2 Introduction to SS7

Purpose

This chapter will familiarize you with Signaling System 7 (SS7) and the operation of the SS7 network. This chapter describes the CSP implementation of SS7 and provides concepts and information necessary to use the SS7 PQ and SS7 Series 3 cards. For a list of the common acronyms used in SS7, see the Appendix of this book.

The SS7 PQ and SS7 Series 3 cards provide Signaling System 7 connectivity for CSPs, and also provides a fully integrated solution for both switching and advanced signaling applications.

In this guide, where reference is made to "SS7 cards", the reference is for both the SS7 PQ card and the SS7 Series 3 card.
