The Cisco Single-Port Ethernet WAN Interface Card (WIC-1ENET) offers customers using a Cisco 1700 series router the option of an additional Ethernet port for enabling broadband Internet access or deployment of a perimeter LAN or demilitarized zone (DMZ). Ideally suited for small and medium businesses and small branch offices, the Ethernet WIC offers a cost-effective method for expanding the capability of the Cisco 1700 series router.

The Cisco WIC-1ENET extends the capabilities of Cisco 1700 series access routers, providing additional Ethernet ports for network deployments. When installed in any WIC slot of the router, this one-port 10BaseT Ethernet WIC enables delivery of secure Internet connectivity using any broadband access device, including digital subscriber line (DSL) and cable modems. The integrated 10/100 Fast Ethernet port on the Cisco 1700 series router remains connected to an internal LAN, with the second Ethernet port provided by the WIC-1ENET can be connected to an external DSL or cable modem. 

Alternatively, the WIC-1ENET can be used for deployment of a separate DMZ on the perimeter of the network. A DMZ enables Internet users to access public servers, including Web and File Transfer Protocol (FTP) servers, while maintaining security for the company's private LAN.  The Cisco 1700 series modular access routers with WIC-1ENET offers support for New World services, including virtual private networks (VPNs), voice over IP (VoIP), broadband, and combined voice and data networking. The addition of a WIC-1ENET offers a cost-effective alternative for implementing new broadband services, while preserving investment in existing equipment.
