Chapter 1 Introduction to Telecommunications
Chapter 2 Telecommunications Technology Fundamentals
2.0 Objectives
Upon completing this chapter, you should be able to: • Define the following terms; transmission lines, circuits, trunks, virtucal circuits, bandwidth, analog transmission, digital transmission, internet governance. • Differentiate between; line and trunks, PVC and SVC, Narrowband, wideband and broadband, analog and digital transmission, codecs and modems and various standards organization bodies. Describe the various circuit types. Describe the allocation of spectrum for use in communication Name and define the functions of various standard organizations locally and internationally
• • •
This chapter from (Goleniewski and Jarrett, 2006) discusses the types of transmission lines and network connections, the electromagnetic spectrum, and what bandwidth is all about in the emerging broadband era. It looks at the differences between analog and digital signals. Finally, this chapter describes the various standards bodies and their roles in shaping aspects of
2.1 Transmission Lines
Two prerequisites must be satisfied to have successful communication. The first prerequisite is understandability. The transmitter and receiver must speak the same language. It doesn't matter how big or how clean the pipe between the two endpoints. If they're not speaking the same language, they will not be able to understand the message. In the case of data communications, we've resolved these issues quite elegantly: We have software and hardware translation devices that can convert between the different languages that individual computing systems speak. In the realm of human communications, we're about to embark on that exciting journey as well. Through the use of advanced voice-processing systems, in the next five to seven years we should have the ability to do real-time foreign language translation as part of the network service. And of course, some search engines, such as Google, already provide Web page
