I have a SuSE 6.3 system with the updates to ISDN4Linux.  The ISDN T/A is an
internal PCI card based on the HFC chipset.  It is detected by the driver
and everything loads correctly at boot up.  I have set up the ISDN
configuration files using YaSt and checked them manually.  My ISP uses PAP
authentication and pap-secrets seems to be configured correctly.  I can
connect using an analogue modem without difficulty.  When trying to
establish an ISDN link,  the system dials the number,  a connection is
established briefly,  and then it appears the remote server hangs up.  The
relevant extract from the log files follows below (i enabled debug and +pword),  and I would be grateful
for help,  as I have tried everything I can think of to fix this problem,
and I don't know what to do next.

Thanks!

Grant.
