What's "cable"?
You guys must live in South Korea or another technologically advanced country. Tops available to me is 1.2M down, 750K up on a good day. I caught a fellow a couple of months ago marking the underground cable along side the road with his paint and flags. Since the county had just resurfaced the road, I didn't figure it was for more road work. It turns out that CenturyLink is thinking about running some real fiber up the road and the guy was from their contractor doing a bit of surveying.
That could make things quite pleasant if it extended to the DSL service.
