I'm guessing 1 or more settings are for low voltage. Some PBXs and some SIP to loop start converters only have 24-30 volts on hook. The Panasonic 4-line cordless system has provision, and I believe some of the AT&T multiline sets have the same capability, as well.
When I was young, I was Liberal. As I aged and wised up, I became Conservative. Now that I'm old, I have settled on Curmudgeon.
