Very high-speed digital subscriber lines (VDSL)

Very high-speed digital subscriber lines (VDSL) are overviewed with an emphasis on the basic architecture, applications, and data rates, as well as the technological challenges of the design. Discussions of the telephone line environment, radio-band interference ingress and egress, impulse noise, and symmetric and asymmetric multiplexing are included along with the consequent description of a popular implementation.
