Model 3120 Remote Access Server overview
The Model 3120 is a central site remote access server with integrated modems which terminate dial-up analog
and digital users. The Model 3120 RAS combines 96 or 120 analog and digital modems, RAS software, two
10/100 Ethernet ports, IP Routing, Frame Relay/PPP forwarding, and four T1/E1 WAN ports.
The 3120 RAS simultaneously consolidates analog modem and digital ISDN remote access connections (over
PSTN digital trunks) using a completely digital approach. Up to four T1/E1/PRI ports provide PSTN and/or
PABX connectivity and terminate up to 96/120 analog modem or digital ISDN calls within a single chassis.
The Model 3120 incorporates channel bank, terminal server, router and modem functionality in a self-con-
tained, compact package.
