Release Notes for Cisco AS5300 Universal Access Servers for Cisco IOS Release 12.2 XA
78-12684-01 Rev. I0
Introduction
Introduction
The Cisco AS5300 is a versatile data communications platform that performs two functions in a single 
modular chassis, depending on the installed feature cards and IOS images:
Remote Access Server
Voice Gateway
The remote access server is intended for Internet service providers (ISPs), telecommunications carriers, 
and other service providers that offer managed Internet connections and medium to large sites that 
provide both digital and analog access to users on an enterprise network. By terminating both analog and 
digital calls on the same chassis simultaneously, the access server provides a clear, simple, and easy 
migration path from analog dial access services to digital dial access services.
The Cisco AS5300 Voice Gateway is a versatile data communications platform that provides the 
functions of an access server, router, and digital modem(s) in a single modular chassis. The 
Cisco AS5300 includes three feature card slots: one holds a T1/E1/PRI feature card, and the other two 
support modem feature cards or voice digital signal processor (DSP) feature cards. When equipped with 
modem cards, the Cisco AS5300 serves as a remote access concentrator for dial-up (modem or ISDN) 
Internet access. When equipped with voice feature cards and Voice IOS, the Cisco AS5300/Voice 
Gateway serves as a Voice over IP (VoIP) gateway. By using one slot for modems and the other for voice 
DSPs, the Cisco AS5300 can serve in both capacities. Modem, voice, or fax calls are routed to the 
appropriate cards/resources via Dialed Number Identification Service (DNIS).
