CHAPTER 1

INTRODUCTION

Congratulations on your purchase of the Barricade 2-Port Broadband Router with built-in ADSL Modem. We are proud to provide you with a powerful yet simple communication device for connecting your PC to the Internet.

The Barricade is an Asynchronous Digital Subscriber Line (ADSL) network device that provides high-speed Internet access over existing phone lines. It supports both full-rate Discrete Multi-Tone (G.dmt) connection (up to 8 Mbps downstream and 640 Kbps upstream), as well as the more economical splitterless G.lite connection (up to 1.5 Mbps downstream and 512 Kbps upstream).

The Barricade delivers concurrent data and voice over a single connection (using a splitter for G.dmt but not G.lite). It also supports a Rate Adaptive algorithm to maintain data integrity under almost all existing conditions, including various connection lengths and degraded signal quality. Because all data crossing the ADSL link is encapsulated in ATM frames, the Barricade can be connected directly to any standards-compliant DSL Access Multiplexer (DSLAM) at your service provider’s central office. Data can then be sent through an ATM backbone, and out to the Internet. Moreover, there’s no need to install any new lines, nor is there is any need for a truck roll to the customer’s premises when using splitterless G.lite ADSL.

The Barricade provides an always-on digital connection that eliminates dial-up delays, and supports transparent reconnection when initiating a network request. Full support for Asynchronous Transfer Mode (ATM) protocol also provides access to a wide range of advanced transport features, including support for real-time video, and other multimedia
