2.4 The CAP Alert Handler Interface
Uses
The CAP Alert Handler interface listens for traffic from GSS and
processes the Common Alert Protocol (CAP) messages that it
receives. Each box must be manually configured to receive these
messages from GSS
—Creating a CAP Alert Handler interface
won’t ensure that the FlexGate receives alerts. Each handler can
be customized to trigger only when certain conditions are met. The
currently implemented handler only handles Earthquake
messages. If a CAP alert is received that matches the conditions
set, the specified Action Plan will be triggered. (See Chapter 6:
Creating and Using Action Plans for more information.)
Depending on the Alert Type selected, different fields will be
provided for the user to specify the conditions for activation.
For Earthquake Alerts, the box’s latitude and longitude must be
entered in the Admin page of the webconfig. These values are
used to determine the expected intensity and time until impact
(see Figure 2-3).
