From Pai himself
We find that the current speed benchmark of 25/3Mbps remains an appropriate measure by which to assess whether a fixed service is providing advanced telecommunications capability. We conclude that fixed services with speeds of 25/3Mbps continue to meet the statutory definition of advanced telecommunications capability; that is, such services “enable users to originate and receive high-quality voice, data, graphics, and video telecommunications.”
While I doubt you could do all those things on 25/3Mbps. You can definitely not do any two of those at the same time.
