Remember we used the periodic boundary condition, just because we have decided to ignorate the effect of the boundary, so you of course can not get any results about "travelling beyond end points". Anyway, in most semiconductor textbook when we consider interaction btw. phonon with electron, photon etc. we never consider the end point case.
And you said "it is in it's second exited state", "it has two phonons", could you tell me who is the "it"??

The single-atom harmonic oscillator is what is called a "limiting case" for the extended wave. The extended wave comes about because the atoms are coupled to each other by elastic forces. If the two atoms are connected by an elastic force, one atom being much more massive than the other, then the light atom can be considered a harmonic oscillator by its.
