Cisco WIC-1DSU-56K4-RF

The Cisco platforms offer a wide variety of serial connectivity modules to accommodate the range of application needs in customer networks. The serial network module family for the Cisco 3600 series assures customers that they can choose a serial connectivity solution that fits their requirements. Available as network modules or WAN interface cards, serial connectivity options offer several port densities, synchronous and asynchronous alternatives, and integrated channel service unit/data service unit (CSU/DSU). As modular components, they are easily and inexpensively field upgradeable as customer requirements change.The single-port, four-wire, WIC-1DSU-56K4 card combines a DSU/CSU into a single card with 64-kbps maximum throughput speed. A DSU is a device used in digital transmission for connecting data terminal equipment to a digital transmission service. A CSU is a digital interface device that connects end-user equipment to a local digital telephone loop. The four-wire DSU WAN interface card performs CSU/DSU functions for both dedicated (DDS) and four-wire switched 56-kbps data networks. Compatible with the Cisco 1600 series, this WAN interface card module provides an all-rate synchronous interface to any dedicated DDS point-to-point or multipoint network compatible with the AT&T; Publication 62310 standard. This WAN interface card provides a compact, self-contained unit without the clutter of external devices and cables.
