Megabit Modem 500L Installation Manual 1

PRELIMINARY

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.

•rate-adaptable ADSL transmission downstream at up to 1.5 Mbps and upstream at

up to 512 kbps

•Internet or other types of WAN applications and phone service over your existing

phone line

•Point-to-Point Protocol (PPP) encapsulation method

•Password and Challenge-Handshake Authentication Protocols (PAP/CHAP) for

authentication of PPP sessions

•Network Address Translation (NAT) protocol to map the user to the PPP session

•Dynamic Host Configuration Protocol (DHCP) server to provide network configuration

information including IP addresses to LAN devices

•TFTP to download software

•AccessGain™software to provide access through an HTTP server to configure, manage,

and monitor the modem through a Web-based interface

•SNMP agent for management through any industry standard SNMP platform

•autodetecting 10/100BASE-T Ethernet port for connection to the LAN

•DSLview™LEDs to provide continual status at-a-glance of power, LAN, and

ADSL connections

•ATM technology with three virtual channels to allow one active Internet or other

WAN application session at a time

•PriorityVoice™to allow full deployment of the modem without splitters or microfilters

•InstaConnect™to sense phone activity and optimizes performance

On a Megabit Modem 500L, you can configure three PPP over ATM sessions. However, you

can enable only one of the sessions at a time. You assign the user to the session that is active.

Chapter 9 on page 55 provides more information about the technologies implemented in the

Megabit Modem 500L.
