Cisco Cisco IOS Software Release 12.2(27)SBC Références techniques

Intelligent Service Gateway (ISG) is a Cisco IOS software feature set that provides a structured 
framework in which edge devices can deliver flexible and scalable services to subscribers. This 
document provides information and procedures to migrate broadband components from the 
Cisco Service Selection Gateway (SSG)—a Cisco IOS software feature set that works with the 
Cisco Subscriber Edge Services Manager (SESM) and other components to provide a subscriber edge 
services solution—to the Cisco Intelligent Service Selection Gateway (ISG) and updated SESM feature 
software.

This document is intended for network engineers migrating an SSG-based deployment to an ISG-based 
one. It is expected that the user of this document is knowledgeable about Cisco IOS and SSG software.

For this phase of SSG-to-ISG migration, only digital subscriber line (DSL) network migration has been 
tested and is supported. Migrating deployments such as wireless LAN (WLAN) and general packet radio 
service (GPRS) will be described at a later time in separate documents.
