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. (See Figure 2.) 
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. (See Figure
3.)
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.
