Appendix A Notifications, Fault Management, and Probable Cause Mapping Resolving the Notification Service CTM sets the RejectNewEvents administration property of the channel to true, as defined by the TMF. Every notification that CTM generates has the QoS parameters listed in the following table. These parameter values are defined by the TMF and cannot be changed. Table A-2 QoS Parameters for Notifications Parameter Value EventReliability BestEffort Priority DefaultPriority Timeout 30 m

Appendix A Notifications, Fault Management, and Probable Cause Mapping Supported Events To improve throughput, you should receive the event and forward it to another thread for processing. For example: void push_structured_event(StructuredEvent notification) { try { some_other_thread_queue.addNotification(notification); } catch (Exception ex) { // catch all exception and ignore ex.printStackTrace(); } } Caution As shown in the example, you must catch all exceptions, or you will stop rece

If there is an alarm on an STS/VC4 CTP utilizing all ports of a DS1/E1 card, the alarm is reported with the containing PTP as port 127. If an STS/VC4 SNC exists with one of the drop CTPs of the SNC using all ports on a DS1/E1 card, and if there is an alarm on the STS CTP, CTM reports the port number of the containing PTP as 127.
