My problem turned out to be a termination problem. When using zaphfc 
together with other zap cards, it seems to be of importance in which 
order the drivers are loaded as well - At least in my case it would only 
work right if the X100P driver was loaded before the zaphfc driver.

I have got verything working now, so if you have any questions you are 
more than welcome.

You didn't write if you intended to use the ISDN cards to connect to 
ISDN lines, or if you wanted to create a setup like mine, with the 
card/cards in NT mode, acting as an ISDN switch of it's own.
