Hey Don,

you are great! Thanks for your help, it worked. I can load hfcmulti and it
is list under <lspci -v> for the HFC-E1 card and also <misdn_info> founds
the card. I'm very happy that it is working again after it broke. :-)

But the problem with lcr is still there:

@Andreas:
Thanks, I didn't know that. I prefer to work with mISDN & LCR & Asterisk
because I have these installed and if it is possible to run OpenBSC with
mISDN, mISDNuser, lcr and Asterisk I want to try this. Do you know if it is
required to use lcr with gsm for connect OpenBSC and Asterisk if I don't
use sip?



Regards and thank you for your help.
Ellen
