That should shed some insight as to what pair the installer used to feed the house.

I can also add - sometimes the cable that runs to all your jacks get wired in series. Somebody opens a jack up and forgets to tie down "line 2 wires" and the circuit is broken. If you happen to know the first jack from the cabling outside - I would start with that one and move throughout the house.

Do the data lines (green/white white/green) need to be connected to line 2 through out the house or can they just remain intact and not hooked up to line 2 to complete the circuit? Does that make sense?
