Wow. I'm not sure I understood all of that. While I knew the answer to the OP question, what I am able to understand and learned from the article is that my thinking as to "why?" was way wrong. While I can't articulate the answer to "why?", now, thanks for setting me straight, C:Amie.
elgarteo95, I would recommend searching the forums for "cisco 350" and reading some of the posts. I have one and it works fine with my J720, but there are drawbacks you may want to know.
