Looks like all the cabinets on my exchange (LCAOR) are going to be this type of cabinet. I've seen 8 or 9 locations in the last week that have had this cabinet installed.
Our estate has had at least 3 cabinets installed this week and they are all the same as the one pictured in your original photo.
As an aside ... my particular cabinet now has power as it emits a slight hum and is warm to the touch on one side.
How long was it after the cabinet was installed that the power seemed to get power? - ours was installed Monday by contractors working for Openreach - I was wondering when Openreach themselves would come and start installing stuff in it.
Thanks,
Ian
