The design is based on the HFC-SP chips by Cologne Chip, see http://www.colognechip.com/isdn/controllers/frame-hfc-sp.htm > As far as I got it I have to write a new hardware-level driver for the > isdn4linux subsystem, is that right ? Is anyone aware of special problems > I have to focus ? Interfacing the ISDN chips with the MPC8xx bus might be an issue (timing). That's why we selected a PCMCIA based design (although we won't use a PCMCIA card).
