No. You only have to buy digital modem cards if you want to support analog
modems calls. Either way you always get ISDN functionality.

Per channel per call. Your PRI signals to the PM3 whether the call is a
analog call or a digital call. The PM3 either answers it as a ISDN call or a
analog call (if you have modem cards).
So if you have 2 8-modem cards you could have 16 analog calls and 7 ISDN
calls all running at the same time. Or you could have 23 ISDN calls. Just
remember that the number of 8-modem cards you have is the highest number of
analog calls you can have.
