Cisco integrated services routers offer a wide variety of WAN connectivity modules to accommodate the range of application needs in customer networks. The Cisco 1-Port BRI U High-Speed WAN Interface Card (HWIC) provides BRI-U-based WAN connectivity for modular routers deployed in small to medium-sized businesses (SMBs) and enterprise branch offices.

Flexibility and investment protection are key features of the Cisco 1-Port ISDN U interface HWIC, which supports Cisco's commitment to providing customers with maximum flexibility through modular HWICs that are compatible with award-winning router platforms. When WAN bandwidth requirements or service provider pricing changes, users can easily adjust WAN services by changing the software configuration or replacing the HWIC. Since the same card can be used on Cisco 1841, 2800, and 3800 Series router platforms, the number of stocking units can be reduced, and the HWIC can be redeployed from one platform to another.

Enhanced reliability is another advantage of this integrated solution, as it has fewer components and, consequently, fewer points of failure, leading to improved overall reliability.
