Cause Mapping
This appendix includes information on CTM GateWay/CORBA’s notifications, fault management, and
probable cause mapping. This appendix includes the following sections:
• A.1 Overview of Notifications, page A-1
• A.2 Resolving the Notification Service, page A-2
• A.3 Tips to Improve Notification Throughput, page A-2
• A.4 Supported Events, page A-3
• A.5 Probable Cause Mapping, page A-12
A.1 Overview of Notifications
The notification service forwards all fault notifications received from managed NEs to the network
management system (NMS). The notification service also forwards object creation, object deletion,
attribute change, protection switch, and threshold crossing alert (TCA) events. TMF 814 defines the
structure and format of attributes for all events and alarms.
The CTM server and the Operations Support System (OSS) host must have Domain Name System (DNS)
enabled in order to receive notifications. OSS clients running behind a firewall must configure an IIOP
listening port to enable the TCP connection with the notification server. CTM must configure the
notification service listening port number to allow OSS clients to communicate with the notification
service.
CTM creates the notification channel with the QoS parameters shown in the following table.
