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 Number Portability and Number Pooling. The
document provides a history of regulatory decisions prompting the introduction of Number Portability and Number Pooling into U.S.
networks. It also describes the underlying components and technologies used to provide Service Provider Portability in domestic
wireline networks, and reviews issues and requirements development for Location Portability and some of the factors inhibiting its
deployment. The document also reviews other Number Portability technologies in use or proposed for use such as Wireless Number
Portability and international solutions. A description of the underlying components and technologies that will be used to provide
Thousand-Block Number Pooling in domestic wireline networks is included as well as future trends for Number Portability and Number
