Description: In OSCP, some hello packets are generated periodically while others are triggered by events. Specifically, event-triggered hellos are sent upon every state change (except 'oneWay' to 'twoWay') and when a change occurs in the bundle identifier. To avoid potential system misbehavior in which hello packets would be triggered in an uncontrolled fashion, a hello hold down timer is introduced that prevents successive event-triggered hellos from being sent in too short a time interval. This object contains the minimum time between (triggered) hellos. This value must be smaller than 75% of the value of coscpHelloInterval.
