The type of notification shall be indicated by the parameter Notification Type of the DIRECTIVE_Notify.indication primitive. A DIRECTIVE_Notify.indication primitive delivered to the user is translated from a directive notification signal generated by FOP-1 (see 3.2.2.2.3). The Notification Types of the DIRECTIVE_Notify.indication primitive defined here shall also be used as the Notification Types of the directive notification signal generated by FOP-1. Table 4-2 shows the Notification Types of the DIRECTIVE_Notify.indication primitive defined for COP-1. For other parameters used by the DIRECTIVE_Notify.indication primitive, see reference [3]. Table 4-2: Notification Types for DIRECTIVE_Notify.indication Notification Type Accept Response to Directive Reject Response to Directive Positive Confirm Response to Directive Negative Confirm Response to Directive Asynchronously from a Directive requested by the user, FOP-1 shall return either an ‘Accept Response to Directive’ notification or a ‘Reject Response to Directive’ notification. This indicates whether or not FOP-1 will try to execute the Directive. If a ‘Reject Response to Directive’ notification is returned, then no other notifications will be returned for the requested Directive. After each ‘Accept Response to Directive’ notification, but asynchronously from that notification, FOP-1 shall return either a ‘Positive Confirm Response to Directive’ notification or a ‘Negative Confirm Response to Directive’ notification, referring to the Directive. This indicates whether or not COP-1 (including FARM-1 for Directives requiring receiving-end action) was able to complete the execution of the Directive.
