Walter GoralskiRezensionen

This is not an easy read. Then again, if you're using SONET, you aren't looking for a bedtime story. I see (on Amazon) there's a third edition out, and if you're looking at this book, you should get that one instead.

The discussion of SDH in this book is invaluable, but it's changed from 2000 (which is when this was published), and you should be looking at the newer book (ISBN 0072225246) if SONET is part of your workday. Even the update was published in 2002, and the reviews for his current book are mixed.

I appreciated it when I was working, but there are errors (and they apparently didn't get fixed with the 3rd Edition).

Interesting to read all the reviews on Amazon.½

Absolutely not recommended.
A perfect example of why the telcos have nothing useful to contribute to the world of technology.

This book is long paean to the joys of circuit switching, with barely a nod to the realities of the internet, and written in 1998 for god's sake.
I was hoping that there'd be something about the signal processing inherent in getting DSL to work, but none of that.½
