Cisco HWIC-16A is a 16-port asynchronous serial High-Speed WAN Interface Card that enables RS-232 asynchronous communication for Cisco Integrated Services Routers (ISRs).
It's designed for terminal server applications, modem banks, SCADA systems, or other legacy serial deployments that require a large number of asynchronous ports.
Using a high-density 68-pin connector, the HWIC-16A connects to Octal Async cables (CAB-OCTAL-ASYNC) that fan out to 8 individual RJ-45 console-style serial ports.
