DSL MarketDSL 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 ?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?How does EoV work?
• Ethernet over VDSL transmits 10Mbps data over frequencies unused by the telephone service.

What is Cross Talk?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

More about ADSL vs. EoVMore 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
