ADSL Business Class
Routing Solution

The AT-AR441S is a competitively priced,
business-class, secure ADSL router. This desktop,
broadband router allows businesses to take
advantage of cost effective DSL connections
without compromising on bandwidth,
throughput, features, or security.

The AT-AR441S has been designed with the
needs of the branch office or small to medium
business in mind and comes with dying gasp and
the WAN back-up features businesses expect.

The AT-AR441S comes with, or has as optional
extras, all the software features necessar y for a
product of this type, such as:

•

An extensive VPN capability

•

Comprehensive ADSL suppor t

•

An extensive QoS suite

•

Multiple routing protocols

•

A comprehensive configuration and
management suite

Extensive VPN Capability

The AT-AR441S provides extensive IPsec based
VPN capability, allowing the interconnection of
branch offices, remote tele-workers, and other
users who require secure access to a corporate
network. This capability provides a cost effective
alternative to long-distance dial-in, leased line or
frame-relay connections. The AT-AR441S comes
complete with integrated hardware acceleration
to maximise encr yption and throughput during
secure communication. The product is compatible
with industr y standard IPsec VPN clients.

Security

In addition to hardware-based encr yption, the
AT-AR441S comes with other security features,
such as traffic filtering with event logging. Traffic
filtering uses the source and destination address,
por t, protocol and TCP packet type to provide
control over traffic that passes through the
AT-AR441S. The AT-AR441S' Stateful Inspection
firewall provides an increased level of security,
and HTTP and SMTP proxies provide improved
control over web and mail communication.

Software Quality of Service

The AlliedWare

TM

operating system provides

advanced Quality of Ser vice (QoS) and traffic
shaping features. There are five key QoS features
available on the AT-AR441S:

•

Bandwidth Metering

•

RED Cur ves

•

Mixed Scheduling

•

Vir tual Bandwidth

•

Dynamic Application Recognition (DAR)

Software QoS also suppor ts eight queues per
interface. DAR is used to snoop for session
setup exchanges and dynamically create
classifiers that match the voice and video
packets in the session. For more information,
see the Allied Telesis Advanced QoS White
Paper available on our website.

Flexibility of Modular Routing

A Por t Interface Card (PIC) por t on the
AT-AR441S provides businesses with a high
degree of flexibility, enabling them to future proof
their investment, obtain additional functionality or
make use of WAN back-up options. For
example, a backup WAN card, such as an ISDN
card, can be installed in the PIC por t enabling
businesses to protect themselves against ADSL
downtime. The PIC options available also enable
businesses to achieve a higher LAN density
without purchasing an additional switch. The
AT-AR441S PIC por t is compatible with a range
