The NetVanta 344 is a business-class ADSL/ ADSL2/ADSL2+ IP access router with an integral four-port Ethernet switch. It

provides a single ADSL network interface and four auto-sensing 10/100Base-T Ethernet interfaces. This product is ideal for carrier bundled service offerings and enterprise Internet access for secure, high-speed corporate connectivity. In addition to supporting ADSL (Annex A and B), and ADSL2, the NetVanta 344 supports today’s most advanced ADSL technology, ADSL2+, for applications taking advantage of its greater reach and higher bandwidth, up

to 25 Mbps. A variety of WAN protocols are supported including PPP over ATM and PPPoE over ATM.

Standards Protocols

The versatile hardware platform of the NetVanta 344 is further complemented with the ADTRAN Operating System (AOS). The AOS allows for the support of standards- based switching, VLAN tagging, static and default routes, demand routing, and allows for fast, accurate network convergence using routing protocols such as BGP, OSPF, and RIP.

Security

The AOS provides a powerful, high perfor- mance stateful inspection firewall. It will examine all incoming and outgoing packets against the security policies established by the IT manager. In addition, the firewall can identify and protect against common Denial of Service (DoS) attacks like TCP syn flooding, IP spoofing, ICMP redirect, ping-of-death, and IP reassembly problems.

With the AOS Enhanced Feature Pack Upgrade, the NetVanta 344 supports up to five simultaneous IPSec VPN tunnels, and encryption algorithms like DES, 3DES, and AES. With this upgrade, the NetVanta 344 is fully compatible with other IPSec VPN equipped NetVanta products.

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 344 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 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.

Administration

The AOS offers a standard Command Line Interface (CLI) that mimics the widely adopted, industry de facto standard. The sequence of commands to configure similar devices is almost identical, virtually eliminating training costs associated with re-learning a new operating system or costly industry certifications. The CLI also allows for configuration scripts to be used, saved, and downloaded for a quick and easy recovery mechanism. In addition, an intuitive Web-based GUI provides step-by-step configuration wizards, management capability, and the ability to upload firmware updates.

ADTRAN, the leader in WAN connec- tivity, offers proven and dependable equipment that will increase your network performance, lower costs, and allow migration to next generation technologies. The NetVanta 344

is no exception.
