Definition
A signaling system 7 (SS7) gateway is an intelligent network (IN)–based system that can be used in conjunction with network-access servers (NASs) to offload the circuit-switched network congestion caused by dial-up Internet users. This system is also capable of creating new services for Internet service providers (ISPs).

Overview
This tutorial outlines the architecture necessary to employ SS7 technologies for Internet access and proposes the SS7 gateway as a potential solution for public switched telephone network (PSTN) overcrowding.
