The pre-provisioned link connection management community is used to assign transport entities (link connections or connection termination points) to a caller and to control and update the available capacity of the linking entity (link or link end) that contains the transport entities. The available capacity of the linking entity contains all the unassigned transport entities. This community should be used in the case where transport entities have already been provisioned inside the linking entity using the pre-provisioned adaptation management service (See Recommendation G.853.8). The capability of having pre-provisioned transport entities is available in technologies such as SDH or WDM. Enterprise community actions covered by this specification: - COMMUNITY pre-provisioned linkConnection management; - assign transport entities; - de-assign transport entities; - report transport entities change.
