Abstract
Flexibility is achieved in provisioning communication rings with an integrated DCS that allows any port that is connected to a line interface unit within the integrated DCS to be coupled within the integrated DCS—pursuant to software controlled provisioning—to any other port that is connected to a line interface unit within the integrated DCS. This is accomplished by merging the cross connect fabrics of the ADM portions of the integrated DCS with the cross connect fabric of the DCS portion of the integrated DCS, by incorporating at least some of the switching controls of the ADMs in the ADM portion of the integrated DCS in the controller of the DCS, and by insuring that the SONET K-bytes can be passed by the controller of the flexible integrated DCS from any line interface unit to any other line interface unit.
