Stefan, Peter,

Thanks for the replies guys.

I have looked at the web page and will work on it over the weekend.

My next step will be to find out hoe the CO lines connect, but that's
another project.

Regards

Dave

Yes, as I wrote, I was reading to fast...
However, termination may be done by simply connecting a terminated
multiplug to the card and power is only needed for phones without own
power source. I have e.g. a Siemens Gigaset cordless phone connected to
my internal port, so I need no power.
But anyway, I believed, David was writing about ISDN monitoring, so my
answer was inadequate, I confess.
May we PLEASE leave out the tar and feathers? Only this time? :-)

Regards,
   Stefan
