A simple analog phone should work.  If you get dial tone you have an 
analog line.  I carried a cheap analog phone with me for phone line 
testing.  I don't recall ever trying it on a digital phone line 
though.

I've seen digital lines using RJ-11.  That was at my previous 
employer where the office I was at had digitial and analog lines.
