　　The goal of this work is to show that lattice traveling solitary wave are solution of the general linear finite-differenced version of the linear advection equation.It extends previous works [1.2,3.4].where we analyzed a linear dispersive mechanism which results in local error focusing, referred to as the spurious caustic phenomenon.
