Ed, the reference to the rj45 is to the plugs on the cable the wiring digram you show is for a rj 45s. we dont use the suffix's here a rj45 is a network cable the rj 11 is a telephone cable we keep it simple here, the cable tipe is called after the plug that is on it not the wiring. see link. RJ 45

The pri uses a standard network cable, sorry about the mix up if you came over here and ask for a rj48 cable you would just get a blank look :shrug:
