More Specifications

The HWIC-16A is a High-Speed WAN Interface Card (HWIC) from Cisco that allows for the expansion of asynchronous connectivity on Cisco routers. It provides 16 asynchronous serial ports, each with its own DCE/DTE connection and supports data rates up to 57.6 Kbps. It can be used to connect to a variety of serial-based WAN technologies such as T1/E1, ISDN BRI, and RS-232. It is a physical card that can be inserted into a Cisco router's expansion slot to provide additional connectivity options.


The model Cisco 16-Port Asynchronous High Speed WAN Interface Card is designed to provide high-performance connectivity for wide area networks. It offers 16 asynchronous serial ports that support data rates up to 2Mbps per port, allowing for a maximum aggregate throughput of 32Mbps. The card also supports a wide range of WAN protocols, including PPP, HDLC, and Frame Relay, providing flexibility in terms of configuration and compatibility with various types of serial-based WAN connections, such as T1, E1, and ISDN.

The card also provides advanced features such as Quality of Service (QoS) and security to ensure reliable and secure communication. The QoS feature allows you to prioritize and shape traffic to ensure that critical data is transmitted with the highest priority, while security features such as encryption and access control help to prevent unauthorized access to the network.

In addition, the HWIC-16A is designed to be easy to install and manage. It can be installed in a Cisco router and can be configured and managed using Cisco's IOS software, which provides a user-friendly interface and a wide range of management tools.

Reliability of WAN Interface Card

The HWIC-16A Cisco 16-port asynchronous high-speed WAN interface card has several reliability features that help to ensure its continued operation in the event of a failure.

  • Redundant power supply: The card is designed with a redundant power supply, which means that it can continue to operate even if one of the power supplies fails. This helps to ensure that the network remains up and running in the event of a power failure.
  • Redundant cooling: The card also has redundant cooling, which helps to ensure that it continues to operate even if one of the cooling systems fails. This helps to prevent overheating and reduce the risk of equipment failure.
  • Error detection and correction: The card is designed to detect and correct errors that may occur during data transmission, which helps to ensure the integrity of the data being transmitted.
  • Diagnostics: The card provides a range of diagnostic and troubleshooting features, including LED indicators, which can help identify and resolve issues quickly.
