The indices of inseparability $i_0,i_1,...,i_{\\nu}$ of $L/K$ were defined by Fried in the case char$(K)=p$ and by Heiermann in the case char$(K)=0$; they give a refinement of the usual ramification data for $L/K$. The indices of inseparability can be used to construct \"generalized Hasse-Herbrand functions\" $\\phi_{L/K}^j$ for $0\\le j\\le\\nu$. In this paper we give an interpretation of the values $\\phi_{L/K}^j(c)$ for natural numbers $c$.
