Re: Why did comcast install these boxes? While I'm not sure the pictured box is actually a Comcast box, they are generally used for power supplies. The node, amp, splice containers, whatever else, will be up on the strand. Hell, even the power supplies can be in a small enough cabinet to be mounted up on the pole. Though of course I know some areas will be different, especially with underground plant.
These power supplies also usually contain batteries to provide DC backup power in the event of local power outage. There can also be a separate cabinet that houses a generator to provide run time longer than the batteries can provide. Some of the larger cabinets (usually only seen in more rural areas) will have the generator built in with the main cabinet.
(This part below isn't really to you Kommie , more to the story/thread in general).
I know most of these stories want you to think that AT&T and Comcast just come and plant these boxes wherever they way. I can't speak for AT&T but I can tell you that was NOT the case for Comcast. They put a power supply in our front yard and actually negotiated a contract with us to buy/rent the property it sat in.
And even if they do plant a box without your permission, chances are it's in the Right-of-way and isn't actually your property to get bent out of shape about anyway. So to the ones complaining about property value or things like that, well you were either paid to have it there or it isn't actually on your property anyway, so stop complaining (especially stop the damn complaining if you were PAID).
