  The paper is devoted to the study of mappings with non--bounded
characteristics of quasiconformality. We investigate the interconnection
between the classes of the so-called ring $Q$-mappings and lower ring
$Q$-mappings. It is proved that open discrete lower ring $Q$-mappings are ring
$Q^{n-1}$-mappings at fixed point. As consequence we obtain the equicontinuity
of the class of the open discrete Orlicz--Sobolev mappings with finite
distortion at $n\ge 3.$
