Cisco High-Speed WAN Interface Cards: Four Serial and Asynchronous HWICs

HWIC (High-speed Wan Interface Cards) is an upgraded and enhanced version of WIC. It provides higher speed and port density than current WICs. HWIC can help customers support WAN aggregation, Traditional protocol transfer, console server and dial-up access server applications. Customers can use various HWIC Portfolio Customized cost-effective solutions for common network problems, such as remote network management, external Low density WAN convergence, traditional protocol transport and high port density support.

Serial and asynchronous high-speed WAN interface cards (HWICs) provide highly flexible connections for Cisco 1800, 1900, 2800, 2900, 3800, and 3900 Series Integrated Services Routers. These HWICs help customers 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.

Cisco provides four serial and asynchronous HWICs:

• Cisco 1-Port T1/Fractional T1 DSU/CSU WAN Interface Card (HWIC-1DSU-T1)

• Cisco 1-Port Serial WAN Interface Card (HWIC-1T)

• Cisco 2-Port Serial WAN Interface Card (HWIC-2T)

• Cisco 2-Port Asynchronous/Synchronous Serial WAN Interface Card (HWIC-2A/S)

Their biggest difference is the number and functions of their ports. This is the comparison chart.
