Cisco 1-Port Fast Ethernet High-Speed WIC interface cards/adapter

1-Port Fast Ethernet High-Speed WIC The Layer 3 Cisco® 1- and 2-Port Fast Ethernet High-Speed WAN interface cards (HWICs) (see Figures 1 and 2) supported on the Cisco 1841, Cisco 2800, and Cisco 3800 Series Integrated Services Routers offer small-to-large-sized businesses and enterprise branch-office customers the option to add Layer 3 routed ports with many advanced features, including quality-of-service (QoS) and rate-limiting capabilities.

Feature Highlights
The Fast Ethernet routed ports on the HWICs have the same characteristics and features as the onboard LAN interfaces for the integrated-services-router platforms. Along with Layer 3 connectivity, such as per-port access control lists (ACLs), routing, and IP addressing, these HWICs provide functions equivalent to those of onboard Fast Ethernet routed ports.
