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 managedElementManager::ManagedElementManager_I:: getAllActiveAlarms interface
to request all current alarms on the ME.
2. Uses the equipment::EquipmentInventoryMgr_I:: getAllEquipment interface to request all
existing equipment on the ME.
CTM returns a list of EquipmentHolder_T objects with detailed information about equipment
holders and equipment on the ME.
3. For the equipment information retrieved in EquipmentorHolder_T object, uses the
equipment::EquipmentInventoryMgr_I:: getAllSupportedPTPs interface to request all supported
PTPs on the equipment.
CTM returns a list of TerminationPoint_T objects with detailed PTP information, such as SDH or
SONET port, admin state, service state, line code, frame format, and so on.
4. For each TerminationPoint_T object, executes the “NMS Resynchronizes Information Specific to
TerminationPoint” use case.
5. Uses the managedElementManager::ManagedElementManager_I:: getAllSNCs interface to
request all SNCs originating, terminating, or passing through the ME.
CTM returns a list of SubnetworkConnection_T objects with detailed SNC information, such as
layer rate, SNC state, SNC protection state, a-end CTP, z-end CTP, and so on.
6. Uses the protection::ProtectionMgr_I:: getAllProtectionGroups interface to request all protection
groups created on the ME.
CTM returns a list of ProtectionGroup_T objects with detailed protection group information, such
as 1:1, 1+1, or 2F-BLSR; revertive or nonrevertive; and so on.
Ends When The NMS retrieves all ME-specific information.
Exceptions Refer to the exceptions thrown by the individual interface method.
Post Conditions The NMS synchronizes information about an ME with CTM.

Information Detail
Name The NMS retrieves CTM information specific to the termination point.
Summary The NMS retrieves all loopback and threshold information for PTPs and CTPs used by the SNC.
Actor(s) NMS.
Preconditions The NMS obtains references to ManagedElementMgr_I, MaintenanceMgr_I, and
PerformanceManagementMgr_I interfaces. The NMS also obtains a list of PTPs.
Begins When The NMS sends a request to retrieve all threshold and loopback information on a PTP and on any in-use
CTPs. The NMS identifies the name and type (PTP/CTP) of the TP for which to retrieve information.
