We propose a generalization of the Baxter T-Q relation which involves morethan one independent Q(u). We argue that the eigenvalues of the transfer matrixof the open XXZ quantum spin chain are given by such generalized T-Q relations,for the case that at most two of the boundary parameters {\alpha_-, \alpha_+,\beta_-, \beta_+} are nonzero, and the bulk anisotropy parameter has values\eta = i \pi/2, i\pi/4, ...Comment: 14 pages, LaTeX; amssymb, no figure
