1. Ethernet over VDSL Broadband access over existing copper cables

2. Ethernet over VDSL Ethernet over VDSL enables creation of an Ethernet link over telephone lines with distances of up to 2.4 Km using VDSL as the transport medium Data rates of up to 10Mbps, Full duplex, in parallel to the voice line (POTS/ISDN) 10Mbps Ethernet Voice

3. How does EoV work? Ethernet over VDSL transmits 10Mbps data over frequencies unused by the voice services 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

4. EoV Building Blocks CPE Small 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 RJ 11 EoV ports Fits into OptiSwitch Chassis Rate limit per port

5. EoV Product Line Module range: –8 port EoV Line Terminator (LT) side (Central office) –8 port EoV Network Terminator (NT) side (Customer Premises) –8 port Long range EoV (Central office - LT) –8 port Long range EoV (Customer Premises - NT) –4 ports NT + 4 ports LT –4 EoV ports + 2 100Base-Fx ports –4 EoV ports + 2 10/100Base-Tx ports –4 EoV ports + 1 FO + 1 UTP CPE –EoV –Long range EoV 30 port Splitter

6. EoV Applications 8 EoV links EoV High-speed Trunk EoV Repeater 2.4Km Optical Ring with EoV Add-Drop EoV Ring with UTP Add-Drop

7. EoV Features Built in diagnostics tools to enable highest rate possible and link quality measurement Link integrity application for automatic optimal configuration including support for changes in physical conditions (addition of users / weather)

8. VDSL ETSI Standards ETSI Standards define Band Allocation and Link Power Spectrum Density (PSD) –ETSI Plan 997 – Europe –ETSI Plan 998 – U.S.A and Japan PSD [dbm/hertz] 0.1383.755.18.512.0 -60 F [Mhz] 0.9 0.9-3.03.75-5.1 12 12

9. EoV Rate/Reach Symmetrical traffic is mandatory –EoV software configurable options: 10Mbps full duplex – 1200m ETSI 997 compliant 4Mbps – 1200m ETSI 998 compliant 4Mbps – 1200m –Long range EoV 4Mbps – 2400m Download Upload

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

11. EoV Carrier solution 10 Mbps100 Mbps1000 Mbps OptiSwitch OSM Local Loop Home Server Farm NMS IPPSTN

12. EoV in the last 100m Bandwidth Distribution for Wireless Broadband Carriers –Complimentary solution for Optical wireless –Two-way Satellite service providers –LMDS, WLL and BWLL Backup for other Medium (Data over Power)

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

14. 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

15. LAN Extension in Campus Environment Large Campus areas can use existing copper lines for Ethernet connectivity Less expensive than digging fiber Ideal for: –Universities –Community Neighborhoods –Hospitals –Industry

16. Conclusion EoV is ideal for Broadband access for Business and residential users Standards compliant Flexible distance and interface options Seamless integration all the way to the top (and into the OptiSwitch family) Broadband Services
