Cisco HWIC-16A 16 Port High Speed WAN Interface HWIC16A

Description:

The Cisco HWIC-16A 16-Port High-Speed WAN Interface Card is a router expansion module designed to provide multiple asynchronous serial connections for Cisco Integrated Services Routers used in enterprise and industrial network infrastructures. It delivers sixteen asynchronous serial ports that enable connectivity to modems, terminals, console devices, and other serial communication equipment for remote management and data communication. Commonly installed in Cisco ISR platforms deployed in enterprise branch offices, telecom networks, and network management systems, this module enables high-density serial connectivity within router-based infrastructures. Network administrators, IT engineers, and system integrators use this module for serial device integration, remote terminal access, network infrastructure expansion, and replacement of legacy serial interface modules.

Applications:

The Cisco HWIC-16A interface card is used in enterprise and telecommunications environments where routers must support multiple serial connections for terminal server applications and device management. It enables connectivity between routers and serial-based equipment such as console servers, modems, industrial controllers, and legacy network devices. Typical deployments include enterprise branch offices, telecom infrastructure networks, remote management systems, and industrial communication environments where multiple asynchronous serial connections are required for monitoring and device control.
