Ethernet Over VDSL Ethernet over VDSL Solution Concepts Opportunities DSL Market • Broadband market is expected to reach 30% of households by 2003 • DSL is becoming the dominant broadband technology • Ethernet and DSL represent the most attractive broadband opportunity What is EoV technology ? Ethernet over VDSL enables the extension of Ethernet over telephone lines to a distances of 1200m using VDSL transport. 10Mbps (Full Duplex) + Telephone on one line How does EoV work? • Ethernet over VDSL transmits 10Mbps data over frequencies unused by the telephone service.
