This scope of this standard is to define information models and to specify the basic set of management functions needed to support Connection Management. The focus of this standard is on the point-to-point, Reconfigurable Lease Circuit Service (LCS). The Reconfigurable LCS may be offered by one or more service providers (SP) and many be controlled by the service customer (SC) with different levels of visibility. The LCS is defined between a single SC and a single SP.
