Abstract

A digital subscriber line (DSL)/home phoneline network router provides DSL connectivity and home networking support. The router provides a single phoneline connection (RJ-11 jack) to access either the Internet or a home phoneline network. In terms of hardware, the router may include a central processing unit, a DSL modem, and a home phoneline networking device (media access controller and home phoneline networking physical interface). In terms of software, the router may include a DSL driver, a local area network (LAN) driver, a media access controller driver, network routing stacks and a real time operating system.

Claims

1. A digital subscriber line/home phoneline network router, comprising:

a central processing unit;

a digital subscriber line modem coupled to the central processing unit;

a media access controller coupled to the central processing unit;

a home phoneline networking physical interface coupled to the media access controller;
