multiplexer" slave processor unit 5 of the slave module initiates a request to the information storage unit 6 in order to obtain the current settings Omogoya module. If the current settings of the slave module do not prohibit establishing a connection between subscriber terminals and (or) counter-running “Hardware simulators of the primary multiplexer”, then the connection is established, otherwise it is reset. Establishing a reset connection, setting the operating mode are accompanied by a visual indication on the front panel of the device. Information about all the actions of the slave processor unit 5 of each slave module transmits to the Central processing unit 1 of the master module.

The “hardware simulator of the primary multiplexer” can be used to train communication specialists on working with the primary multiplexer, as well as to ensure collaboration with other hardware simulators and communication terminal devices. Moreover, all signals incoming and outgoing from a real product are imitated in full.

Thus, the use of the proposed “Hardware simulator of the primary multiplexer” in the educational process will increase the effectiveness of training by improving the practical skills of working on the primary multiplexer using informative imitation of information subscriber and linear signals and indication signals, which is difficult when using real products.
