1.3 Applications
Here are some example uses for which the ZyXEL Device is well suited.
1.3.1 Internet Access
Your device is the ideal high-speed Internet access solution. It 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,
your device allows wireless clients access to your network resources and the Internet. A
typical Internet access application is shown below.

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 Making Calls via Internet Telephony Service Provider
In a home or small office environment, you can use your device to make and receive VoIP
telephone calls through an Internet Telephony Service Provider (ITSP).
