I don't really know what I am talking about. I only said "secondary" as there has been some discussion elsewhere in this thread if what we have in the ground is a splitter or an aggregation node.
This should show a picture of what is on some of the poles. As I understand it from information on the web this could be a DP, or a splitter or a splitter/DP or a transition joint.
