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
