Ethernet Over VDSL Ethernet over VDSL Solution Concepts

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 Eo. V technology ? Ethernet over VDSL enables the extension of Ethernet over telephone lines to a distances of 1200 m using VDSL transport. 10 Mbps (Full Duplex) + Telephone on one line

How does Eo. V work? • Ethernet over VDSL transmits 10 Mbps data over frequencies unused by the telephone service. POTS, BA-ISDN PSD [dbm/hertz] ADSL SHDSL -40 Eo. V -60 10 -80 <0. 12 Mhz 0. 9 Mhz Voice 10 3. 75 Mhz Data F [Mhz] 8. 0 Mhz

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

Eo. V in the last mile Telephone Data PSTN C. O. Home Ethernet over VDSL + Telephone

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 Eo. V compare with x. DSL? • • Network Topology Network Protocol (ATM) Power Spectrum Density/Distance Line Rate

More about ADSL vs. Eo. V • 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, Eo. V for up to 1200 m Eo. V ADSL

Eo. V 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 10 Mbps

Eo. V 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)

Eo. V Application - MDU/MTU Le Hotel Room Data Voice CPE Opti. Switch Splitter PBX Internet PSTN

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
