C.1 Use Cases to Resynchronize the NMS from the EMS
Description The NMS does the following to request information from the CTM GateWay/CORBA interface:
1. Uses the emsMgr::EMSMgr_I:: getAllEMSSystemActiveAlarms interface to request all EMS
alarms.
2. Uses the emsMgr::EMSMgr_I:: getAllTopLevelSubnetworks interface to request all multilayer
subnetworks in CTM.
CTM returns a list of MultiLayerSubnetwork_T objects with detailed information about a
multilayer subnetwork.
3. Uses the emsMgr::EMSMgr_I:: getAllTopLevelTopologicalLinks interface to request all
topological links across multiple multilayer subnetworks.
CTM returns a list of TopologicalLink_T objects with detailed information about a topological
link.
4. For each MultiLayerSubnetwork_T object, CTM uses the
multiLayerSubnetwork::MultiLayerSubnetworkMgr_I:: getAllManagedElements interface to
request all MEs that belong to that multilayer subnetwork.
CTM returns a list of ManagedElement_T objects with detailed information about an ME.
For each ManagedElement object, executes the use case “NMS Resynchronizes Information
Specific to a Managed Element.”
5. Uses the multiLayerSubnetwork::MultiLayerSubnetworkMgr_I:: getAllVLANs interface to
request all VLANs associated with the multilayer subnetwork.
Ends When The NMS retrieves all CTM information.
Exceptions Refer to the exceptions thrown by the individual interface method.
Post Conditions
• The NMS synchronizes with CTM.
• The NMS registers with CTM to retrieve notifications related to changes in the managed object on
CTM, new alarms, and TCAs.

Information Detail
Name The NMS retrieves CTM information specific to the ME.
Summary The NMS retrieves all PTP, CTP, SNC, and protection group information for the specific ME.
Actor(s) NMS.
Preconditions The NMS obtains references to ManagedElementMgr_I, EquipmentInventoryMgr_I,
MaintenanceMgr_I, ProtectionMgr_I, and PerformanceManagementMgr_I interfaces. The NMS also
obtains the ME name.
Begins When The NMS sends a request to retrieve all information about an ME. The NMS identifies the name of the
ME for which to retrieve information.
