utions Benefits anybody selecting or designing timing solutions, especially for those using the PTP telecom profiles Covers the latest standards and functionality from both the standards development organizations and industry Compares and contrasts different approaches to implementation-objectively and with vendor neutrality. There are only two mentions of any Cisco product or router models in this book. From the very first chapters, the book introduces concepts from mobile communications to give you background to the key technology trends and decision points facing today's mobile operators. It also addresses the implementation and characterization of timing for several deployment methods and use cases using best-in-class design practices. The book is divided into the following four parts, each of which contains two to four chapters: Part I, "Fundamentals of Synchronization and Timing," introduces synchronization requirements and timing concepts for communications networks. It includes the following chapters: Chapter 1, "Introduction to Synchronization and Timing," covers the fundamental concepts of what timing is, what type of synchronization exists, why it is needed, and how it can be sourced and transported. Chapter 2, "Usage of Synchronization and Timing," covers the uses of timing, where it is ap- plied, and what sort of industries need time-although with particular emphasis on telecommunications Chapter 3, "Synchronization and Timing Concepts," starts with the specifics of synchronous networks and the foundational aspect of the topic: clocks, timing reference sources, the time distribution network, and the application use or consumption of the timing signal. It also covers the GNSS satellite systems in some detail and describes various methods of transporting syn- chronization information and timing signals. Part II, "SDOs, Clocks, and Timing Protocols," introduces the relevant standards development or- ganizations, explains clocks in detail, and discusses various timing protocols. It includes the follow- i
