Does Bell and Cogeco both work on the nodes? There is an brown box up the street from me which Bell usually works on all the time and now there is a Cogeco service van near the box. Here is a picture of that box. What is that box for?
That's a Bell JWI (Jumper Wire Interface/Interconnect) panel.
I doubt that Bell would be sharing that with Cogeco.
Cogeco tends to hang much of their stuff from the poles, but their nodes might be in a building here and there.
