Chapter 14: Telephony and Cellular Networks 14-1 the System View
Chapter 14: Telephony and Cellular Networks Chapter 14 Objectives At the conclusion of this chapter, the reader will be able to: • Describe the overall topology of the U.S. telephone network. • List the electrical characteristics of an analog POTS subscriber local loop. • Describe the operation and characteristics of a typical analog CPE • Describe the DTMF signaling standard. • Describe the digital signaling standards used in the telephone system. • Describe the operation of digital traffic switches. • Compare and contrast AMPS and PCS service characteristics. • Describe how subscriber signals are carried through a PCS network. • Given a frequency reuse map for a PCS market, identify the groups of frequencies utilized by each cell in the market. • Describe the operation of DSL/ADSL subscriber services. • Describe a typical installation for VoIP equipment. “Mr. Watson, come here, I want you.” These historic words were the first speech to be successfully transmitted through wires, uttered by Alexander Graham Bell to his assistant in March of 1876. It was the beginning of the second wave of the telecommunications revolution, started by the invention of the telegraph in 1833. Now a basic part of modern life, the telephone system is one of the most creative and complex achievements of humankind. Over its lifetime, it has directly influenced and benefited from many advancements in electronic technology. The modern telephone system uses analog and digital circuitry, computers, advanced signal encoding, and of course a healthy dose of wireless technology. Let’s see how it all works together. 14-1 The System View In the earliest days of the telephone, no more than a few hundred telephone sets existed. -

Inventing the Communications Revolution in Post-War Britain
Information and Control: Inventing the Communications Revolution in Post-War Britain Jacob William Ward UCL PhD History of Science and Technology 1 I, Jacob William Ward, confirm that the work presented in this thesis is my own. Where information has been derived from other sources, I confirm that this has been indicated in the thesis. 2 Abstract This thesis undertakes the first history of the post-war British telephone system, and addresses it through the lens of both actors’ and analysts’ emphases on the importance of ‘information’ and ‘control’. I explore both through a range of chapters on organisational history, laboratories, telephone exchanges, transmission technologies, futurology, transatlantic communications, and privatisation. The ideal of an ‘information network’ or an ‘information age’ is present to varying extents in all these chapters, as are deployments of different forms of control. The most pervasive, and controversial, form of control throughout this history is computer control, but I show that other forms of control, including environmental, spatial, and temporal, are all also important. I make three arguments: first, that the technological characteristics of the telephone system meant that its liberalisation and privatisation were much more ambiguous for competition and monopoly than expected; second, that information has been more important to the telephone system as an ideal to strive for, rather than the telephone system’s contribution to creating an apparent information age; third, that control is a more useful concept than information for analysing the history of the telephone system, but more work is needed to study the discursive significance of ‘control’ itself. 3 Acknowledgements There are many people to whom I owe thanks for making this thesis possible, and here I can only name some of them.
