Demystifying ISDN

Rating:
Summary: Introductory
Review: A basic introductory text. Geared towards users of ISDN as a help text on installation and purchase. You'll get some understand of the technology behind ISDN but not much. The book itself says it is of an "introductory" level and I have to agree. This book won't serve as a reference book.

Buy it, read it, toss it. Don't buy it if you already know something about ISDN.

Review: If you are clueless about ISDN the way I was before I read this book then this text will be very usefull to you! This book will help you lay the foundation of knowledge necessary to understanding ISDN.
