Following robust sales of its first edition, this best-selling guide is updated and expanded to serve the exploding telecommunications market. Focusing on SS7-the series of protocols that form the underlying basis of all telecommunications networks-it explains the new international Telecom Union (ITU) standards issued by the global telecom authority; new broadband standards; and major new SS7 issues such as local number portability, a sought-after feature that permits people and businesses to keep the same phone number even if they move.

From the Back Cover

The only complete guide to SS7-revised and updated. Don't rely on ANSI publications or Bellcore standards to learn SS7 from the inside out. Turn instead to this bestselling guide, now fully updated to reflect the latest changes in the SS7 signaling network and its cellular, broadband, and international applications. Inside you'll discover: a complete "short course" on SS7, its architecture, and protocols; specific technical data for design and specifications; ramifications of SS7 changes following the Telecommunications Act of 1996; practical analysis of Bellcore GR-246-CORE and other key specs; full coverage of the latest ITU standards for global SS7 use; insights into revised broadband ISUP protocols and procedures; an overview and explanation of local number portability (LNP) based on the SS7 protocols, which has been mandated by the FCC for deployment by telcos and wireless providers by 1999. Packed with real-world examples and applications, this hands-on guide is for everyone who works with SS7. Novices will find it readable and informative... engineers designing new products will embrace it as a useful reference and a refreshing break from the monotonous specifications used throughout the industry... and professionals in the field will find it such an invalulable working tool that they may even want to offer it to their customers.
