Introducing the AR720 Router
Congratulations on purchasing an AR720 Modular Network
Access Router—the optimal solution for larger branch and
corporate sites with demanding network requirements.
This guide will introduce you to the AR720 router and guide
you through the most common uses and applications. Getting
started will not take long—many applications can be set up in
just a few minutes. If you have any questions about the AR720
router, contact your local distributor or reseller.
CONNECTIVITY OPTIONS
The AR720 supports a wide range of network interfaces so
you can choose the network service that is right for you. The
base unit has one 10/100 Fast Ethernet port and two RJ45
asynchronous ports. Additional interfaces can be added by
installing any of the following PICs (
Port Interface Cards
) in the
two expansion bays:

WHAT CAN THE AR720 DO FOR YOU?
Connect You to the Internet
The AR720 router provides you with high speed, unrestricted
access to the Internet. Advanced compression techniques
together with ISDN channel bundling mean that graphic
downloads simply speed along. An intelligent traffic sensor
automatically disconnects the ISDN call if there is no data to be
sent or received, so call charges are minimised. The AR720
supports advanced features that make it easy for your Internet
Service Provider to dynamically assign your Internet address
every time you surf the net.
Connect Regional and Branch Offices to the Corporate
Network
Many small offices and home offices require fast and efficient
access to a central office, to check email, access a database or
download a file. The AR720 supports Windows
®
, Novell
®
and
Apple
®
Macintosh
®
systems. The intelligent bandwidth
management facility automatically opens more ISDN channels
when extra capacity is required, and closes them when traffic
levels reduce. Powerful firewall features protect against
unauthorised access, and break-in attempts can be logged for
later analysis. If your office LAN utilises private IP addresses not
registered on the Internet, the AR720 can translate these private
addresses to a single registered IP address for communication
across the Internet, saving you the time and expense of assigning
registered IP addresses to each device on your LAN.
Connect You to Other Trading Partners
The AR720 allows companies to communicate with other
trading partners using ISDN, leased line, Frame Relay or X.25
services. Information such as reports, quotes and orders can be
transferred between the two offices. The AR720 does not place
any limits on the number of network users, so it will continue
to support you as your business grows.
Connect Teleworkers and Dial-in Users
The AR720 supports dial-in connections via external modems.
Teleworkers and mobile users can dial into an AR720 router at
their local office and access information, read email, download
files and connect to the Internet. Combine dial-in services with
AT-VPNet to provide teleworkers and mobile users with
secure access to the corporate network. External modems can
be used to provide network connections for extra bandwidth
at peak times or to backup ISDN, Frame Relay or leased lines.
Protect Your Network from Unauthorised Access
When you connect to the Internet you have unrestricted
access to the World-Wide Web. Likewise, it has access to you!
To ensure that only authorised users can access your local
network, the AR720 has an extensive range of security
measures, including:
•
A fully featured stateful inspection firewall which dynamically
filters traffic flows based on manager-defined rules. All
firewall events are logged to the router’s Logging Facility, and
significant events generate notifications via SNMP traps,
