I understand that you should be ok with broadband staying up with

of their own etc?


I'm on VDSL, and the BT cabinets with the DSLAM/MSAN have battery
backup.


For how long?

Cover a switching dropout or auto recloser trip/reset? Cover 10 mins
whilst DNO engineer drives between manual switches to restore supply
via a different route?

36 hours whilst they replace snapped poles and switch gear bought
down by an ice storm?
