3 way switch question
I wonder why someone would have planned this layout or is this an error.
A ceiling fixture is operated by 2 switches. If switch #1 is up then flipping switch #2 up can turn the light on. But if switch #1 is down, then switch #2 cannot turn the light on, whether flipped up or down. If switch #2 is up, then flipping switch #1 up will turn on the light; but if switch #2 is down, then flipping switch #1 up cannot turn the light on. In other words, switch #1 seems to just operate as a shut off for the circuit that runs to switch #2. To me, this would appear to be an error. These switches are only three steps apart. Why have switch #1 if its only function is to render #2 ineffective?
Question 2: I would like to have this operate so that either switch can turn the fixture on or off. When I open up the boxes, what should I be looking for, to determine what I have here and what would be needed to make it so that either switch can turn the fixture on or off?
Thanks, Gary

Is there both a two conductor cable (white and black) and a 3-conductor cable (white black red) in both switch boxes or just one box with two cables and one box with just a 3-conduvtor cable?
