The interval for cwdxHeSuOnOffNotification sent by HE for
one online/offline state change if cwdxHeSuOnOffTrapEnable
is true.
If there are more than one state changes to online/offline
for a Subscriber-unit during this interval, only one
cwdxHeSuOnOffNotification is sent by HE for the first
state change to online and one cwdxHeSuOnOffNotification
for the first state changing to offline if
cwdxHeSuOnOffTrapEnable is true.
This is to avoid too many notifications sent for a
SU online/offline state changes during a short period
of time.
If the value is 0, then cwdxHeSuOnOffNotification will be
sent for every state change to online/offline for a
SU if cwdxHeSuOnOffTrapEnable is true.
This object's value will be retained even if the
cwdxHeSuOnOffTrapEnable value changes. Thus disabling
notifications will not result in this object's value
being reset tot he default value.
The default value is 600 seconds.
