Cisco HWIC-2A/S 2-Port WAN Interface Module Card "USED" HWIC2A/S

DESCRIPTION:
The Cisco HWIC-2A/S is a two-port asynchronous/synchronous serial WAN interface card designed for Cisco Integrated Services Routers (ISRs). This HWIC provides reliable serial connectivity for legacy WAN infrastructures, supporting both synchronous and asynchronous communication modes. It's ideal for mission-critical applications such as frame relay, point-to-point leased lines, and low-speed serial connections in government, financial, or industrial settings.
