ADTRAN NetVanta 3305
Multi-slot Access Router Supporting up to Three T1s of Bandwidth

Overview:

The NetVanta^® 3000 Series of modular access routers is designed for cost-effective Internet access, corporate Frame Relay, point-topoint connectivity, ADSL, and Virtual Private Networking (VPN). The NetVanta 3000 Series currently consists of the NetVanta 3200, 3205, and 3305 with a variety of interchangeable NIMs and Dial Backup Modules (DIMs).

Modular Hardware

The NetVanta 3305 is a dual-slot, dual- Ethernet 1U high, rackmountable metal enclosure. A single slot within any of the NetVanta 3000 Series will house a variety of NIMs and DIMs. For dial backup, an analog modem DIM or an ISDN BRI DIM is available for preventing downtime by dialing around a failed circuit to any PPP-compliant device.

Standards Protocols

The versatile hardware platform of the NetVanta 3305 is further complemented with the ADTRAN® Operating System (AOS). The AOS allows for the support of static and default routes, demand and policy-based routing, and allows for fast, accurate network convergence using routing protocols such as BGP, OSPF, and RIP. In addition, the AOS terminates MPLS, Frame Relay, Multilink Frame Relay, PPP, Multilink PPP, PPPoE, PPPoA, RFC 1483, and HDLC Wide Area Network (WAN) protocols. Multihoming is also available to provide redundant or backup WAN links to multiple ISPs, guaranteeing a wide-area connection.

Quality of Service (QoS)

QoS is also supported for delay-sensitive traffic like VoIP or video. To prioritize mission-critical traffic and control network congestion, the NetVanta 3305 uses Low Latency Queuing, Weighted Fair Queuing (WFQ), Class-based WFQ, and DiffServ marking to establish priority of IP packets routed over the WAN.

VoIP Ready

In combination with the QoS features, a specialized Session Initiation Protocol (SIP) Application Layer Gateway (ALG) allows SIP traffic to traverse NAT-enabled firewalls. For an enterprise network, this interoperability allows IP PBXs, phones, and other SIP-based devices to set up, tear down, and pass voice and call control messages seamlessly through the integral NAT-enabled firewall.

Security

For added security, AOS provides a powerful, high-performance stateful inspection firewall that can identify and protect against common Denial of Service (DoS) attacks like TCP syn flooding, IP spoofing, ICMP redirect, ping-ofdeath, and IP reassembly problems.

In addition, the AOS is capable of providing an inherent URL-filtering package without the use of an external server. URL filtering is another level of security that allows system administrators to restrict Internet access by permitting or denying specific URLs. This URL-filtering feature also includes the ability to produce top website reports of the most frequently requested websites, allowing system administrators to modify the URL filter lists.

The NetVanta 3305 also supports up to 500 simultaneous VPN tunnels, while supporting encryption algorithms like DES, 3DES, and AES. By supporting IPSec, the NetVanta 3305 is fully compatible with other IPSec VPNequipped NetVanta products.

Administration

The AOS offers both a CLI that mimics the widely deployed, industry de facto standard and an intuitive Web-based GUI with step-bystep configuration wizards.
