Summary: t/e carrier book
Review: This book decribes quite good the T1/E1 subject. However the T3 section is very limited, and the E3 is not mention.

Summary: ...
Review: This book is intended to focus on a digital transmission discussion. For any digital transmission discussion (either high speed or low speed), one of the most important issue is sychronization. I see this sychronization as blood flow in human body, controlled by heart (clock source). Sychronization is so important that every digital transmission discussion would be meaningless without discussing it. Since this book is intended as a preliminary to more advanced broadband topics, I think sychronization dicussion rewards at least one special chapter in this book.
I found sychronization discussion in this book was little. The author only described clocking, timing, and synchronization as sub chapter with little discussion of slip, jitter, and wander concept. For beginner to try to understand sychronization as fundamental of broadband telecommunications, the discussion was not deep enough. I found sychroniztion discussion in "Engineering Networks for Sychronization, CCS 7, and ISDN" by P. K. Bhatnagar would be more informative for beginner than this book.
I also found that almost every time the author was derailed in presenting the T/E carrier itself. I think this book should focus extensively on T/E carrier and not other topics. Instead the author "confused" readers (especially beginners) with mixing ISDN, SONET, and SDH into discussion. I think the author should discuss synchronization and t/e carrier deeper first in at least (maybe) 7 chapters before entering discussion of ISDN, SONET, SDH, and other more advanced broadband telecommunications; in order not to confuse beginner readers.
I think the only "real discussion" in this book are chapter 6, 7, and 9. This three chapters are focused on the heart of t/e carrier itself. I think the author did a quite good job in the explaining. I think only these three chapters makes this book a quite worthwhile (and deserves 3-star rate rather than 2).
<(...)BR>I think this book would be more suitable for professionals who already have tastes of t/e carrier rather than beginners. If this book has more coverages, it would be a great book for both experiences and beginners. I expect the third edition (if would be any) would become more extensive and have more coverages.

Summary: Good description of Sonet and SDH
Review: This book is interresting for those who are beginning to work with SDH or Sonet Networks and includes a part on synchronization. It is a practical book who does not go too much theoretically in complicated concepts.
