This ACTION adds, or schedules the addition of TTPs to an existing multipoint trail connection in the layer network. The TTPs are identified directly or indirectly by an interface within which the vcLayerNetworkDomain or vpLayerNetworkDomain manager selects a point. The indirect case may use an optional descriptor providing VPI/VCI. An error condition is raised if the atmTrail is incorrect, the termination points are incorrect, already used, do not have matching traffic descriptors of the existing trail, or if vcLayerNetworkDomain or vpLayerNetworkDomain is unable to provide sufficient bandwidth. Input: Id of atmTrail, descriptors of the endpoint: interfaceId (serverTTPId), and VPI/ VCI. . If deferred request: requestServiceTime. Output: Ids of the atmTrail and added TTPs. Errors: protocol-specific addressing errors, incorrectTerminationPoints, TTPDisabled, TTPLocked, TTPConnected, non-matchingDescriptors, operationFails. Results: Creation or association of TTPs to the atmTrail. A response indicating partial addition (indicating both successful and unsuccessful end points) will be generated in cases where addition of endpoints to a multipoint atmTrail neither completely succeeds (all endpoints additions succeed), nor completely fails (no endpoint additions succeed).
