The translation table is (at least on the phones that I have seen so far ;-): abc -> 2 def -> 3 ghi -> 4 jkl -> 5 mno -> 6 pqrs -> 7 tuv -> 8 wxyz -> 9

The translation is done automagically by pressing the button with the
letter  engraved.
It is mostly used for vanity numbers.

The North American standard actually omits 'q' and 'z'; 7 is just "prs"
and 9 is just "wxy". I've seen some phones put "qz" on the 0 key, but
that was never part of the standard. There's a good overview of keypad
layouts here:

Hm, every cell phone I've had in the last 7 years has pqrs on 7, and wxyz on 9. So do both my land line phones. At this point, I'd say this has become the de facto standard. I do recall "qz" on the 0 key back in the early 90's, but as noted, it didn't last.
