Cisco WIC-2T 2-Port Serial WAN Interface Card for Modular Cisco Routers

Cisco WIC-2T is a two-port serial WAN interface card that enables high-speed point-to-point or Frame Relay serial connections for Cisco modular routers.

Each port uses a Smart Serial connector, which allows a wide variety of serial interface types via optional Smart Serial cables (V.35, RS-232, X.21, etc.).

The WIC-2T supports synchronous serial communication with speeds up to 8 Mbps per port (depending on cable type and router support).

It is ideal for leased line connectivity, WAN backup links, and enterprise WAN solutions where reliability and flexibility are essential.
