We discuss a vortex-glass-type transition occurring in YBa{sub 2}Cu{sub 3}O{sub 7{minus}{delta}} ceramics. It is suggested that the {open_quote}{open_quote}transition boundary{close_quote}{close_quote} {ital H}{sub {ital b}}-{ital T}{sub {ital b}} is a crossover line separating a nonlinear resistance state, associated with the motion of intergranular (Josephson) vortices, from a state which is characterized by a linear resistance caused by the motion of intragranular (Abrikosov) vortices. {copyright} {ital 1996 The American Physical Society.}
