In the spirit of continued study of general plasma wave properties we investigated the boundary problem with the simplest form of electric field pulse at the edge x=0 of half-infinite uniform plasma slab with Maxwellian electron distribution function. In the case of longitudinal electric field pulse its traveling velocity is essentially other than in the case of harmonic waves; there is also no back response. In the case of transverse field pulse there takes place the bimodal propagation rate of the non-damping fast pulse signal and non-damping weak slow sign reversed pulse signals; some very weak response (echo) arises with a time delay in the near coordinate zone of formation of the asymptotical regime.
