 DSL cabling
I recently purchased a DSL router that has a CAT5 (RJ45) DSL input instead on the RJ11 phone jack. I believe that the white/blue and the blue/white wires are used on the CAT 5 connector, but I don't know which of the phone wires (black, red, green, yellow) use to hook up to the CAT 5.

Dear Gene,

In four conductor phone cable red and green are forming pair number 1, which will come on blue-white/blue pair in CAT5 cable.


Are you sure your DSL modem has TWO RJ45 jacks? One jack should be for a phone line input (and that is RJ11 on all devices I saw so far) and another one is Ethernet output (RJ45)

What is the model of your device? It will be interesting to check with the manufacturer.
