A customer reports inability to send C2 message to JBC-P BFT2 type 1 URN 789456 while using a 6.5 platform with ComSat Go and visible SA. What should be checked?

• A. Currency of URN 789456, system time
• B. Platform version 6.5 only
• C. Availability of ComSat Go
• D. Status of visible SA

Answer: (A)

The key idea is that C2 messaging relies on correct addressing and synchronized clocks. The URN identifies the target in the JBC-P network, so it must be current and active; if the URN isn’t up to date, the system can’t route or apply the message to the right asset, and the send will fail. At the same time, system time on the platform must be accurate because time stamps, expiry windows, and security validations depend on a synchronized clock; a clock drift or mismatch can cause the message to be rejected or considered invalid even if the link is fine. While having ComSat Go available and the security association visible matters, they don’t resolve issues with an obsolete URN or out-of-sync time. So, verify the currency of the URN and ensure system time is synchronized.
