A one-dimensional integrable lattice system of ODEs for complex functions Q n (ฯ ) that exhibits dispersive phenomena in the phase is studied. We consider wave solutions of the local form Q n (ฯ ) โผ q exp(i(kn + ฯฯ + c)), in which q, k, and ฯ modulate on long time and long space scales t = ฮตฯ and x
