Unheard of in the northeast. I know some cable systems somewhere in the USA have all their span power supplies having generators in them, someone has to buy these »www.alpha.com/Products/Cable-Bro···erators/ . I think I read in some states PUC/PSCes required cablecos to sign up as ILECs to offer phone service, and the law mandated 24/7 uptime/backup power. Comcast Digital Phone (not Voice) and RCN were/are line powered phone service.
Also unheard of in the more rural areas of the country. Maybe the densely populated areas have this luxury but I'd guess 75 or more percent of the country doesn't have back up power. My Verizon wireless has a big cat gen-set so my cell phones and Vz Home Connect work ok if I can keep my generator on.
