    Overview

    Cisco WIC-1DSU-56K4 Overview

    The Cisco WIC-1DSU-56K4 is a modular WAN interface card designed for enterprise-grade branch routers that require reliable low-speed leased-line connectivity. This plug-in module integrates a CSU/DSU with a single 4-wire port supporting 56/64 Kbps data rates over RJ-45, making it ideal for legacy circuits still common across Asia, Europe, Africa, and North America. With support for HDLC, PPP, and Frame Relay plus visual LED diagnostics, the WIC-1DSU-56K4 simplifies service turn-up, reduces CPE footprint, and offers a cost-effective path for distributors, SMB integrators, and end users modernizing mixed WAN environments.
