ITU-T Timing Recommendations

In this chapter, you will learn the following:

• Overview of the ITU: Describes the general structure of the International Telecommunication Union (ITU), and the part of the organization (the ITU-T) responsible both for standardization and for timing and synchronization. It also categorizes the large number of recommendations and provides detail about how to read and use them.

• ITU-T physical and TDM timing recommendations: Provides an overview of the ITU-T recommendations that concern frequency timing using physical and time-division multiplexing (TDM) techniques such as the synchronous digital hierarchy (SDH).

• ITU-T recommendations for frequency in packet networks: Provides an overview of the ITU-T ...
