The Barnes & Noble Review
Softswitches are the wave of the telecommunications industry's future! If you want to know more, you should read this excellent book on softswitch technology as the enabling platform for next-generation packet communications -- including voice, broadband, and wireless networks. Franklin D. Ohrtman does an outstanding job of showing how softswitch technology and applications enable global service providers and carriers to optimize their networks and generate new revenue streams with new services and applications. In other words, the author illustrates how softswitch technology disrupts incumbent service providers and their vendors. He helps to identify some of the success and technological challenges of the industry based on the softswitch.

This book focuses on the metrics of performance of the emerging telecommunications infrastructure in terms of scalability, reliability, quality of service (QoS), signaling, and features. Ohrtman analyzes how softswitch technologies might meet or exceed the performance parameters of the Public Switched Telephone Network (PSTN) infrastructure (specifically Class 4 and 5 switches, in addition to Private Branch Exchanges (PBXs). He also explains how it's becoming increasingly clear that Creative Destruction takes place from an engineering perspective. The addition of an acronym list is also a nice touch.

The telecommunications industry is changing, and opportunities abound. Folks who find themselves caught up in this revolution will be delighted with this well-written and coherent account of what's changing and why. Not incidentally, they will also learn how to benefit from these changes. John Vacca

Meet the Author

Frank Ohrtman has many years experience in sales of VoIP and softswitch platforms. His career in VoIP began with selling VoIP gateway switches for Netrix Corporation to long distance bypass carriers. He went on to promote softswitch solutions for Lucent Technologies (Qwest Account Manager) and Vsys (Western Region Sales Manager). The genesis of this book lies in answering customer objections to VoIP and, tangentially, softswitch technologies.

Mr. Ohrtman learned to perform in-depth research and write succinct analyses during his years as a Navy Intelligence Officer (1981-1991). He is a veteran of U.S. Navy actions in Lebanon (awarded Navy Expeditionary Medal), Grenada, Libya (awarded Joint Service Commendation Medal) and the Gulf War (awarded National Defense Service Medal). Mr. Ohrtman holds a Master of Science degree in Telecommunications from Colorado University College of Engineering (master's thesis: "Softswitch As Class 4 Replacement--A Disruptive Technology") and a Master of Arts degree in International Relations from Boston University.

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.
