One consideration is being able to plug an RJ-11 plug into an RJ-45 jack. (Not really a good idea, as it can bend the outside pins of the jack...) The center 4 pins on a RJ-45 jack are the same as a RJ-11 jack. Mikkel -- Do not meddle in the affairs of dragons, for thou art crunchy and taste good with Ketchup!
