CISCO WIC-1B-U-V2= INTERFACE CARD

The WIC-1B-U card offers a single ISDN BRI U-interface. The WIC inserts into a mixed-media network module or directly into the WIC slot on the Cisco 1600, 1700, or 2600 chassis. The ability to add BRI connectivity via a WIC allows administrators to maximize valuable slot space while providing additional connectivity options, such as Ethernet, on the same module.
