ABSTRACT: Technology - Webster's New Collegiate Dictionary defines it as a "technical method of achieving a practical purpose." A concise, clear
definition. But for many, achieving that practical purpose can be more than just a challenge. It can be frustrating, intimidating,
time-consuming, and bound to generate the question, "Where Do I Start?"
With the Telcordia Notes On.... series, Telcordia Technologies has devised a starting point for your search through the rapidly
developing world of telecommunications. Written by the authors of the successful Notes On the Networks document SR-2275, this
series similarly contains technical material of interest to engineering and planning groups, as well as descriptions of the
characteristics and background of these subjects in layman's terms. The difference is that Telcordia Notes On.... zeroes in on one
technology in each document and breaks it down into manageable terms. From the history, background, and basic elements through a
discussion of what the future may bring, our subject matter experts cover the important aspects in as few words as possible.
This Special Report in the Telcordia Notes On....series takes an in-depth look at the evolution of 9-1-1 Service and alternative
E9-1-1Service architectures that are available to provide enhanced Emergency Services to wireline and wireless callers. Learn about the
history of 9-1-1 service, its current operation, and the evolution of E9-1-1 networks in response to technology changes.
You will learn about: the history of 9-1-1 Service; the current 9-1-1 network architectures; wireless and 9-1-1 (discusses location
technologies and issues); and the evolution of the E9-1-1 network (examines an AIN-based E9-1-1 service architecture and a Next
Generation Network E9-1-1 service architecture). Over 20 detailed diagrams that depict routing architectures for wireline and wireless
service guide you through the learning process.
Also, an extensive Definition of Terms in Section 1 lays the groundwork for the remainder of the document, and the Bibliography
contains references for both standards documents and further reading material from Telcordia.
