Message Pattern
Success Examples
The device detects the condition and generates GBCS event/alert code 0x8F22.
The device transmits a GBCSResponse/DeviceAlertMessage to the DSP via the WAN. Payload contains alert code and timestamp only (Generic Alert Structure).
DSP authenticates the GBCSResponse against the device certificate and validates the alert content.
DSP delivers the alert to the relevant Known Remote Party. The DUIS Response (sr:Response) wraps the raw GBCS payload in sr:GBCSPayload (base64).
The DCC User runs the received DUIS Response through the Parse tool, which decodes the GBCS payload and produces an ra:GBCSResponse (MMC) document containing the structured alert data.
