Quoth the article: "a major business benefit in locations where it is not physically, economically or aesthetically viable to lay new fiber cables all the way into residences. Instead, fiber can be brought to the curbside, wall or basement of a building and the existing copper network used for the final few meters." I interpreted "the premise" as the building, but perhaps the conventional interpretation is the entire grounds. Either way, this is certainly about squeezing more out of the existing copper.
