I was wondering if it would be possible to set up a computer that uses two phone lines and two modems when available, but would be able to connect with just one if it had to, without disconnecting hardware and making major software changes. This would be some kind of a switch. I have two phone lines but seeing as how I have to use at least one sometimes for calls this would be a nice option. Also I have heard of being able to run 2 modems to increase access speeds but would this require two isp accounts. I live about 2 blocks out from RoadRunner and they dont plan on expanding soon.
