- 1-port Analog Modem WIC
The ADSL HWICs provide ADSL connectivity to a WAN. These HWICs, combined with the Cisco 1841 integrated services router (ISR) and the Cisco 2800 and 3800 series integrated services routers (ISRs), provide high-speed digital data transmission between customer premises equipment (CPE) and a central office. This enables 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.
