Abstract

A description is given of AT&T´s nationwide synchronization network along with a tutorial on the importance of and need of synchronization. The primary reference clock (PRC) is described along with its verification methodology, capabilities, and performance. The clock and transmission models are discussed along with methods of specifying and testing clock performance. Planning tools and methodology for the synchronization of private digital networks are presented. An expert system that uses the clock models to prepare the optimum performance synchronization plan for a private network is introduced.<>
