Is this saying that if I had one PRI, that I couldn't do both analog and
ISDN calls off it assuming I have digital modems?

Your "and/or" is also a bit confusing. Basically, my question is as I
asked above. Can each PRI handle both ISDN or analog calls by determining
the call type during call setup, or does one have to configure this PRI
only for analog, and this one only for ISDN, etc...?
