The new Cable HWICs are designed to comply with DOCSIS 2.0, Euro-DOCSIS 2.0, and J-DOCSIS 2.0 specifications and provide single-port cable modem connectivity for the Cisco modular integrated services routers and the Cisco IAD2430 series routers to the cable operator WAN. The cable HWICs provide high-speed digital data transmission between customer premises equipment (CPE) and a central office. This enables cable service providers and resellers to offer additional services by supporting features for business-class security, voice integration, differentiated classes of service (CoS), and managed network access with Cisco IOS Software. These value-added features, along with the manageability and reliability of Cisco IOS Software technology, provide the mission-critical networking that businesses require.
