5.0 out of 5 stars Everything you need to know about communications, March 26, 2000

This review is from: Digital Telephony (Wiley Series in Telecommunications and Signal Processing) (Hardcover)

I teach communications concepts and have found this book to be the single most valuable book in my pursuit of knowledge. Every subject I've needed more information on is covered. Most subjects are explained with a good understanding of communications and concepts assumed by the author...a strong math background would also be helpful. All in all I have yet to find a better all around book that encompasses the communications field as well as Digital Telephony does.

5.0 out of 5 stars The bible of the telephone network, August 6, 2000

By A Customer

This review is from: Digital Telephony (Wiley Series in Telecommunications and Signal Processing) (Hardcover)

I must admit up front that I'm a long time fan of Dr. Bellamy's book "Digital Telephony" having extensively used the second edition. That edition still sits on my shelf, filled with yellow highlights and stick-on tabs with notes indicating certain areas of the book. I had reviewed that edition with praise, only mentioning that the book needed an update. When the third edition was released, I immediately bought a copy.

There just isn't another book (at least none I've found) that explains how the telephone network "works". The book covers everything, from speech coding, to modulation, to switching, and more. If your work requires that you have an understanding of the network, this is the book for you.

The third edition continues to provide this broad view of the public network, adding or expanding coverage of newer areas such as ATM and optical communications.

I highly recommend this book to all communications engineers and network professionals.

5.0 out of 5 stars The bible of how the digital telephone network works, July 31, 1998

By A Customer

This review is from: Digital Telephony (Wiley Series in Telecommunications and Signal Processing) (Hardcover)

Dr. Bellamy's book covers almost all aspects of how the digital telephone network works, including voice processing, codecs, switching, and traffic analysis. I don't know any other book that focuses on the public telephone network like this one. Personally, I've learned a great deal from this book - my copy is dog-eared with lots of notes and yellow highlights. Whenever I need to know something about the network, this is the first place I turn to. The only shortcoming of the book is its age (published 1991). There is no coverage of voice over IP or voice over ATM, for example. Perhaps Dr. Bellamy will do a third edition soon. Please note that this book is not intended for a lay audience. It assumes a level of knowledge equivalent to an electrical engineering degree. All in all, an excellent text which can be used for learning and for reference.
