1INTRODUCTION
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
