This table contains the list of Delay Measurement threshold configuration values for DM Performance Monitoring. Instances of this managed object are created automatically by the Flow when the Flow creates an instance of OsSoamDmCfg. The main purpose of the threshold configuration table is to configure threshold alarm notifications indicating that a specific performance attribute is not being met. Each row in the table represents a Delay Measurement session threshold set for the defined Flow. This table uses five indices. The first three indices are the indices of the Maintenance Domain, MaNet, and Flow tables. The fourth index is the specific DM session on the selected Flow. The fifth index is the specific threshold set number. Rows in this table are not created automatically. A row is created in this table to set up a threshold set on a configured Flow that has a configured DM session. At least one threshold set is necessary for NE SOAM PM compliance. A second threshold set on the NE is desirable. More than two threshold sets on the NE can be configured if supported on the NE. All the objects in the row have a default value that disables the particular threshold measurement. In order to enable a threshold measurement the particular bit in the osSoamPmDmThrPrflEnable object is to be set to '1' and the selected threshold measurement is to have a threshold value configured. Non-configured threshold measurements are disabled by default. The writable objects in this table need to be persistent upon reboot or restart of a device.
