Cisco WIC-2A/S Dual-Port Asynchronous Serial WAN Interface Card

Cisco WIC-2A/S is a dual-port asynchronous serial WAN interface card designed for Cisco modular routers.

It provides two asynchronous serial interfaces, allowing for flexible serial communications over legacy WAN protocols such as SLIP and PPP.

Ideal for low-speed data connections, SCADA applications, console access, and out-of-band management, the WIC-2A/S is commonly used in government, utility, and enterprise environments.

Fully compatible with a range of Cisco routers, this WIC enables organizations to maintain reliable serial communication while transitioning to newer IP-based infrastructures.
