I'd prefer broadband CPE (UL listed) with a standardized backup power connector (doesn't exist, but I can dream).

Out here, most people use this to keep CPE going when the power is out: https://www.takealot.com/gizzu-8800mah-mini-ups-dual-dc/PLID71930088?gclid=CjwKCAjwov6hBhBsEiwAvrvN6Bwdu_8uBXMXa8pC475Hd6H4Aa_fUyYeDkYg13Q-j6tkjWCGHqAFYBoC26UQAvD_BwE&gclsrc=aw.ds Nice, compact, neat package that is portable and will give reasonable backup time when needed. For CO or data centre applications, most gear should be good for 48V. If it's lower than that and you have a ton of them, you are probably better off with a protected AC source. Mark.
