Comprendiendo las telecomunicaciones (Inglés) Tips Telecomunicaciones The global telecommunications network – the largest and most complex technical system that man has created – makes up a substantial part of a country´s infrastructure and is vital to the development of that country. By telecommunications we mean here all processes that render it possible to transfer voice, data and video with the help of some form of electromagnetic system, including optical transfer methods. The telecommunications networks are mainly composed of nodes (exchanges) and links Telephony can manage relatively poor transmission quality because of the redundancy built into natural language and speech, and because people engaged in a telephone conversation can easily overcome temporary disturbances and interruptions by repeating what they have just said. On the other hand we find a difficult to accept delays in a telephone connection. Data traffic, by contrast, is relatively insensitive to delay (within reasonable limits) whereas poor transmission quality can cause bit errors and a garbled message. For broadband services above 2 Mbits an elaborated packet technique called asynchronus transfer mode ATM has captured the interest of the telecommunications world. PSTN Public Switch Telephone Network PLMN Public Land Mobile Networks ATM Asynchronus Transfer Mode Network Operator or Operator is used to denote a company that administrates a telecommunications network A bearer service solely provides a transport system for exchanging information. By contrast, a teleservice is complete in the sense that – in addition to a transport system – it includes functions for connections, and a uniform language for communication and for shaping the messages conveyed Multimedia a service which contains at least two or the three service types voice, data and video, and which provides a certain degree of interactivity.
