 RJ11 to RJ45
1)I have a VoIP adapter connected to my Router in the wiring closet. VoIP adapter has a RJ11 female. I have Cat5e running from my closet to wall faceplate with one end (near VoIP box) having RJ45 male and other end (wall faceplate) RJ45 female. I have connected my phone to wall faceplate RJ45 socket using standard RJ11 patach cable that came with phone. I need a patch cable that connects VoIP RJ11 to my CATe RJ45 at the wiring closet. What are the pin connections? Does any standard Rj11 to Rj45 patch cables/connector adaptors available?
2) When you plug a RJ11 male into a RJ45 female socket which 4 of the 8 RJ45 pins are connected?

Dear D,

It sounds like you have a DSL unit and you are trying to conect it to an ethernet system. These are two different types of signals and cannot be directly connected to each other.
