32 Chapter 1 Getting To Know Your ZyXEL Device
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.

Internet Single User Account
For a SOHO (Small Office/Home Office) environment, your ZyXEL Device 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.
1.2.2 LAN to LAN Application
You can use the ZyXEL Device to connect two geographically dispersed networks over the
ADSL line. A typical LAN-to-LAN application for your ZyXEL Device is shown as follows.
