In this paper we present a classification, up to equivariant isomorphism, of
${{C}^{*}}$ -dynamical systems
$(A,\,\mathbb{R},\,\alpha )$ arising as inductive limits of directed systems
$\{({{A}_{n}},\,\mathbb{R},\,{{\alpha }_{n}}),\,{{\varphi }_{nm}}\}$ , where each
${{A}_{n}}$ is a finite direct sum of matrix algebras over the continuous functions on the unit circle, and the
${{\alpha }_{n}}\text{s}$ are outer actions generated by rotation of the spectrum.
