Introduction
Congratulations on your purchase of the ADSL Router. This router
provides high performance, complete telecommunications and
networking solutions for your home or branch office.
This chapter provides an overview of the asymmetric digital
subscriber line (ADSL) Discrete Multi-Tone (DMT) router. It also
describes the general applications available with the ADSL Router.
1.1 Overview
The ADSL Router provides home connectivity to an ADSL service
provider network over an ADSL/Asynchronous Transfer Mode (ATM)
physical layer. The router can run upstream maximum transmission
rates of 640Kbps and downstream maximum transmission rates of
8Mbps. The actual rate depends on the copper category of your
telephone wire, distance from the central office and the type of ADSL
service subscribed. A four ports switching hub of the ADSL Router is
provided for connection to an Ethernet LAN or Ethernet-equipped PC,
and this router is easy to install and to configure.
