This came with a new router and was not needed for the network design. The router was powered on with the hwic to make sure it was not defective but is sold as is. Here is some information about this card:

The new ADSL HWIC provides 1-port ADSL connectivity to a WAN. The single-port ADSL HWIC, combined with the Cisco 1841 integrated services router (ISR) and the Cisco 2800 and 3800 series integrated services routers (ISRs), provides high-speed digital data transmission between customer premises equipment (CPE) and a central office. This enables service providers and resellers to offer additional services by supporting features for business-class security, voice integration, differentiated classes of service (CoS), and managed network access with Cisco IOS Software. These value-added features, along with the manageability and reliability of Cisco IOS Software technology, provide the mission-critical networking that businesses require.
