Alerting feature
The Alerting feature configuration is divided into two parts:
• general parametrization available for all alerts
• alert specific parameters.
The generic configuration parameters are:
• LIP inclusion, giving the possibility to include alert statuses into LIP messaging
• Acknowledgement allowed from all numbers.
The alert specific parameters are:
• IO line bound to alert
• Alert handling: None, SDS-1 or SDS-4 messaging when alert condition occurs
• Handling including one shot messaging, continuous - until alert condition is removed, until successful sending
or special acknowledge required before clearing the condition
• Encoding of the message (SDS-4)
• Status value or SDS-4 payload
• Lifetime of the alert
• Destination address into which the alert messages are sent.
TETRA Terminal Programming Tool (TPT)
The Alerting feature can be configured using the Mobile Parametrization view shown in Figure 7.
