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
POTS, BA-ISDN PSD [dbm/hertz] ADSL SHDSL -40 EoV -60 10 -80 F [Mhz] <0.12 Mhz 0.9 Mhz 3.75 Mhz 8.0 Mhz 10 How does EoV work? • Ethernet over VDSL transmits 10Mbps data over frequencies unused by the telephone service. Voice Data
CPE • Small plastic unit • 1 port local loop • 1 port 10/100Base-T • 1 port Tel EoV Building Blocks Splitter EoV Module • EoV splitterPunch-down block • 30 ports PSTN • 30 ports local loop • 30 port RJ-11 VDSL • 8 EoV ports • 10/100Mbps Ethernet • Fits all OptiSwitch Chassis range • Rate limit per port

What is Cross Talk? • Transmission from one pair interfere with transmission from other lines • The more DSL lines on the same bundle, the more the chance For interference
About FEXT and NEXT Near End Cross Talk High Density of lines Far End Cross Talk Few lines, Long Distance
How does EoV compare with xDSL? • Network Topology • Network Protocol (ATM) • Power Spectrum Density/Distance • Line Rate

More about ADSL vs. EoV • Uses ATM as the Layer 2 • High cost of operation • Limited and expensive scalability • Complex installation, management and configuration • Limited for business deployment • Not scalable for speed • Not symmetric (By definition…) • ADSL for long distance, EoV for up to 1200m EoV ADSL
EoV Application - Carrier • Broadband Communication Services • Pricing suitable for Residential deployment • Ideal for Business applications • LAN to LAN applications • Fast enough for Web and FTP servers • Scalable for 10Mbps
EoV Application– Carrier II • Bandwidth Distribution for Wireless Broadband Carriers • Complimentary solution for Optical mesh • Two-way Satellite service providers • LMDS, WLL and BWLL • Backup for other Medium (Data over Power)
Le Hotel PSTN Internet EoV Application - MDU/MTU Hotel Room Data Voice CPE OptiSwitch Splitter PBX
MDU and MTU Application • Simultaneous Voice and Data support - speak while you surf • Utilizes existing telephone infrastructure – no rewiring needed • Fast Internet access • New office services can be offered to customers: • Printing, fax gateway, and voice over IP gateway
LAN Extension in Campus Environment • Large Campus areas can use existing cupper lines for Ethernet connectivity • Cheaper than digging up fiber • Ideal for: • Universities • Community Neighborhoods • Hospitals
