Peculiar is talking about those old phones that would have all of the letters on only the numbers. So 2 would mean A, B, or C; 3 would mean D, E, F; and so on. Puncuations (like the period) would be under 1. I should also be realized that while most of the numbers equate to 3 letters, 7 and 9 have 4 letters.
