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. 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.
