Cisco 8-Port Async High-Speed WAN Interface Card

The Cisco HWIC-8A stands as a robust, compact solution designed to expand your router’s WAN capabilities with eight asynchronous interfaces. Each port supports data transmission up to 230.4 kbps, delivering reliable, concurrent WAN sessions across multiple sites without sacrificing performance. This high-density module is engineered for enterprise environments that demand dependable connectivity, straightforward integration with existing Cisco infrastructure, and streamlined cabling that keeps racks organized and airflow unobstructed. Whether you’re extending branch offices, connecting regional sites, or consolidating legacy WAN links, the HWIC-8A provides a scalable foundation for resilient, cost-effective wide-area networking. With Cisco’s proven reliability and industry-standard IOS compatibility, you gain a flexible, future-ready platform that helps your business stay connected, productive, and responsive to changing network demands.

• Eight asynchronous ports on a single HWIC module enable parallel data streams from multiple sites, allowing a flexible WAN topology that supports site-to-site communications, remote access, and failover without requiring additional interface hardware.
• Per-port performance reaches up to 230.4 kbps, delivering predictable, dependable throughput for legacy serial links, leased lines, and low-latency WAN applications while optimizing overall network costs and management complexity.
• High-density eight-port cabling simplifies installation and cable management, reducing rack footprint, improving airflow, and minimizing the risk of mis-wiring or tangling in busy data-center environments.
• Designed for enhanced dependability, the HWIC-8A integrates seamlessly with Cisco routers and IOS features to support robust uptime, reliable routing behavior, and compatibility with QoS, security, and monitoring tools across the WAN.
• Broad geographic coverage capabilities enable scalable deployment across distributed organizations, empowering IT teams to extend reliable WAN access to more sites with fewer hardware footprints and simplified maintenance.
