I am switching from Comcast HSI and Digital Voice to Verizon POTS and DSL. I have no NID. This house must have extremly old phone wiring. Phone wire comes into basement and just goes to a little block that looks like a grounding block then to a splitter and the two active phone lines go from there to two different rooms in the house using only Green and Red wires.I am going to have a problem getting the DSL ugh?
