1-2 What can the AR100 do for you?
not registered on the Internet, the AR100 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 AR100 allows small offices to communicate with other trading partners
using ISDN dial-on-demand or ISDN leased line. Information such as reports,
quotes and orders can be transferred between the two offices. The AR100 does
not place any limits on the number of network users, so it will continue to sup-
port you as your business grows.
Make phone and facsimile calls
The AR140 has two phone ports. Any combination of telephones, facsimile
machines, and answering machines can be connected to these two ports. Once
connected, they behave as if connected to a standard telephone network. Local,
national and international voice and facsimile calls can be placed and received
as normal. There is no need for a separate line for voice, facsimile and data—
one ISDN connection does it all. The two ISDN channels are shared between
data and voice as required. When both channels are being used for data, the
AR140 can be configured to bump one of these channels if a voice call is
required, for example when an emergency number is dialled.
The AR140 supports ISDN supplementary services, including call waiting, con-
ference calling, implicit call transfer and call forwarding. These services must
be provisioned on your ISDN line before they can be used by the AR140.
Note for Germany and Austria only: If you have leased lines on both ISDN B
channels, for instance one for an Internet connection and one for an inter-office
connection, you will not be able to connect telephones and use telephony serv-
ices even if you have an AR140 with phone ports.
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! This is not normally a problem as you
are just one of many millions of subscribers. However, the AR100 includes a
sophisticated packet filtering firewall that prevents unauthorised users access-
ing your local network, and ensures that only authorised users can access the
central office.
The AR100 also supports callback for outgoing calls. This allows a remote site
to reverse the call charges to a central office, for central billing of ISDN calls.
Make configuration simple
Your AR100 Series Internet Router has an easy to use web-based configuration
tool. A wizard leads you step by step through setting up an Internet connection
and/or an inter-office connection for the first time. If you want to add another
connection or change the configuration later on, you can do this easily from
your web browser.
