HWIC-16A Cisco 16-Port Asynchronous High Speed WAN Interface Card

The HWIC-16A is a Cisco 16-port asynchronous high-speed WAN interface card designed to expand the serial connectivity options on compatible Cisco routers. It provides multiple asynchronous serial ports that are often found in networks requiring legacy serial communication support or asynchronous data transmission.

Built for environments where multiple serial devices need to be connected simultaneously, this module is commonly used in service provider networks, branch office installations, or any setup that relies on asynchronous serial links. Network administrators benefit from its flexibility and ability to integrate older serial equipment into modern Cisco routing platforms.

Key Features

• Offers 16 high-speed asynchronous serial ports for diverse WAN setups
• Operates at speeds up to 115.2 kbps per port to handle varied data loads
• Fits into Cisco HWIC slots for easy router expansion
• Supports asynchronous communication protocols for legacy device compatibility
• Maintains efficient serial data flow with minimal latency

This interface card is typically deployed in networks that require numerous asynchronous serial connections, such as telecom environments or specialized industrial networks. It plays a key role in bridging modern router platforms with existing serial-based infrastructure, ensuring continued operation without needing full network overhauls.
