ADSL and DSL Technologies
An exploration of the standard that the author hopes will be the "next big thing" in Internet telephony. The author traces the history of the acronym-happy industry to its humble beginnings in the days when humans did the switching to show the evolution of the technology. Along the way he covers the architecture of the public switched telephone network (PSTN), digitizing the PSTN, ISDN, packet switching, the xDSL family of technologies, and HDSL 1 and 2. The second half of the book covers ASDL, DSLAM, VDSL, international issues and xDSL, and current issues in DSL. Appends information about the online ADSL Forum.

Know the difference between ADSL and DSL and the 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 of each variant with its advantages and disadvantages.
Much of the information in this book is about how the basic telephone system is structured 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 websites with information about ISPs. From there the Public Switched Telephone Network (PSTN) is covered well enough to use. Loops and Trunks are covered. There are 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 into the world of Circuit use and Packet Switching. MODEMs yep all kinds of 56K, Cable, MMDS, KMDS, and Satellite Systems. DSLs and T1s and so on and so on.
This book is packed with diagrams and statistics. Want to delve deeper than
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 these technologies at work and could not find any slip-ups.
