I was in South Bangalore two weeks ago and in a housing layout I saw the same terminal boxes mounted on a GI pole. It was connected to the the underground cable. Looks like they will launch at the same time in Bangalore, assuming they are doing similar work everywhere in the city.
In my apartment, the main cable is not yet connected to the underground network yet. I think it BBMP approval for cutting the roads are not being given for now. That could be a reason for delay too
