ISDN: change hisax to capi (FritzPCI card)

[Ekkard Gerlach <eg@liburg.com>]

Hello community, 

I've lenny with 2.6.32 bpo installed and I need to install capi for FritzPCI
because of fax. 

First I don't find any  fritz-fcpci-src-2.6.32.tar.bz2 . Where can I get it? 

Second I need help to change my hisax driver installation to capi. I installed with 
      aptitude install isdnutils-base isdnutils isdnlog-data 
and my ippp0 and ippp1 for dialin and dialout works fine. Now I need to 
change to capi.
