OVERVIEW<br />
VDSL2 (Very High Bit-Rate Digital Subscriber Line) is at the high-end of<br />
all the DSL technologies, offering the best combination of fiber optic and<br />
copper to provide high-speed broadband Internet access. VDSL’s primary<br />
application is in providing a broadband data service to multi-tenant<br />
residential or commercial buildings. In this implementation, fiber optic<br />
cable carries data from an Internet Service Provider to the building; then<br />
the installed telephone copper wires take the data and deliver it to<br />
individual units within that building.<br />

VDSL provides high-speed Internet access over existing phone lines by<br />
making use of previously unused frequency bandwidth above the voice<br />
band (i.e., up to 30 MHz with VDSL2). By placing VDSL signals above the<br />
frequency of the voice signal, a VDSL service can coexist on the same line<br />
as other telephone services. VDSL can operate symmetrically, providing the<br />
same data rate in both directions, or asymmetrically, providing a higher data<br />
rate in the downstream (receive) direction than in the upstream (transmit)<br />
direction.<br />
