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

The makeNPTP API needs to be invoked to instantiate the SONET/SDH PTP 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.

During the invocation of makeNPTP two other objects are automatically constructed in the WDM topology:

  • ClientInOcnPort

  • ClientOutOcnPort


    Relationship between these objects and corresponding PTPs are automatically created in the makeNPTP API, but a relationship needs to be created between these ports and the corresponding FiberLinks connecting them to Transponder Ports.

    makeNPTP (neName, ptpAid, cardAid, displayName = “value“, className = “value“, relateEquipment = “value“)

    findNPTP (neName, ptpAid)


    findPTP is deprecated. Use findNPTP instead.
