Router Description and Operation
The DSL-522T Router is designed to provide a simple and cost-effective ADSL Internet connection for a
private Ethernet network. The Router combines high-speed ADSL Internet connection, IP routing for the
Local Area Network (LAN) connectivity in one package.
The Router is easy to install and use. The DSL-522T connects to an Ethernet LAN or computers via standard
Ethernet ports. The ADSL connection is made using ordinary telephone line with standard connectors.
Multiple workstations can be networked and connected to the Internet using a single Wide Area Network
(WAN) interface and single global IP address. The advanced security enhancements, packet filtering and
port redirection, can help protect your network from potentially devastating intrusions by malicious agents
from outside your network.
ADSL
Asymmetric Digital Subscriber Line (ADSL) is a broadband network technology that utilizes standard twisted-
pair copper wire telephone lines to enable broadband high-speed digital data transmission and bandwidth
hungry applications for business and residential customers.
ADSL routers and modems provide faster downloads and more reliable connectivity to the user without loss
of quality or disruption of voice/fax telephone capabilities.
ADSL service operates at speeds of up to 24 Mbps downstream and up to 1 Mbps upstream. A secure
dedicated point-to-point connection is established between the user and the central office of the service
provider.
