Cisco WIC-2A/S 2-Port Async/Sync WAN Interface Card

The dual-serial port WAN Interface Card (WIC-2A/S) provides higher levels of serial port density for a single WIC and is supported on the Cisco 1700, 2600, and 3600 series. The low serial speed WIC-2A/S supports up to 128 Kbps synchronous or 115.2 Kbps asynchronous serial links. Each port on a WIC is a different physical interface and can support different protocols such as Point-to-Point Protocol (PPP) or Frame Relay and Data Terminal Equipment/Data Communications Equipment (DTE/DCE). This WIC supports mixed asynchronous and synchronous operation on a single card as well.
