The procedure for working in a closed communication network using a working (RSZ-R) and transport hub (UTSZ-R) closed communication station is given below.

The procedure for working in a data transmission network using the UTSZ-R, RSZ-R nodal and subscriber kits is divided into the work of the network administrator, as a rule, a security information officer (OBI), and a network user.

The OBI administrator prescribes access rights to information, enters passwords, and sets up address information for subscribers.

At the end of the work, the OBI administrator scans the logs to determine attempts to unauthorized access to information.

At UTSZ-R, the security administrator ensures information security with the help of the SZI Nevod 1.0 software, certificate of the Ministry of Defense of the Russian Federation No. 77 dated 05.02.01

At the RSZ-R, the security administrator ensures the security of information using the Labyrinth-M hardware-software complex for information protection (APKZI).

The user (operator, official) at the UTZZ-R performs switching on the station, entering the password and monitoring the behavior of communication channels, information about which is displayed on the station’s monitor.

Further, the station operates in automatic mode, and operator intervention is required only in the event of a channel failure.

The user of the RSZ-R (operator / officer) prepares for the transmission of the message. One or more files can be attached to the message.

A message is assigned a number of generated attributes: subject, urgency, information stamp, subscription number, last name of the official who signed the document.

When composing a message, it is possible to use phrase templates and automatically break up sent messages into parts, depending on the category of urgency.

Automatically compress sent messages.

The subscriber or subscribers of the message recipient is selected from the list of available subscribers.

An application for sending a message is formed: the application is queued depending on the priority (urgency category).

The TS-NET transport system is always in standby mode, it selects a request from the queue and starts sending messages.

When transmitting information, the integrity of the received blocks is checked and the message is stitched together.

When the connection is disconnected, the connection is automatically established, and transmission continues with the message on which it was interrupted.

In the process of receiving and transmitting, subscribers can exchange short messages, this exchange is carried out against the background of the file transfer.

Upon receipt of the message, a receipt for the delivery of the message is generated and sent. After viewing the message, the recipient subscriber generates a receipt to bring the message to the recipient.

The recipient is given information on the screen about the received messages and an audible alarm about newly received messages.

Through the UTSZ-R junction complex, transit message transmission can be carried out.

Information is stored in magazines until a certain date, with the possibility of archiving magazines.

The text of the message "copies of electronic journals" is printed.

The message text is automatically deleted after the expiration of the retention period.
