      Strange Noise Margin Behaviour

      I've noticed recently that if a plug in an ethernet cable to my router, plug in only its not actually connected to anything, the noise margin increases by as much as a couple of db. If I the plug the other end of the cable into a homeplug that's not actually switched on at the mains it'll increase even more by a small amount.

      Any one care to explain what's going on?
