Wondering if this is okay.
I have a cat5 cable running from downstairs to upstairs.
I was thinking of taking the VDSL signal from downstairs to upstairs in 1 pair of the Cat5 cable, and then in the same Cat5 cable use 2 pairs (only 2 pairs are needed for 100Mbits Ethernet) to return back downstairs 100Meg Ethernet (from the router upstairs that has been fed the VDSL signal).
This would avoid running another cable which would be in close proximity anyway.
How would the two signals affect each other being in the same binder?
