Getting Started
1. Overview
X8821r and X8821r+ are ADSL/ADSL2+ series of customer premise
equipments that provide high-speed asymmetrical data transmission
on a single twisted copper pair. The DSL line interface supports
various ADSL standards, up to ADSL2+ with X8821r+. At the DTE
side these CPEs provide one 10/100 Ethernet interface for easy
connection to user’s PC or LAN environment. With built-in IP routing,
NAPT and firewall, these units serve as the gateway to the Internet
world. X8821r and X8821r+ deliver broadband access for
enterprises, telecommuters, home, and remote office workers with
high-speed data transfer requirements.
