Boundary Parameters for a Qualitative Assessment of Digital Communication Channels with Specified Reliability Characteristics

In the classical theory of telecommunications, an indicator of reliability is the probability of an information bit error. In modern international standards and recommendations, there is a hierarchy of quality indicators of the communication channel based on measurements, which is not related to the classical theory of noise immunity. The procedures for measuring the quality indicators of information transmission are possible only when using an already existing telecommunication system. The use of the classical theory of noise immunity makes it possible to provide for the correspondence of the energy parameters to the necessary quality indicators for the future communication system. The research defines the values of the characteristics of digital communication channels with the specified reliability and the boundary characteristics for quality work in multiservice networks.
