Reference Node for Forming the Time Scale of a Coherent Public Communication Network

This article is a logical continuation and specification of the works of the authors on the justification and use of the core of the time-frequency support of the transport network as the basis for the synchronization system for 5G and 6G networks. It considers the possibilities of implementing the reference synchronization node of a coherent public communication network - the coherent primary reference time and clock (cnPRTC), on domestic equipment. It is based on the ITU-T Recommendations both in terms of the structure of the cnPRTC and in terms of the accuracy characteristics of the output frequency and time signals. The norms for the permissible errors of the main units are given and their feasibility is shown.
