The CX82310 is built upon a scalable architecture and is fully compliant wi th
full-rate ADSL (T1.413 Issue2 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 theA ccessRunnercan address the existing installed base and
continued deployment of ADSL lines. Telephone companies, for example, can
deploy full-rate, splitterlessfull- rateas well as G.lite to the consumer.
A single-chip router, the CX82310 allows an always-on high-speed broadband
connection to theIn ternet.It uses existing twisted-pair telephone linesto
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 upst reamm ake
it the ideal solution for hi gh-bandwidtha pplications for corporate networks,
Internet and video delivery.
Networking support includes both bridge and rout er modes. The router mode
includes advanced features suchas Net workAd dressTranslation (NAT),
Dynamic Host Protocol (DCHP) and Routing Information Protocol (RIPv2)
processor, ADSL DMT Engine, Analogue Front End (AFE) and Line Driver.
Through the use of a flash file system, firmware upgrades are easily manag ed.
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 agluel ess interface to PCMCIA
802.11b wireless system. Additionally, the expansion bus can be used to
interface to aV .92/V.90backup system.
