Question : How can I tell which DSL cable cord to get for my wall outlet?
I have tried the Cat5e R7J604 cord on the wall and on a DSL/Phone line splitter. Both cords I have are too big for the jack.

The Cat5 cable is not the right cable to plug into your phone line for DSL use. You need a plain old RJ11 telephone cable for that. The Cat5 cable is used to connect the DSL modem to your computer.
