Cisco 1-Port Serial High-Speed WAN Interface Card for Integrated Services Routers

The Serial and Asynchronous high-speed WAN interface card (HWIC) provides highly flexible connections for Cisco 1800, 2800 and 3800 Series Integrated Services Routers. This HWIC helps to enable applications such as WAN access, legacy protocol transport, console server and dial access server. You can mix and match HWICs to tailor cost-effective solutions for common networking problems such as remote network management, external dial-modem access, low-density WAN aggregation, legacy protocol transport and high-port-density support.
