The Cisco Multimode VDSL2 and ADSL2/2+ GRWICs provide 1-port multimode VDSL2 and ADSL2/2+ WAN connectivity. In combination with the CGR 2010, this GRWIC provides high-speed digital data transmission between remote energy infrastructure and the central office (DSL access multiplexer [DSLAM]), usually located on the service provider premises. This capability helps enable the energy operations to take advantage of the business-class WAN connection features such as security, differentiated classes of service (QoS), and managed access with Cisco IOS ® Software over existing telephony infrastructure. These value-added features, along with the flexible manageability and reliability of Cisco IOS Software, provide mission-critical networking features that energy organizations need.
