Telecommunication Networks

The course covers issues related to the design and implementation of Telecommunication Networks as well as current issues of administrative and financial regulation of telecommunication infrastructures. The following are presented in more detail: The structure of Public Telecommunication Networks, the principles of multiplexing, the basic Transmission Systems and the Synchronous Digital Hierarchy (SDH). The principles, the basic devices and the most important switching techniques and systems with emphasis on Digital Switching are also presented. Also, issues related to Switching Systems and Signaling Control, Intelligent Telecommunication Networks (IN) and their services are addressed. In addition, the evolution and the technologies of modern access networks are presented: from the ISDN network (services, basic features, architecture, signaling) to the packet switching public telecommunication networks (ATMs, MPLS). The challenges posed by the migration to Ethernet and IP telephony technologies are presented in detail.Analytical issues of NGA networks with particular emphasis on xDSL-based networks and FTTH (FTTH). The above are related to issues related to the liberalization of the Telecommunication Market, Telecommunication Policies and Regulation as well as basic concepts of Administration and Economic Telecommunication Networks and Infrastructures. The laboratory part works as a simulation laboratory of Telecommunication networks using OMNET+ network simulator and models in GNS3.
