The FCC does have a residential public utilities exemption that allows the operation of Class A equipment (FCC class A) in the residential environment (normally a FCC class B case), provided the equipment is in a large room which is owned by the utility. This allows for equipment going into telco equipment rooms etc. As far as I can tell, this does not apply to those boxes that show up on the side of single family dwellings such as the fiber to the home (ftth) terminus equipment. For reasons you might quess I asked the question of the FCC - twice same answer both times.
