Cisco Cisco IOS Software Release 12.2(27)SBC テクニカルリファレンス

This document uses model networks tested in a Cisco lab to describe how to deploy a service provider 
broadband-based network using Cisco 7200, 7300, or 10000 routers as a Cisco Intelligent Service 
Gateway (ISG) and ATM as the aggregation technology. The Cisco ISG software provides a feature set 
that assists the service provider with provisioning and maintaining broadband networks that have many 
types of edge devices and many subscribers and services. The Cisco ISG software combines real-time 
session and flow control with programmable, dynamic policy control to deliver flexible and scalable 
subscriber session management capabilities. The role of the Cisco ISG software is to execute policies 
that identify and authenticate subscribers, and to provide access to the services that the subscriber is 
entitled to access. The role of the Cisco ISG router is deployment at network access control points so 
subscribers can access services through the software.

Cisco IOS software is packaged in feature sets that are supported on specific platforms. The Cisco ISG 
software is supported on Cisco 7200, 7300, and 10000 series routers. To get updated information
