Cisco HWIC-1VDSL= Network Switch Module Networking

The VDSL HWIC provides 1-port VDSL2 (Figure 1) connectivity to a WAN. Combined with the Cisco 1941 Integrated Services Router (ISR G2) or the Cisco 2900 or 3900 Series Integrated Services Routers (ISR G2), this HWIC provides high-speed digital data transmission between customer premises equipment (CPE) and a central office (DSL access multiplexer [DSLAM]). Thus service providers and resellers can offer additional services by supporting features for business-class security, voice , video, and data 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.
The 1-port VDSL2 HWIC is supported on the Cisco 1941, 2901, 2911, 2921, 2951, 3925, and 3945 ISR G2 starting with Cisco IOS Software 15.0.1M1.
