If you mean the AVM card the answer is that you write a Brand X Unix/Linux
(you didn't say) device driver which includes a software emulation of the
digital signal processing in V.21 and V.29 modems, together with HDLC
framing and an EIA Class 1, 2 or 2.0 interface, and which looks like an
asynchronous serial port to the applications.

This is quite a major project and I don't expect to see an open source
one in the near future.

Alternatively you run it on Windows, where the supplied drivers do all
of this, and use a Windows fax program instead of Hylafax.

You can replace V.29 by the 14,400 bps equivalent.

I don't think there are any realistic Hylafax solutions for 3.1kHz 
audio fax over ISDN which use internal cards.  You will need to use
an external device which emulates an analogue fax modem, or plug an
analogue modem into an analogue port on the adaptor.
