The new Cable HWIC (HWIC-CABLE-E/J-2) is designed to comply with 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. This cable HWIC combined with the Cisco 2800 and 3800 Series Integrated Services Routers; Cisco 1841 Integrated Services Router; and Cisco IAD2430 Series 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.
