Abstract
This article is a logical continuation and concretization of the authors’ work [1]. Dedicated to the consid-eration of the prerequisites and possibilities of creating a coher-ent public communication network in the interests of end-to-end digital technologies. Justification and use of the core of the time-frequency support of the fixed network as a basis for the syn-chronization system of 5G and 6G standards communication networks. Based on the ITU-T Recommendations, an analysis was carried out on the current state of the primary reference sources of frequency and time (Primary Reference Timing and Clock – PRTC), the basic requirements for them in terms of fre-quency and time signal accuracy, the possibility of implementing promising PRTC and enhanced PRTC – ePRTC on domestic equipment. Precision characteristics of frequency and time sig-nals on the network sections from the sources of the State Time and Frequency Service to the ePRTC, between the PRTC core of the backbone network and the wireless communication network synchronization system. The norms for the permissible errors of the main nodes of the network elements are given, their feasibil-ity is shown.
Keywords: time scale, network synchronization, time-frequency support, network time protocols NTP, RTP, methods of comparison and distribution of time scales, backbone communication network and communication networks of 4G, 5G and 6G standards, coherent network.
