♦The SmartSwitch™ Router 250
The SmartSwitch™ Router 250 provides Internet and Corporate
access for telecommuters, home and remote office workers, and
Internet users at high-speed asymmetrical data rates of up to 640 Kbps
upstream and 8.0 Mbps downstream.
The router takes full advantage of Asymmetric Digital Subscriber
Line (ADSL) technology and uses Asynchronous Transfer Mode
(ATM) to provide remote Ethernet LAN connectivity via a single
ADSL line. Because ATM technology supports multiple virtual circuit
connections, users connected to an Ethernet LAN can access several
network services simultaneously.
♦Cabletron Quick Start
The router features an easy-to-use Windows-based management
application. It also has several built-in features that let users connect
to a Network Service Provider (NSP) in minutes.
