IMPLEMENTING A POINT-TO-POINT

LAN EXTENSION

Two ADC G.shdsl modems can be implemented in a point-to-point application (also called back-to-back). In this application, the modems can be used to connect remote LANs to create L AN extensions. In this point-to-point application, one ADC G.shdsl modem is set to Remote mode and the other ADC G.shdsl modem is set for Central-Office mode. By bridging traffic between these two modems, you essentially create one extended LAN that allows the use of a single IP subnet.

Although you can set up multiple sessions on these modems, only one RFC 1483-Bridge sessions is required for implementing a point-to-point LAN extension.

The ADC modems comply with the standard G.shdsl data rate range of 192 kbps to 2304 kbps. Additionally, rates down to 64 kbps are supported only when using the G.shdsl modem in single-pair, point-to-point mode for a LAN extension application.

BEFORE YOU BEGIN. . .

Determine which of these implementations apply for your application: ❑ Quick Install—If your application does not require custom configuration, you can use the

default modem settings. To implement, the Remote mode modem is already configured with factory default configuration for implementing point-to-point LAN extension; no changes are necessary for this modem to impl ement service. The Central-Office modem requires only two configuration changes to set the modem to Central-Office mode. These changes are described in “Complete a Quick Installation” on page 64.

❑ Custom Configuration—If you implement custom configuration where you do not use

factory default parameters for your modems, refer to “Complete a Custom Configuration”

on page 66 to configure the Remote modem and to configure the Central-Office modem.

MM701G and MM702G User Manual 63

Complete a Quick Installation

COMPLETE A QUICK INSTALLATION

The modem is shipped with factory defaults as a Remote modem and does not require any additional configuration when used as a remote. Only the Central-Office modem requires configuration changes.

In a quick installation, you change configuration only for the Central-Office mode modem. The Remote modem uses its factory default parameters. To set up the Central-Office modem, follow the instructions in the following sections. The modems use a default bridging WAN session (

RFC1483-bridged) which has a predefined ATM connection using Virtual Path ID of 0 and

Virtual Channel ID of 35.
