Title: Softswitch : Architecture for VoIP (Professional Telecom) by Frank Ohrtman ISBN: 0-07-140977-7 Publisher: McGraw-Hill Professional Pub. Date: 10 December, 2002 Format: Paperback Volumes: 1 List Price(USD): $49.95 |
Average Customer Rating: 4.25 (4 reviews)
Rating: 2
Summary: Not a good value
Comment: Mr. Ohrtman spends much of the book to argue his case for VOIP rather than discussions of how it works and how it interfaces with the PSTN. The technical discussions, especially for the local loop alternatives, were very basic and not of much value.
Rating: 5
Summary: This book pulls no analytical punches...
Comment: This is the book that traditional switchmakers like AT&T, Nortel, Ericsson, Siemens and Alcatel and LECs like Verizon and QWest don't want you to read. Softswitch poses a highly disruptive threat to telecom monopolies. This book pulls no analytical punches in pointing out how the array of softswitch technologies (Class 4 and 5 replacement, IP Centrex, and IP-PBX) provide a lower barrier to entry to the service provider market and how this technology saves existing service providers in terms of OAM&P. If legacy telephone companies want to survive into the next decade, they must learn the lessons contained in this book.
Rating: 5
Summary: A very effective introduction
Comment: Finally a book from a known publishing house about softswitch. The book is about the definition, need and scope of the softswitch from both a technical and economic perspective. The piece dealing with the current trend and the future market is particularly well written. Highly recommended to the newbies as well as to the know-it-all folks of softswitch world.
