Alert received and validatedDSP (internal)
DSP authenticates the GBCSResponse against the device certificate and validates the alert content.

No DCC User deliveryDSP (internal)
This alert is not delivered to a DCC User. RTDS GBCS HEX is therefore sufficient for coverage; DUIS Response and MMC Parse examples are not required.
