Introduction
The primary purpose of this book is to
describe how telecommunications networks work. Although the technology is
explained at a simple functional level, emphasis is put on how the various
components are used to build networks – fixed mobile, voice and data. I
have tried to pitch the explanations at a level that does not require an
engineering knowledge. Indeed, it is hoped that this book will be helpful to
the wide range of people working in the telecommunications industry: managers
who specialize in marketing, customer service, finance, human resources,
public relations, investor relations, training and development, and legal and
regulation. However, many of the engineers in the industry may also appreciate
an understanding of aspects beyond their specializations that this work aims
to provide.Analog Circuit Design: Scalable Analog Circuit Design, High Speed D/A Converters, RF Power Amplifiers
Telephony Network
A telephone exchange serves many telephone
lines, enabling any line to be connected to any other. In a small village
all the lines could easily be connected to a single telephone exchange,
since the distances are short. However, if telephone service needs to be
provided to a larger area, the question arises as to how many exchanges are
needed. This is where a region of the country has a large population of
telephones to be served. They could all be served by one central large
exchange or by several smaller exchanges. Obviously, the lengths and hence
costs of the telephone lines reduces as the number of exchanges increases,
but this saving is offset by the increase in costs of exchange equipment and
buildings. In addition, a link needs to be established between each exchange
to ensure full connectivity between all telephones in the region.
