NOTE 6
active – unacknowledged: V
active – silenced: S
active – acknowledged or active: A
active – responsibility transferred: O
rectified – unacknowledged: U
normal: N
NOTE 7
Used for proprietary alerts defined by the manufacturer. For standardized
alerts this should be a null field.
NOTE 8
The alert identifier is unique within a single alert source. The alert identifier is
a variable length integer field of maximum a 7-digit integer. It identifies the
type of the alert, e.g. a “lost target” alert. Number range 10000-9999999 is
reserved for proprietary alerts. Alert Identifier examples: “001”, “2456789”,
“245”.
NOTE 9
The alert instance identifies the current instance of an alert to distinguish
alerts of the same type (Alert identifier) and from the same source (e.g.
dangerous target). Alert instance is maximum a 6-digit integer from 1 to
999999. The number of alert instance can be freely defined by the
manufacturer as long as it is unique for one type of alert (alert identifier). It is
not permitted to modify the alert instance within a life cycle of a distributed
alert (from ‘active-unacknowledged’ state until ‘normal’ state is reached). It
can be also a null field, when there is only one alert of that type.
NOTE 10
The revision counter is the main method to follow an up-to-date status. The
revision counter is also unique for each instance of alert. The revision
counter starts with 1 and the step for an increment is 1. The count resets to
1 after 99 is used. The revision counter increments on each change of
content of any field of the alert.
NOTE 11
The escalation counter is presenting the number of alert escalations after
time expiration during the state active-unacknowledged. The escalation
counter starts with 0 and the step for increment is 1. The count resets to 1
after 9 is used. The alert escalation can be the escalation from warning into
warning (activation of audible signal only), the escalation from warning to
alarm, or the escalation from alarm to alarm with the activation of backup
navigator alarm.
