isdn-problem

[Stephan Kiesel]

Hi,
I'm debian newby and have set up a linux box running debian 2.2  (potato)
with kernel 2.2.17. Furthermore I have set up an isdn interface teles16.3
non-pnp running with hisax  on ippp0.
The following problem occured:
On starting the system and the isdn services, my ippd0
establishes a connection to my isp nameserver (IP-address:port 53) every 10
minutes without any user activity. I have configuration files in /etc/isdn
but no idea which flag to set. Can anybody help?
thx stephan
