Introducing the AR745 Router
Congratulations on purchasing an AR745 Modular Branch
Office Router—A cost-effective, multi-service router platform
for larger branch office and corporate locations demanding high
data throughput, upgradeable connectivity and support for
multiple WAN services.
This guide will introduce you to the AR745 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 AR745
router, contact your local distributor or reseller.
CONNECTIVITY OPTIONS
The AR745 supports a wide range of network interfaces so
you can choose the network service that is right for you. High
speed routing is supported between the two built-in 10/100
Mbps Fast Ethernet ports. Hardware-based STAC/HiFn
compression and DES encryption maximize data throughput
without compromising routing performance.
The AR745 supports up to seven Port Interface Cards (PICs)
for flexible configuration. LAN and WAN PICs can be simply
and quickly field-upgraded as business needs change. PIC
connectivity options include E1/T1, Frame Relay, Primary Rate
and Basic Rate ISDN, leased circuits to 2Mbps, X.25, multiple
Ethernet and asynchronous serial for external modem dial-up.
WHAT CAN THE AR745 DO FOR YOU?
Connect You to the Internet
The AR745 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. The intelligent bandwidth
management facility automatically opens more ISDN channels
when extra capacity is required, and closes them when traffic
levels reduce. The AR745 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 Branch and Corporate Offices
High performance RISC-based technology ensures the high data
throughput demanded by data intensive and multimedia
applications. Powerful firewall features protect against
unauthorised access, and break-in attempts can be logged for
later analysis. If your office LAN uses private IP addresses not
registered on the Internet, the AR745 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 AR745 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 AR745 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 AR745 supports up to 26 dial-in connections via external
modems using the AR040 4-PIC NSM and six AR024 PICs.
Teleworkers and mobile users can dial into an AR745 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
also 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 AR745 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,
email or triggers. The firewall automatically detects and
combats a range of denial of service attacks including SYN
and FIN flooding, Ping of death, Smurf attacks and port scans.
•
IPsec-compliant security services.
•
Calling Line Identification (CLI), which uses the ISDN
address of the incoming call to verify that the caller is calling
from an authentic location.
