Cisco Systems AS5200 manual Introduction, System Requirements, Memory Recommendations

Introduction

Introduction

The Cisco AS5200 universal access server is a multifaceted data communications platform that provides all the functions of an access server, a router, modems, and terminal adapters (TAs) in a modular chassis. Mid-sized organizations or service providers requiring centralized processing capabilities for mobile users and telecommuters will benefit the most using the Cisco AS5200 universal access server.

With its optimization for high-speed modem access, the Cisco AS5200 universal access server is ideally suited for all traditional dial-up applications, such as host access, electronic mail, file transfer, and dial-in access to a local area network.
