JSC «KNIITMU» has been created in 1959 for the development of new and enhancement of existing telegraphs to provide the country with high-quality document communication. At the 60th years the scientific school of creation of telegraph and facsimile equipment was founded at the enterprise. Within this scientific direction the researches of distortions of telegraph marks and methods of optimization of signal reception were conducted in real communication channels. The probability laws of allocation of various type distortions have been established, the dependences of error probability for different types of modulation are described, valuable practical recommendations for optimal adjustment of parameters of telegraph receivers are made. Simultaneously the development of telecode communication equipment was carried out at the enterprise. The concatenated noise-resistant codes with high correcting ability and original methods of code cycle synchronization have been used in the equipment. The standard of radio line "Pereval", which is wide spread today, uses powerful concatenated BCH - Reed-Solomon code to provide noise resistance. The redundancy of Reed-Solomon code can vary on the transmitting side depending on channel quality (the short or long code), providing the full compatibility without changeover. Modern adaptive signal-code constructions with variable parameters are used to operate in difficult noise conditions. These constructions automatically and purposefully are changed depending on communication channel quality. Besides constant control and monitoring of communication channels are carried out. For control of the noise-resistant code parameters the effective algorithm of double-circuit adaptive control is used. The equipment steadily operates in the conditions of peace time and during the special period. Actually it is described the system, capable to function in extreme operating conditions, and this can be reached only at the expense of substantial increase of its survivability and reliability. The main method to increase the system survivability and reliability is the rational combination of stationary and mobile communication centers, complex usage of various communications means for information exchange, the usage of highly reliable component base and special circuit and algorithm decisions. The modern development of terminal telecode equipment is based on the scientific principles providing the creation of robust networks with multidimentional routes of data transmission, optimization of routes of transmission of different information in the conditions of networks topology change, network coding, introduction of time, code, space and functional hardware-software redundancy and control mechanisms. The created equipment is highly evaluated by the customers. The employees gained invaluable scientific and technical experience during the operation on the customer objects. Important scientific and technical contacts with the leading scientific organizations and customers enterprises have been set. Today the development of scientific directions is the great importance for the enterprise, providing the appropriate technical level of created equipment and its competitiveness.
