Serial and asynchronous high-speed WAN interface cards (HWICs) provide highly flexible connections for Cisco® 1800, 2800, and 3800 series integrated services routers. These HWICs help customers to enable applications such as WAN aggregation, legacy protocol transport, console server, and dial access server. Customers 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.
