VM RFOG - backup power?

At a previous property I had my ONT, router, NAS plugged into a UPS. The Openreach FTTP network was unaffected by local power outages so the WAN connection stayed up.

My new build property has VM RFOG, not HFC but it is Docsis, not XGS PON. I can order the 360 TV service.

On the edge of the estate there is a large VM VMVH1 local node cabinet with smaller power supply cabinet next to it.

If power is lost to that cabinet would that take my down regardless of my UPS? Or do the local nodes have a battery backup?
