ABOUT THE PRODUCT
You have purchased the PairGain Megabit Modem 500L
that connects your Ethernet LAN to service providers for
instant and high-speed access to the Internet or to other
types of Wide Area Network (WAN) applications. The
modem provides this service over a single-pair telephone
line with downstream ADSL transmission up
to 1.5 Mbps. The upstream ADSL transmission is up to
512 kbps. You can also receive telephone service over the
same single-pair line as your data.
The Megabit Modem 500L uses ATM over DMT ADSL technology to provide this high-speed
transmission between the modem and the service provider. Asynchronous Transfer Mode
(ATM) provides transmission of fixed-size cells over preestablished connections. The
Asymmetric Digital Subscriber Line (ADSL) provides rate-adaptive transmission which means
the service provider can deliver the best possible transmission rate to you based on distance and
line conditions.
The Megabit Modem 500L is easy to install and configure. To install the modem, you:
• connect a telephone cable from the modem to a wall phone jack for ADSL service
• connect a cable from the modem to a PC or an Ethernet hub for LAN service
• connect a power cable to a local power source
To configure the modem, launch a Web browser on your PC and load the Megabit Modem
Configuration and Management Tool Web pages that guide you through configuration. Use the
Web page called EasySession™ to configure up to 3 Internet or other WAN sessions with
service providers (you can activate only one session at a time). You can also configure other
system parameters and monitor ADSL, LAN, and other networking functions using the Web
pages.
DSLview™ LEDs on the modem front panel provide continual status at-a-glance for network
and modem connections.
