In order to bring the alerts to the attention of the traffic manager they will be transmitted
back to a connected UTC instation when they occur. It is a prerequisite that the MOVA
outstation be connected to a UTC instation for the alert functionality to work.
The alert API within the MOVA kernel has been used to set virtual input port bits
mova1.alerts.in.1, mova2.alerts.in.1, etc. These in turn need to be mapped back to the
UTC instation, as General Purpose reply bits GPn), where the operator can define an
action to execute on their occurrence.
To engage the alerts they should be mapped to a general purpose bit within the OTU
using the GP function as follows:-
