Well, I am not going to tell you that other books about ADSL are not good. Usually if you buy a book dealing with ADSL, you want to see the practical and the theoretical aspect. Sometimes, you would like to know what is the mathematical base of ADSL. This book deals the practical, theoretical and mathematical concept of ADSL in great detail.

The author has a good and precise approach. However, it seems to me that, as an active member of some organizations relating to the field, the author had opportunities to look at some paper works, he "cut and paste" without verifications ?!? I read up to Chapter 4 and found too many errors. I found the matrix in Ed 2.28 was wrong, Eq 2.60 mus have derivative operator in LHS, ..., but the result in Eq 2.41 ~ 2.50 were correct ! Eq.3.16 is correct, but its development is not precise (messy). I failed to prove Eq 4.23 and its consequences are correct !

Fast, faster, fastest - up to 30 meg. That's the promise of DSL, and this book explains how it works, what it requires, and the technical problems to be overcome.

It is a very good book. However, I got a couple of questions and I need to contact the author. Would someone please tell me how to contact him? Thank you very much.
