How do I just turn dnd off

Thanks - that's what I've always done, but I never knew what "Focus" means or whether calls would ring. After putting this question in, I just created a custom DND-Off focus. I have to drill down to select that "Focus" but at least I "know" it will allow any phone calls I may be expecting but whose numbers I don't know. (You pretty much never know what number an incoming call from a business will be.) In order to "Allow All Calls" I had to proceed PAST the "Select contacts to allow calls from" in Settings.

(I have another Focus that accepts calls from my family.) If I can get used to "DND-Off" focus saying it's "On" it might work.

In the meantime, does anyone happen to know what a non DND "Focus" means functionally if there are no Focuses set up at all?
