The telecommunications network is a global system of equipment and means that ensures the connections between the users of communication services, with the transmission and reception of the information involved. It is a set of communication nodes, in which processing procedures take place for the transmission and reception of information signals, switching connections and choosing routes between nodes to make connections between sources and destinations of communications, and a set of links between these nodes, made in a variety of technologies.

This volume contains 5 chapters in which the different processes and types of systems within the telecommunications network are presented.
