Abstract

In modern synchronization networks, PRC primary synchronization devices have become an integral component necessary to ensure stable operation and long-term accuracy of reference signals. But their high cost and insufficient use to provide only one unit lead to the need to find other options. Frequency standard manufacturers supply PRS as dedicated hardware without redundancy, whereas in modern synchronization networks PRS must be redundant in order to maintain the required quality of the reference signals. The paper considers the possibilities of modernization of the complex of primary devices of the synchronization network using the example of PJSC “Ukrtelecom” and analyzes the features of using the BesTime algorithm. The main advantages of the protocol in ensuring stable and high-quality operation of the synchronization network are considered. The basic principle of operation of the BesTime algorithm is described, as an algorithmic method of PRC reservation during modernization, the basis of the algorithm is the “triangular hat” method, and as a result, the resulting signal with the best characteristics of one of the three nodes is obtained according to the algorithm. It is demonstrated how the use of the algorithm makes it possible to divide a complex network of synchronization channels into simple and well-controlled fragments with equally high quality reference signals.
