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 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 iden-
tify 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 encryp-
tion 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 conges-
tion, 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 elimi-
nating 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 config-
uration wizards, management capability, and
the ability to upload firmware updates.
ADTRAN, the leader in WAN connectivity,
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.
