Performance and inventory application programming interfaces (APIs) do not retrieve any information
Note
for out-of-service NEs.
The gateway authenticates the northbound OSS. Once authenticated, the OSS can perform operations
and receive alarm notifications.
CTM GateWay/CORBA uses jacORB 2.1.3.7. The corresponding standard is Object Management Group
(OMG) CORBA 2.3.
1.2 CTM GateWay/CORBA Fault Management
CTM GateWay/CORBA forwards all the fault notifications received from managed NEs and all CTM
alarms to the network management system (NMS) through the notification service. Information about
the notification service is available on the OMG website at www.omg.org.

The NMS retrieves all active alarms on the EMS and on managed element objects. The NMS filters
alarms based on probable cause, perceived severity, and managed element name.
1.3 Overview of CORBA Services
CTM GateWay/CORBA uses two CORBA services—naming service and notification service. The
naming service is required for CTM GateWay/CORBA to function. If the notification service is not
available, alarm and event notifications are not forwarded to the OSS. By default, the naming and
notification services are installed on the CTM server during the GateWay/CORBA installation. However,
