The NetVanta®3000 Series of modular access
routers is designed for cost-effective Internet
access, corporate Frame Relay, point-to-point
connectivity, ADSL, and VPN. The NetVanta
3000 Series currently consists of the NetVanta
3200, 3205, and 3305 with a variety of inter-
changeable NIMs and DIMs.
Modular Hardware
The NetVanta 3205 is a single-slot, single-
Ethernet 1U high, rackmountable metal
enclosure. A single slot within any of the
NetVanta 3000 Series will house a variety
of NIMs and DIMs, which include a 56/64k,
T1/FT1, T1/FT1 with DSX-1, Dual T1s, E1/FE1,
E1/FE1 with G.703, ADSL, SHDSL, or a Serial
interface. 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 3205 is further complemented
with the AOS. The AOS allows for the support of
static and default routes, demand routing, and
allows for fast, accurate network convergence
using routing protocols such as BGP, OSPF, and
RIP. In addition, the AOS terminates Frame
Relay, Multilink Frame Relay, PPP, Multilink PPP,
and HDLC Wide Area Network (WAN) protocols.
Multihoming is also available to provide redun-
dant or backup WAN links to multiple ISPs,
guaranteeing a wide-area connection.
Security
For added security, The AOS provides a
powerful, high-performance stateful inspec-
tion 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 3000 Series adds the support
for IPSec-compliant VPN. The NetVanta 3205
supports up to five simultaneous VPN tunnels,
while supporting encryption algorithms like DES,
3DES, and AES. With this upgrade, the NetVanta
3205 is fully compatible with other IPSec VPN-
equipped NetVanta products.
QoS
QoS is also supported for delay-sensitive traffic
like VoIP or video. To prioritize mission-critical
traffic and control network congestion, the
NetVanta 3205 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.
Administration
AOS offers a standard CLI that mimics the
widely adopted, industry de facto standard. The
sequence of commands required to configure
similar devices is almost identical, eliminating
training costs typically associated with learning
a new operating system or obtaining 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 connectivity,
offers reliable equipment that increases
network performance, lowers cost, and
positions networks for the future. In
addition, these products are backed by an
industry-leading five-year North American
warranty, free firmware downloads, and
world-class technical support from ADTRAN.
