The Fundamentals of Timing and Synchronization for Digital Communication Networks.

The telecommunications industry is evolving toward integrated end-to-end digital communications networks. To keep pace with this evolution the telecommunications professional must have a current understanding of digital communications technology. Fundamental to this understanding is the knowledge of timing and synchronization TS for digital communications networks. This assemblage of studies is presented as a reference. It reviews the fundamentals of carrier, bit, and character synchronization. The concept of time as the basic unit for TS is developed. Time scales, clocks, and frequency sources used in timing systems are discussed. TIme and frequency distribution services are described, including LORAN-C and NAVSTAR Global Positioning System GPS. An explanation of time division multiplexing TDM and line codes is given. Network synchronization techniques are examined and classified. Thesis.
