Аннотация

Subjects of the research: The diagnostics of data transmission systems’ (DTS) elements under operation terms, methods of the control of DTA (data transmission apparatus) and diagnostics of digital devises on the base of signature analysis. Purpose of work: Investigation and development of effective control methods and diagnostic of data transmission systems’ elements. .Method of research: On solving of given problems analytical and program methods of investigation have been used, including elaborated models and methodic with following processing and analyses of the received results. Analytical methods were based on probability theory, flow - chart theory, reliability theory, algebra logic theory, machine modeling theory. The results obtained and their novelty: The cascade model of error source of discreet channel and the strategy of diagnostics and restoring the efficiency of DTS elements. The mathematic model of embedded control over DTS elements with and without self control and evaluation of volumes value and efficiency. Evaluation methodic of sample signatures reliability and calculation. The algorithms of despairs detection at signature analysis application, minimizing the time of search. An imitation model for evaluating the methods of compact testing and sample signatures shaping. Practical value: The elaborated methodic, algorithms and programs are recommended for practical use at designing of control - diagnostic provision at the stage of operation of data transmission systems. Degree of embed and economic cffcctivitv: The results of dissertation work have been adopted in AK «Uzbektelecom». The theoretical and practical results have been used at TU1T on «Telecommunications» specialty and 5A522205 - «Communication networks and control systems» specialty. Field of application: The proposed methodic, algorithms and programs could be widely used at operation of data transmission systems, development of control - diagnostic supply of digital systems and devices of telecommunication equipment.
