SS7 - The Quiet Revolution That Changed Your Telephone Service

Just about everyone is familiar with cellphones, smartphone apps, and ways to access social media while on the go. But what about the system that connects the world's telephone networks, and that makes seamless roaming and local number portability possible? The Internet? No, the enabling technology is Signaling System 7 - or SS7 - a signaling and control system that is both ubiquitous and virtually unknown to the public. SS7 has radically changed your life and the world that you live in, but most of the available information about SS7 was developed for telecommunication engineers and network executives. SS7 - The Quiet Revolution That Changed Your Telephone Service provides you and other readers with an overview of this fascinating system, how the underlying technologies developed, and how after four decades SS7 enables telecommunication networks to both function and evolve. Written for non-technical readers, this mini-book will be of interest to cellphone and Internet users, students, and adults who may be searching for a new career. This book received Honorable Mention in the Business/Technology category at the 2013 Great Northwest Book Festival.
