3.0 out of 5 stars
A good intro to ATM & DSL, but be careful of the details.,
By A Customer
This review is from: Demystifying ATM/ADSL (Paperback)
Technical books that attempt to be more than a pure reference manual (i.e. a schematic or specification) can be the most difficult endeavors to write. Finding truly great technical books are rare. Therefore, when I say that Demystifying ATM/DSL is only fair, I am saying it is as good as most.The book is a good start to understanding how ATM and DSL may come together and why they are a good solution in the market. Unfortunately, the writer wants the book to be both a technical reference and an overview at the same time. As a result, he fails to do either really well. On the technical reference side of the coin, the book takes you all the way to the altar, but does not marry you. In lynchpin areas of discussion, you get just enough detail to leave you wondering about the rest of the story. For example, in trying to find out about the direct relationship between AAL types, and QoS in ATM, there is one sentence that states CBR uses either AAL1 or 5 (page 131). No other reference is made to the relationships between the others leaving you to wonder what, if any, these relationships are. Another problem with the technical information is that the casual or novice reader may not notice the errors leaving them either confused or completely misled. For example, the author uses the term microsecond in one sentence and then abbreviates it with "msec" (which stands for millisecond) (page 201). Which amount of time the author meant, I still do not know. In another example, the author mixes up the headers on a table reversing the ITU and ATM forum (page 131). If the headers are not reversed, then the table on the previous page must be wrong. I am concerned about other errors I simply absorbed due to their subtlety. As an overview of ATM and DSL, the book covers a good swath of both the technical and the market. Opinions are clearly unidentified by either direct reference, or intonation. If the reader is careful about the aforementioned technical content, a good foundation of understanding can be ascertained from the book. Again, I do give the book a solid three stars because these types of books are so difficult to write (as proven by the field available). The problems in the text are not unusual to technical books at large.

This is not a technical book,
By
This review is from: Demystifying ATM/ADSL (Paperback)
I bought the book searching for technical material that would help me understand the ATM/ADSL protocols.What I found was an extremely superficial book that explains the very basics of telecommunications, digital transmission and the OSI layers. With 1 very short and practically irrelevant chapter reserved to ATM itself and another to ADSL, I wouldn't recommend anyone this book. If you're the extreme beginner, search for a primer on networking or telecommunications. If you're not, get another book on ATM.

A Great Read,
By A Customer
This review is from: Demystifying ATM/ADSL (Paperback)
Mr. Busby explains ATM and DSL in easy to understand terms. For the non-engineer, this book is a god-send. Additionally, the book is written with a certain humorous style that makes the otherwise dry technical information easy to digest. I think it is a great read and recommend it to anyone wanting or needing to understand these two technologies.
