* Convergence is confusing. Convergence is critical. And convergence is real. In this book, industry pundit Ray Horak describes how the merging of voice and data networks has evolved and is likely to evolve as we move toward an information-based economy.
* Beginning with the fundamentals of communications technology, the book grounds the reader in basic telecommunications concepts including circuits (dedicated, switched and virtual), switches (circuit, packet, and frame), and the issues involved in digital and analog transmission.
* Describes the rudiments of transmission media, from twisted pair and coaxial cable to satellite and fiber-optic transmission.
* Introduces the basics of voice systems, beginning with legacy networks like key telephone systems and including PBXs, Centrex, Automatic Call Distributors, and Computer Telephony Integration (CTI).
* Explains the fundamentals of data communications, including basic LAN and WAN engineering, modems and other forms of data communications equipment, broadband infrastructure and network services, and the protocols and equipment that make the global Internet a reality.
* Considers some of the emerging technologies and applications just now gaining widespread acceptance, including wireless networks and digital video networks, along with the economic and regulatory forces likely to determine the shape of the networked world of the 21st Century, as well as the speed with which we can expect to see it implemented.
* Previous edition sold 40,000+ copies.

Living in an era of instant communication has certain drawbacks. Not too long ago, the living was simpler. People had one or two telephone numbers, a street address, and access to four or five television channels. Now, we have phone numbers for home, work, mobile phone, fax machine, and pager. We have multiple e-mail addresses. We have access to unlimited information over the Internet. With digital cable or a personal satellite dish, we choose from hundreds of television channels. The communication technology behind this revolution continues to evolve--becoming faster, cheaper, and more prolific. What technology is behind the scenes, and how does all of this information get delivered? That is the question that's answered by this remarkable tome, Ray Horak's Communications Systems & Networks.

Horak explains communication technologies in 15 chapters, using the growing convergence of voice, data, and video as the narrative thread that holds the book together. He starts at the beginning--telegraph and early telephone--and details the progression from analog voice signals to modern high-speed digital networks. Along the way, he emphasizes technical breadth. For exhaustive detail on any one subject, Horak enumerates relevant sources and suggests additional reading at the end of each chapter. This feature makes this book the ideal place to start when researching any communications topic. Another good thing about this book is its pragmatic approach to communications. Horak blends a high-level view of the subject with implementation and deployment issues, as well as the relative costs of different technologies.

This book is valuable for both engineers and managers. It's a perfect resource for inquisitive engineers who are well versed about one area of communications and want to explore the rest of the communications world. For a manager who wants a technical overview of a given subject, the depth is perfect--just enough knowledge to become dangerous.

The conversational style of the book also is a welcome touch. In contrast to technical books that require a can of Jolt to stay awake, Horak presents complex material concisely. Historical perspective is integrated with technical details, and reflects the author's many years of experience. Topics such as the Telecommunication Act of 1996 are explained in the context of technological change, and give the reader a comprehensive overview of virtually all communication technologies. This book is the perfect complement to such industry mainstays as Perlman's Interconnections, Comer's Internetworking with TCP/IP, and Tanenbaum's Computer Networks. --Pete Ostenson --This text refers to an out of print or unavailable edition of this title.

5.0 out of 5 stars Well organized and lucid, February 3, 2000

This review is from: Communications Systems and Networks (Paperback)

This book is not for beginners. If you are looking for a really good beginner's book for non-techies, Annabel Dodd's 'The Essential Guide to Telecommunications' would be a good start for you. This book assumes a fair bit of knowledge on the part of the reader and is loaded with a lot of technical language, but if you are even a little comfortable with the telecom language, there's a great deal to be learned from this book.

Two things I really like about this book. First, the material is very up-to-date. In one chapter, Horak explains various 'flavors' of DSL very well--differences in how they are provisioned. He also spends a lot of time covering LAN and data networks, which is great considering most telecom traffic will eventually be data (not voice). Second, the diagrams showing how the networking equipment work and connect with each other is very helpful, especially for a guy like me with a non-engineering background.

I usually don't use the term 'gripping' to describe a technical book, but Horak's book is just that because I get hungry to learn more about how the whole telecommunications-network-thing works. Perfect to use in defense against those engineers who have looked down on the liberal arts grads for our ignorance of technology!

5.0 out of 5 stars Excellent knowledge baseline for communications networks, June 5, 2000

By 

Paul Given (Denver, CO - on the road) - See all my reviews

This review is from: Communications Systems and Networks (Paperback)

As a switch software developer for many years, I have developed a deep understanding of small corners of switch features, but lacked a good overall knowledge of network architecture. Thank you, Ray, for providing me with the system overview essential for the systems engineering job that I have recently assumed. This is a comprehensive overview of modern communications networks (with interesting brief histories - a nice touch for good readability) aimed at a person with some telecom experience, but like me, with an incomplete background. This book has very nicely filled in knowledge gaps with a great overview of the technologies involved in today's networks. Some of this was familiar, and the rest I knew only in vague generalities. I have been recommending it to others in the field as a good reference. My only complaint is that it is large and cumbersome, so does not travel well. A CD-ROM version would be a very nice handy reference while on my frequent road trips. And he takes his solicitation for input, as stated in the foreword, very seriously.

I think the level of detail is just right, as it gives me enough background to follow technical discussions and ask intelligent questions.

5.0 out of 5 stars Wow, An Instant Classic, July 9, 2000

When Ray sent me a copy of the new Second edition of "Communications Systems & Networks" I was expecting a good update of the 1996 first edition. Instead Ray has produced an almost entirely new text, and he's done a simply OUTSTANDING job.

Ray is the editor of Newton's Telecom Dictionary, and this book makes an excellent companion text to that great classic. Those of you who read my reviews know that I give free copies of that text to every student who attends my TrainingCity.com classes. If you bought Newton's Telecom Dictionary, buy this book, you won't ever regret it.

Ray uses his experience editing "Newton's" throughout "Communications Systems and Networks." Every term is explained clearly and concisely. Reading through this book I was continually amazed at how well Ray can explain complex concepts, and get ALL the relevant information into so few paragraphs.

In conclusion, I believe this is an instant classic, and a must have for any Voice & Data library.
