Abstract: Telecommunication networks carry infor- mation signals among entities, which are geographically far apart. An entity may be a computer or human being, a facsimile machine, a Tele-printer, a data terminal and so on. The entities are involved in the process of infor- mation Transfer which may be in the form of a telephone conversation (telephony) or a file transfer between two computers or message transfer between two terminals etc. Today it is almost truism to state that tele communication systems are the symbol of our information age. With the rapidly growing traffic and untargeted growth of cyberspace, telecommunication becomes a fabric of our life. The future challenges are enormous as we antic- ipate rapid growth items of new services and number of users. What comes with the challenge is a genuine need for more advanced methodology supporting analysis and design of telecommunication architectures. Tele communication has evaluated and growth at an explosive rate in recent years and will undoubtedly continue to do so. The communication switching system enables the universal connectivity. The universal Connectivity is realized when any entity in one part of the world can communicate with any other entity in another part of the world. In many ways telecommunication will acts as a substitute for the increasingly expensive physical trans- portation. The telecommunication links and switching were mainly designed for voice communication. With the appropriate attachments/equipment’s, they can be used to transmit data. A modern society, therefore, needs new facilities including very high bandwidth switched data networks, and large communication satellites with small, cheap earth antennas.
