1. Ethernet Over VDSL Ethernet over VDSL Solution Concepts Concepts Opportunities

2. 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

3. 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

4. How does EoV work? Ethernet over VDSL transmits 10Mbps data over frequencies unused by the telephone service. PSD [dbm/hertz] 3.75 Mhz8.0 Mhz F [Mhz] EoV -60 -40 -80 0.9 Mhz<0.12 Mhz ADSL SHDSL POTS, BA-ISDN 10 Data Voice

5. EoV Building Blocks CPE Small plastic unit 1 port local loop 1 port 10/100Base-T 1 port Tel Splitter EoV splitter Punch-down block 30 ports PSTN 30 ports local loop 30 port RJ-11 VDSL EoV Module 8 EoV ports 10/100Mbps Ethernet Fits all OptiSwitch Chassis range Rate limit per port

6. EoV in the last mile Home PSTN C.O. Telephone Data Ethernet over VDSL + Telephone

7. EoV solution 10 Mbps 100 Mbps 1000 Mbps OptiSwitch OSM Local Loop Home Server Farm NMS PSTN

8. 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

9. About FEXT and NEXT Near End Cross Talk High Density of lines Far End Cross Talk Few lines, Long Distance

10. How does EoV compare with xDSL? Network Topology Network Protocol (ATM) Power Spectrum Density/Distance Line Rate

11. Legacy DSL Network Topology DS3/OC3 OC3/OC12 OC12/OC48 Access Terminator Router Local Loop DSLAM Home Server Farm NMS

12. ADSL model disadvantages ADSL uses higher power of transmission (PSD) it causes: –Longer Distance = Higher power = more problems Spectrum allocation close to RF – Every open wire is a radio antenna PSD [dBm/hertz] 40 dBm 60 dBm EoV ADSL

13. 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

14. 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

15. 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)

16. EoV Application - MDU/MTU EoV Application - MDU/MTU Le Hotel PSTN Internet PBX Hotel Room Voice Data CPE Splitter OptiSwitch

17. 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

18. 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
