The Cisco HWIC-16A is a 16-port asynchronous High-Speed WAN Interface Card (HWIC) used in Cisco Integrated Services Routers (ISR). It provides multiple RS-232 serial ports for asynchronous communication, commonly used for console server access, dial-in/dial-out services, and legacy device management.
This module is part of Cisco’s legacy WAN interface portfolio designed for branch office routers such as the Cisco 1800, 2800, 2900, and 3800 series.
Key Features
- 16 × asynchronous RS-232 serial ports
