There is a Linux 2.6 and mISDN HowTo:

http://rcum.uni-mb.si/~uvp00845b/

In this text the avmfritz module is used. In case of one hfc card it
should be:

modprobe hfcpci protocol=0x2 layermask=0x1f


If you want to use chan_capi, it has to be TE mode. NT mode is not
possible.

Hfc based ISDN cards will generate lots of interrupts. Interrupt
sharing will cause problems.

A solution would be to use a quadBRI card instead of the 4 HFC cards
and bristuff instead of misdn/chan_capi.
