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 CX82310 Single-Chip ADSL router 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 and an IEEE 802.3-compliant Ethernet
MAC interface to provide connectivity options, the CX82310 does not rely on
host PC drivers, and thus is not limited by them. The result is extreme ease-
of-use with active auto selection of the interface and simultaneous operation
of both USB and Ethernet. The CX82310 also features a PCMCIA-type
interface to an optional 802.11b wireless subsystem enabling ADSLWireless
Access Point solutions. All setup and provisioning is accomplished via a
simple intuitive Web interface which further enhances the user experience.
The CX82310 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.
A single-chip router, the CX82310 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
Internet access, video delivery, or other streaming media.
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 CX82310 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.
A high-performance, 16-bit parallel expansion bus is available for additional
functionality. This expansion bus provides an interface to a PCMCIA 802.11b
wireless system. Additionally, the expansion bus can be used to inferface to
a V.92/V.90 backup system.
