Broadband Internet Connectivity
Conexant's broadband communications portfolio includes a comprehensive
suite of semiconductor solutions that enable the digital home and information
network. The Conexant AccessRunner CX82320 Single-Chip ADSL Endpoint is
optimized to address the growing demand for high-speed Internet access,
and it does so as a single, highly integrated and cost-effective solution.
Featuring a USB 1.1-compliant interface, the CX82320 does not rely on host
PC drivers, and thus is not limited by them. After a simple Plug-n-Play driver
installation, all setup and provisioning is accomplished via a simple intuitive
Web interface which further enhances the user experience.
The CX82320 is built upon a scalable architecture and is fully compliant
with full-rate ADSL (T1.413 Issue 2 and G.dmt standards) and the `splitterless'
G.lite (G.992.2) standards, including Annex A (ADSL over POTS) and Annex B
(ADSL over ISDN). This broad level of compliance ensures that products based
on the AccessRunner can address the existing installed base and continued
deployment of ADSL lines. Telephone companies, for example, can deploy
full-rate, splitterless full-rate, as well as G.lite to the consumer.
The single-chip CX82320 allows an "always on" high-speed broadband
connection to the Internet. It uses existing twisted-pair telephone lines to
deliver data rates at more than 100 times the speed of conventional dial-up
modems, and without the interruptions that can plague telephone service.
Data transfer rates of up to 8 Mbps downstream and 1 Mbps upstream make
it the ideal solution for high-bandwidth applications for corporate networks,
Internet and video delivery.

Networking support includes both bridge and router modes. The
router mode includes advanced features such as Network Address
Translation (NAT), Dynamic Host Protocol (DHCP) and Routing
Information Protocol (RIPv2). The router integrates the hardware
functions of the network processor, ADSL DMT engine, Analog
Front End (AFE) and Line Driver. Through the use of a flash file
system, firmware upgrades are easily managed. This allows for
simple, reliable product updates or feature enhancements.
