1.3 Applications for the Prestige 643
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 (e.g., 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.
