Customer Reviews

Know the difference in ADSL and DSL and them others
This book takes you from ground zero to explain how the many protocols and technologies work. There are plenty of diagrams with extensive explanations on each variant with their advantages and disadvantages.
Much of the information in this book is how the basic telephone system is structures and can apply to many areas besides DSL.

There is way too much detail to scratch the surface with this review so I will just cover some of the highlights.

He covers the emergence of the internet and web sites with information about ISP’s. From there the Public Switched Telephone Network (PSTN) is covered well enough to actually use. Loops and Trunks are covered. This is the mystery boxes in the phone room at work. The differences between analog and digital trunks are described. ISDN and DAML are covered along with the “Law of Large Numbers”. Alright now he moves in to the world of Circuit use and Packet Switching. MODEMs yep all kinds 56K, Cable, MMDS, KMDS, and Satellite Systems. DSL’s and T1’s and so on and so on.

This book is packed with diagrams and statistics. Want to delve deeper then
Appendix A Case studies
Appendix B Sources of Standards and Specification Information

Don’t ask me how all this can be packed in one book but it is and I use most of this technologies at work and could not find any slipups.

Excellent ADSL reference but hugely US centric
For anyone starting into ADSL or wanting to find out a bit more then this is an excellent book providing a complete overview starting from the basics. The book is well laid out and takes the reader through all associated technologies in a clear and easy to follow fashion but still providing the necessary technical depth.

The main problem however is that it is all based on the US system with only the final chapter paying some attention to the Rest of the World. Here, some of the differences are mentioned including pointing out that US uses a National standard which is different to the International standards used elsewhere but without being specific on the differences or which Non-US standards to reference.

Overall however an excellent book to learn everything from the early history through to the latest implementations.

Well written primer
The book is well written (by computer book standards :) ), and offers a surprising amount of information about the current US phone system (europeans, africans, etc. are out of luck....). It would have been interesting if there had been information about say Covad, Cisco and others who are actually implementing these technologies.
