1.1.2.1 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, the Prestige allows 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.

1.1.3 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.
