This ACTION sets up, or schedules the setup of a point-to-point or a multipoint connection between non-connected TTPs in the layer network. The TTPs are identified directly or indirectly by an interface within which the vcLayerNetworkDomain or vpLayerNetworkDomain selects a point. The indirect case may use a set of optional descriptors providing VPI/VCI, traffic descriptors, QOS, etc. An error condition is raised if the termination points are incorrect, already used, do not have matching traffic descriptors, or if vcLayerNetworkDomain or vpLayerNetworkDomain is unable to provide sufficient bandwidth. The routing information may be either explicitly stated in the ACTION or the ACTION can point to an existing instance of the atmRoutingProfile object class. The routingDetails are a set of topological routing constraints that can be applied to a trail during setup. The routingDetails are a list of objects (such as Links, Subnetworks, existing connections) and their use in routing (exclude, mandatory, preferred, same route, diverse route) and the maximum number of hops. The connection shall not be established if the routing criteria cannot be met. If maxHops is specified, the connection shall not be established if the maximum number of hops is exceeded. Objects (such as atmSubnetwork, atmLink, or managedElement, etc) may be referenced by the routeDescriptionList as being excluded, mandatory, or preferred. If an object is described as mandatory it must be used in setting up a new connection. An attempt must be made during setup to include an object described as preferred. An excluded object must not be used in a connection. Connection type objects (such as atmTrail, atmSubnetworkConnection, etc) may be referenced by the routeDescriptionList as same route or diverse route. A new connection being created shall follow the same route as a sameRoute referenced object. A new connection must follow a different route than a referenced object referred to as diverseRoute. Input: Connection Type (point-to-point, multicast, merge, multicast/merge, full multipoint), Descriptors of the endpoints: interfaceId (serverTTPId), VPI, VCI, trafficDescriptors, and QOS. Optionally a list of identifiers for objects (atmSubnetwork, atmSubnetworkConnection, atmLinkConnection, other) to be used for route selection. If deferred request: requestServiceTime. Output: Ids of new atmTrail and associated TTPs or Id of the deferred atmTrailRequest for deferred request. Errors: protocol-specific addressing errors, incorrectTerminationPoints, TTPDisabled, TTPLocked, TTPConnected, non-matchingDescriptors, operationFails. Results: Creation or association of TTPs and an associated atmTrail. A response indicating partial setup (indicating both successful and unsuccessful end points) will be generated in cases where a multipoint atmTrail set up attempt neither completely succeeds (all endpoints succeed), nor completely fails (zero or one endpoints succeed).
