Getting To Know Your Prestige 1-7
1.3 Applications for the Prestige
Here are some example uses for which the Prestige is well suited.
1.3.1 Internet Access
The Prestige is the ideal high-speed Internet access solution. Your Prestige supports the TCP/IP protocol,
which the Internet uses exclusively. It is compatible with all major ADSL DSLAM (Digital Subscriber Line
Access Multiplexer) providers. A DSLAM is a rack of ADSL line cards with data multiplexed into a
backbone network interface/connection (for example, T1, OC3, DS3, ATM or Frame Relay). Think of it as
the equivalent of a modem rack for ADSL. In addition, for the Prestige 652H/HW, you can insert an optional
wireless PCMICA card into the Prestige and allow wireless clients access to your network resources. A
typical Internet access application is shown below.

Internet Single User Account
For a SOHO (Small Office/Home Office) environment, your Prestige offers the Single User Account (SUA)
feature that allows multiple users on the LAN (Local Area Network) to access the Internet concurrently for
the cost of a single IP address.
1.3.2 Firewall for Secure Broadband Internet Access
The Prestige provides protection from attacks by Internet hackers. By default, the firewall blocks all
incoming traffic from the WAN. The firewall supports TCP/UDP inspection and DoS (Denial of Services)
detection and prevention, as well as real time alerts, reports and logs.
