This is just something I'm curious about. I get line noise sometimes, especially after it rains. It's just annoying when you're trying to talk on the phone, but it makes a computer dial-up connection impossible. So anyway, when this happens, I call Sprint. They come out and fix the problem. But how, exactly, do they do that so quickly and easily? If moisture in the ground is messing up the underground wiring, what do they do out there at the yellow phone box near the road that can actually fix the noise problem? Just one of those things that make me go "hmmmmm."
