What is the difference between RJ11 and RJ25?

RJ11, RJ14, and RJ25 all use the same six-position modular connector, thus are physically identical except for the different number of contacts (two, four and six respectively) allowing connections for one, two, or three telephone lines respectively. Cords connecting to an RJ11 interface require a 6P2C connector.
