How to Synchronise Telecommunications Networks

How to Synchronise Telecommunications Networks pdf

To meet the telecommunication needs of a fast growing global economy, existing networks are being enhanced using new technologies and many new network operators are emerging after deregulation. Network synchronisation is very important for switching, transmission and data networks, such as telephony, Plesiochronous Digital Hierarchy (PDH), Synchronous Optical Network (SONET), Synchronous Digital Hierarchy (SDH), and Asynchronous Transfer Mode (ATM) networks. It is essential that the telecommunication systems in these networks are synchronised to meet the Quality of Service (QoS) demanded bynetwork users. A network planner has to understand the object of network synchronisation, the related international specifications, the general synchronisation network design requirements, plus the merits and limits of different synchronisation methods before planning a synchronisation network.
