I want to disconnect at least two of them, and I am thinking the ones in the photos with the pair of Orange and Black and Red and White are safe to disconnect?
Is the outlet with the thicker Blue and White wires connected to the larger yellow object the master and is the larger yellow object a filter?
I want to disconnect these as there is no longer a landline in the house, but need at least one to remain for the VDSL modem
