Abstract
The quantum discrete sine-Gordon model at roots of 1 is studied. It is shown that this model provides an example of an integrable quantum sy stem in an integrable classical background. In particular, the spectru m of quantum integrals of motions in this model depends only on the va lues of integrals of motion of a background classical system.
