My new apartment has three bedrooms and each has a RJ45 keystone jack (I assume there are ethernet cables connected in the wall). There is a patch panel in the living room and I want all my rooms to be connected via ethernet. I see ethernet cables at the patch panel labeled according to the rooms. However only a pair of wires from each cable (blue pair) is connected to a panel which I'm not sure what it does. I was told it is for the telephone. Please see the attached pictures. https://www.flickr.com/photos/127264524@N02/ Please help me with the following questions 1) What is the bottom panel called and what is it for? 2) Why is each room connected in this way? I mean the developer has laid the cables already, why not just connect each cable to a keystone jack. I'm sure a keystone jack doesn't cost much, and I doubt anyone will need 4 different phone lines in a home. 3) I was told to just cut off that pair of connected wires (blue and blue-white) and connect the 4 twisted pairs to a new keystone jack just like normal for ethernet connectivity. Can I do that? Will that affect any electricial connection in my unit? Thanks for sharing
