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 unique in the industry. The ADSL Endpoint provides all of the benefits of a
transitional ADSL bridge/router, but at a significantly lower cost structure due
to its advanced architecture and Bill of Material reductions.
modem for single user deployments it has all of the robust and user-friendly
characteristics of a traditional ADSL bridge/router, including Web-based
configuration and provisioning. Additionally, the ADSL Endpoint does not
require a complex, host CPU burdening driver that is required by typical low
cost single user modems such as traditional ADSL-USB or ADSL-PCI modems.
Instead, the ADSL Endpoint processes all ADSL data completely, including
all ATM Segmentation and Reassembly (SAR), PPPoE, and PPP , etc. just as
a traditional ADSL bridge/router. The advantage of this type of architecture is
that the ADSL Endpoint provides the robustness of an ADSL bridge/router by
providing Ethernet frames to the PC and not relying on a host PC driver that
burdens the PC CPU.

capture additional revenue from advanced hardware and services all the while
continuing to provide extremely cost effective modems for mass-deployment.
step in a modular broadband gateway. Because the ADSL Endpoint provides
the processing power and capability of an ADSL bridge/router, the ADSL
Endpoint can be expanded with simple modular upgrades to support advanced
deployments, such as multi user ADSL routers, ADSL Wireless routers,
and/or ADSL VoIP terminals. The combination of low cost structure of ADSL
Endpoint with the ability of modular expansion makes the ADSL Endpoint an
ideal solution for service providers to mass-deploy and then upgrade on an as
needed per user basis.
