The G2 Communications Gateway is the core of USDD’s Fire Station Alerting System. Located at the dispatch processing center, it is the direct link between the computer-aided dispatch (CAD) system and the G2 ATX Station Controller located at each fire station.

The Communication Gateway’s design is efficient in every way. It provides simple network requirements and software updates to the “trainable” self-service pronunciation editor integrated into our G2 VoiceAlert software.

Using dynamic, flexible pathway options, the Gateway has two redundant servers for disaster recovery and backup.

The Gateway receives alert data from a dispatcher via an interface with an existing CAD host, or directly from USDD’s interactive Web-based Communications Gateway Dashboard. See a visual overview.

G2 Manual Alerting Client

Phoenix G2 Manual Alerting Client

The G2 Manual Alerting client is embedded within the G2 Communications Dashboard software. It provides a secondary (or backup) means of alerting  to fire stations should the computer-aided dispatch software fail. This helps fire agencies comply with NFPA 1221 standards.

The application can also be programmed to send messages to fire stations by time day and day of week. Examples include administrative messages, weather-related warnings, training notifications and morning or new shift announcements.

G2 Communications Gateway Benefits

  • Optimizes a community’s investment by interfacing with new or existing voice and data systems.
  • Dispatches units automatically over the agency’s radio system— without additional dispatcher actions—using clear, automated text-to-speech VoiceAlert software.
  • Uses customer’s existing redundant alerting paths, as needed, which can keep the system running during communication failures.
  • Keeps personnel advised of ongoing incidents through phone, text, email and paging alerts.
  • Monitors the health of every ATX Station Controller and G2 peripheral device within the department’s network, and reports communication failures to dispatch and support personnel via audible and visual alarms, per NFPA 1221 monitoring requirements.
  • Alerts stations as well as reserve or volunteer personnel with two-tone or DTMF pages that precede the dispatch announcement.
  • Eases IT support tasks by simplifying remote or local configuration via a Web browser.


  • Embedded secure Linux operating system
  • Redundant mirrored disk drives (RAID 1)
  • Dual 19” 1U rack mount servers
