Cisco 16-Port Asynchronous High-Speed WAN Interface Card (HWIC-16A)
Brand: Cisco · SKU: HWIC-16A · MPN: HWIC-16A · Category: Components
The Cisco HWIC-16A is a 16-port asynchronous serial High-Speed WAN Interface Card designed for Cisco Integrated Services Routers (ISRs). It enables RS-232 asynchronous communication for applications such as WAN aggregation, transport for traditional protocols, console servers, and dial access servers. It utilizes two high-density 8-port connectors which connect via CAB-OCTAL-ASYNC cables to provide 16 individual RJ-45 console-style serial ports. The module supports a maximum asynchronous serial data transfer rate of up to 230.40 Kbps per port. Supported protocols include PPP, HDLC, Frame Relay, PAP, CHAP, X.25, TCP/IP, SDLC, and Binary Synchronous Communications (Bisync).
