What speed do you expect to get? 200 MBit/s?
I assume, for this the profile 35b will be used.
Which Fritz!Box model do you have?
What speed will you get with the Fritz!Box?
I don't think that the built-in VDSL modem of the HomeHub5A is capable of Supervectoring and can handle much more than approx. 100 MBit/s.
