The Topology Adapter needs to invoke the makeTopologicalLink API (along with the makeNPTP API) to complete the topology. Essentially, makeTopologicalLink will replicate the TopologicalLink object existing in the SONET/SDH server.

The makeTopologicalLink API needs to be invoked to instantiate the SONET/SDH Topological Link in WDM to create an association between WDM and SONET/SDH servers and provide the correlation between failures occurring in the WDM topology causing failures in the SONET/SDH topology.

makeTopologicalLink (emsName = “value“, topologicalLinkName, AendPTP, ZendPTP, displayName = “value“, className = “value“)

findTopologicalLink (emsName, topologicalLinkName)
