Signal corps veteran here:

The DNVT needs to interface through a CVSD (continuously variable slope DELTA) card to work on a POTS (plain old telephone service). This is typically accomplished through the use of a comm modem (could also be a DLTU-digital line termination unit), which requires several other cards to function as well, including the DLPMA card (diphase loop modem ALPHA).

You are partially correct in stating that the terminal is digital and POTS is analog, but that is only one reason why it will not work. Another reason is that there is no mode of dialing from which the CO (central office) can determine who it is you are trying to reach; there is no DTMF (dual tone multi-frequency) keypad, nor is there a "pulse" function, it is only through binary conversion to DTMF that you can actually tell the phone company who to call. Yet another reason, as stated above is that the DNVT is a four-wire terminal, POTS lines are but two.

If I can help in any other way, let me know. I was very very intimate with all of these systems down to the component level in my time in the ARMY.

thanks,
Zach

Wow, I worked AUTOSEVOCOM at Corozal, Canal Zone in Panama in the mid-70's, you're really bringing back memories....thanks.
