The article defines the system features, properties and characteristics of information and telecommunication networks of automated environmental safety systems: information reliability and proven efficiency as a fundamental characteristic of system perfection. The main task of this research is to standardize the highest level of information and telecommunications networks architecture that provide the creation, processing, storage, deletion and transportation of information. In this case, the architecture is considered as a single for: all types of networks (including network services): optical transport network, Internet network (data network), fixed telephone network, mobile network and all types of products, customers, services, resources, aspects of management. A very important requirement is that the system architecture should not change when changing the structure of products, market requirements or the structure of the company. Standardization of information systems architecture involves: defining a complete list of architecture components; determination of functional boundaries of components; definition of interfaces (protocols) of interaction of components. The main purpose of architecture standardization is: to reduce the implementation of telecommunications services by reducing the time for implementation and modernization of information systems, and increase the efficiency of implementation of information systems, as well as reduce costs for their creation and operation by: avoiding duplication of functions; use of open interfaces; repeated use of the same type of elements. The research concerns the structural synthesis of the architectures of four main telecommunication networks: transport, IP, mobile and fixed. Eight sets of network resources (levels) were selected to standardize each network architecture. Based on the results of the analysis, it is possible to draw a conclusion about the development potential of each network depending on the trends of modern telecommunications services. The telecommunication services means of production architecture, which include platforms of network resources and network services, is considered. The article proposes a methodological basis for the synthesis of information and communication technology systems in order to establish a single information platform, which is presented as a universal architecture of information and communication systems. The messaging service is considered in the context of: one workstation, one domain and interconnection between domains. The efficiency of information transmission systems is considered. When evaluating different communication systems, two indicators were taken into account: efficiency and noise immunity; their combination gives a fairly complete description of the system. The most perfect system is the one that provides the greatest efficiency at a given noise immunity or, conversely, the greatest noise immunity at a given efficiency.
