## Abstract In the paper bilateral shifts are studied which generate factorizations of unitary couplings (in the system theory they play the part of channels). Subspaces of __L__^2^(π”Ž), reducing the multiplication operator by __e__^__it__^, are investigated in the channel language. New criteria for
