1.2.1 Internet Access
The ZyXEL Device is the ideal high-speed Internet access solution. Your ZyXEL Device
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.
