This is expected, because of the patch the activation of layer 1 is delayed
until needed for the TEI request. 

So we learned that the ASCOM-NT does not like an activation of layer1,
if the activated layer1 is not used for anything. This is very similar
to my NT from the german telecom. But then i4b tries to reactivate
layer 1. This is successfull with my NT but seemingly not with the
ASCOM-NT.

Thank you!
