Richard,
that terminology applies to CME (Call MAnager Express, i.e. the Call
Manager that "runs" in IOS boxen).
CCM is usually a reference to Cisco Call Manager, or the full blown Call
Manager. Even though terms are simmilar, they are not the same all over
the place.
A DN (directory number) is just that. A number that is part of your
dialplan, and that you can dial to reach some extension/phone.
A line usually refers to the ability to carry one call at one time.
So lines are mapped to phone buttons, and ... lots of fun stuff. But if
you have two lines, you may have two calls at once (usually all but one
holded)
DNs are in turn mapped to lines. Usually on a 1-1 way, but not
necesarilly. You can map many DNs to one line, or many lines to one DN.
