Thanks for the info. According to this page at Init7 the Fritzbox 5530 is only recommended for P2P, i.e. not P2MP (XGS-PON).
I also heard that XGS-PON connections cannot be ordered from any non-Swisscom provider at the moment.
There are complaints to the ComCo from some providers against Swisscom.
This thing seems to be getting complicated for XGS-PON customers.
Does anyone have more information about this? Greeting
