Overview
The Layer 3 Cisco 1-Port Fast Ethernet High-Speed WAN Interface Cards (HWICs) 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.
  • WAN access and aggregation
  • Legacy protocol transport
  • Dial access server
Legacy protocol transport Serial and synchronous/asynchronous ports are ideally suited to transport legacy traffic across a TCP/IP network, facilitating network convergence and eliminating costly separate leased lines for this traffic. Dial access server Asynchronous HWICs can connect to external dial modems to provide low-density dial access servers.
