Use the Outstation Form to specify whether the dial out frequency can be promoted for an individual PSTN outstation (see Temporarily Increasing the Frequency with which an Outstation is Called).
You can also use the Outstation Form to define Dial In Overactive settings. These allow you to configure the outstation so that if it dials in too frequently within a defined time period, an alarm is raised or an event is generated (see Configuring an Outstation to Raise an Alarm if it Dials In Too Frequently).
