We obtain a class of non-diagonal solutions of the reflection equation forthe trigonometric $A^{(1)}_{n-1}$ vertex model. The solutions can be expressedin terms of intertwinner matrix and its inverse, which intertwine twotrigonometric R-matrices. In addition to a {\it discrete} (positive integer)parameter $l$, $1\leq l\leq n$, the solution contains $n+2$ {\it continuous}boundary parameters.Comment: Latex file, 14 pages; V2, minor typos corrected and a reference adde
