That's not true. DSL and ISDN operate over analog telephone circuits.
Remove the little filter(s) that come with your DSL modem and you'll
probably be able to hear the carrier. Cable modems use an RF carrier,
still analog. Theory of operation and carrier frequencies are
definitely different from your standard modem, but they're still
analog.
