Serial and asynchronous High-Speed WAN Interface Cards (HWICs) provide highly flexible connections for Cisco Integrated Services Routers. These HWICs help customers enable applications such as WAN access, legacy protocol transport, console server, and dial access server. You can mix and match HWICs to tailor cost-effective solutions for common networking problems such as remote network management, external dial-modem access, low-density WAN aggregation, legacy protocol transport, and high-port-density support.

  • 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.
