I wanted to have my phone & computer network line share a wall mount plate, therefore I purchased RJ45 & RJ11 keystone jacks for use. The JR11 keystone have 3 pairs (6 wires) slots and one pair (2 wires) un-use, while the phone jack have only 4 or 2 wires.
I know that phone normally only need one pair (2 wires) to work, but I?m not sure as to which pair I should punch down?
And what lines should I use for phone system that uses 3 lines?
Thanks
