1-2 Adit 3500 - Release 1.6

Adit 3500 Base Platform

Overview

The Adit 3500 integrates the features of a trunk gateway, highperformance IPSec VPN-capable router,

and stateful firewall with flexible WAN options. It replaces multiple elements at the customer premises

that typically provide routing, security, and trunk gateway functions – offering a powerful blend of

speed, security, data and voice. Additionally a 4 FXS option provides connectivity for analog fax and

modems. This single platform offers scalability and high-performance for Internet and IP access, LAN-

to-LAN connectivity over private and public networks, and VoIP PBX trunk service applications.

Converged IP Services without Sacrificing Performance

Unlike competing offerings, the Adit 3500 maintains 2xT1 wire-speed throughput with low latency for

all packet sizes. The Adit 3500’s VoIP-aware routing engine is based on advanced network processing

technology and enables converged IP applications without the typical degradation in performance seen

in other legacy solutions on the market. By integrating routing and security features into a single

processor, the Adit 3500 cost-effectively supports Network Address Translation (NAT/NAPT), stateful

packet inspection, flow classification, Application Layer Gateway (ALG), intrusion detection and

IPSec VPN tunneling. Access control lists also protect traffic flowing in and out of the network. The

integrated firewall keeps the network and LAN segments secure from intrusions and attacks while

allowing authorized access to network resources.
