Title
(EN) Electrical isolation techniques for DSL modem
Abstract
(EN)

One embodiment of the present invention provides a DSL modem for coupling a transmission line to a communication system interface, the modem having digital isolation and power isolation. Another embodiment of the present invention provides a method for communicating power signals and data signals between a first-side of a modem and a second-side of the modem, the first and second sides of the modem being electrically isolated from one another.
