If 447 had "stabilized" in a descent of say 5-7k fpm, there is room for an established Phugoid while descending to blank the signal in an apparent "Period". Likwise, if the aircraft had become "stable" (unacceptably) in a rotation with nose down, the airframe may have occupied an aspect that similarly blanked ACARS, seemingly in a "rhythm".
Edit, Since JD-EE has said that a signal may take 30 seconds to re-establish, we may also be looking at an interruption that is immediate, and a re-acquisition on the order of the 27-30 seconds?
This is an enormous airplane, and local velocities are distorted towards the "gentle" when we visualize. Every thing this airplane does is "slow", but occasionally only in scale.IMO
