Question about AVM FRITZ!Box 5490 Fiber

SUNRISE now supports AVM modems for DSL & FIBER Good day - as I see it, a dogma change has taken place at SUNRISE - a total of 6 modems are now supported - (clearly) the SUNRISE Internet Boxes (DSL & Fiber) - as well as the Fritzboxes 7390/ 7490 / 7590 and the Fiber 5490 ! - So the whole thing should work perfectly (I'm looking forward to November - then we'll also have FTTH with our own OTO box - HURRA !!!!!!!!!!!!!!!!!
