Inter-board Alarm Suppression

Inter-board Alarm Suppression

The inter-board alarm suppression means that, when services are configured between two boards on the same NE, the service alarm generated by the source board suppresses the service alarm generated by the sink board. The equipment supports the alarm suppression between a line board and a tributary board, and between a line board and a data board.

Figure 1-8 shows the inter-board suppression relationships among common alarms.

Figure 1-8  Inter-board alarm suppression relationships

If an alarm above the arrow is generated at the service source, and the alarm below the arrow is generated at the service sink, the alarm above the arrow suppresses the alarm below the arrow. In this case, you can focus on the alarms at the service source during troubleshooting.
