cyril7: You said, "...I recommend a local sparkie or data cabler to do the task, purhaps even a general handy man who is up to it."
From what Wheelbarrow said, it seems that I shouldn't need to get involved to this degree, as Chorus could, and would, do that. And no, under-house access isn't really feasible, otherwise I could have run a draw wire myself. The crawl space, if one could get through the concrete base, would possibly be accessible only to a ferret, if it wasn't full grown.
But I really need to be discussing this with whomever is doing the on-property fibre run and ONT installation. So, what is the name of this mysterious organization? Is this information not publicly accessible?
