It is shown that the presence or the absence of a soliton excitation threshold and the threshold values depend on the character of the excitation distribution at the initial time moment. A study is made of the time evolution of an excitation given at the initial moment as a hyperbolic secant, in form of a rectangular step, and as a decreasing exponential.
