Adtran 3430 Specification Guide

The NetVanta

3430 is a modular access

router that uses RapidRoute technology to
deliver the high-packet throughput required
for IP telephony, corporate connectivity, and
Internet access. This performance-enhanced
platform delivers wire-speed throughput, even
with advanced services enabled like Quality of
Service (QoS), NAT, firewall, and VPN.

Modular Hardware
The NetVanta 3430 is a modular, 1U-high,
rackmountable metal chassis that offers two
10/100Base-T Ethernet interfaces for WAN
access LAN segmentation, DMZ, or even
broadband backup. The single slot houses
any of the NetVanta Series Network Interface
Modules (NIMs) and Dial Backup Interface
Modules (DIMs). For dial backup, an analog
modem DIM or an ISDN BRI DIM is avail

able, preventing downtime by dialing around a
failed circuit to any PPP-compliant device.

Standards Protocols
Complementing the versatile hardware,

the AOS allows for the support of standards-
based switching, Virtual LAN (VLAN) tagging,
static and default routes, and demand routing.
This enables fast, accurate network conver

gence using routing protocols such as BGP,
OSPF, and RIP. In addition, the AOS terminates
MPLS, Frame Relay, Multilink Frame Relay,
PPP, Multilink PPP, 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.

QoS
QoS is also supported for delay-sensitive traffic
like VoIP or video. To prioritize mission-critical
traffic and control network congestion, the
NetVanta 3430 uses Low Latency Queuing,
Weighted Fair Queuing (WFQ), Class-based
WFQ, and DiffServ marking to establish the
priority of IP packets routed over the WAN.

Modular Access Router

VoIP Ready
In combination with the QoS features, a
specialized SIP ALG allows SIP traffic to
traverse NAT-enabled firewalls. For enterprise
networks, 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.

The NetVanta 3430 also deploys VQM to

capture MOS, jitter, delay, and packet loss
statistics necessary to troubleshoot VoIP calls
over the WAN. This powerful, yet graphically
intuitive, diagnostic tool allows for quick
isolation of network issues to ensure

superior call quality.

Security
The AOS provides a powerful, high perfor

mance stateful inspection firewall that 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.

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 3430 also supports up to 500

simultaneous IPSec VPN tunnels and encryp

tion algorithms like DES, 3DES, and AES. By
supporting IPSec, the NetVanta 3430 is fully
compatible with other IPSec VPN-equipped
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-

by-step configuration wizards.
