Question: Upon receiving a termination instruction in an MCPTT interworking scenario with LMR, what action does the IWF floor control server take regarding timers T1 and T2 if their respective dual timers (T11 and T12) are running?
Option 1: Sets the value of timer T1 to T11's value and starts T1, and sets the value of timer T2 to T12's value and starts T2.
Option 2: Stops timers T1 and T2 immediately without modifying their values based on T11 and T12.
Option 3: Resets timers T1 and T2 to their default values without starting them, regardless of T11 and T12's states.
Option 4: Delays setting and starting T1 and T2 until T11 and T12 have expired.
Explanation: This action ensures a synchronized termination process, aligning the single and dual floor control operations' timelines. By setting T1 to T11's value and T2 to T12's value before starting them (if their duals are running), the IWF floor control server maintains consistency in managing the end of RTP media and the stop talking indicator, respectively, across both standard and dual floor control scenarios. This coordinated approach is crucial for seamless interworking between MCPTT and LMR systems.
