The longer I work at my job the more I realize what I don't know. One of the major areas that I really need to learn more about is telecommunications. I understand what happens once it hits the equipment I support (for the most part). I just don't have a good grasp of what happens before it gets there. I understand the basics but I really want to learn more. On the recommendations of a couple of of co-workers I picked this up. I think it's going to help.
