Globalstar Service Alerts
Service alerts are sent on the Control port or queued (if only
the Data port is connected and in use) whenever a service
parameter changes:
• Fades — Gateway/satellite coverage is lost for any
reason.
• Acquisition — Gateway/satellite coverage is acquired
(entering service, leaving service, or changing Service
Providers).
• Roaming status — when the modem “roams” onto a
Gateway outside the home service area (see your Service
Provider for the scope of these areas).
