Well OK. Now I understand the fact that shielding on both ends
sometimes _causes_ line noise instead of avoiding it. OK, thats
pretty clear now. But... :-)
1.) I still do not understand, how this noise can be triggered by
the application layer protocol (as I said, in my case: scp).
2.) Why do people sell TP-cables which are shielded on both ends
Well, before we get off topic too much... sleep well. And thanks
a lot to all of you. Things are working fine for me now.
But still some riddles remain... :-)
