Question: What happens if the Core Network (CN) doesn't receive a RESET ACKNOWLEDGE message from the Radio Network Controller (RNC) after sending a RESET message, in terms of repeating the Reset procedure?
Option 1: The CN stops the procedure immediately and informs the maintenance system.
Option 2: The CN repeats the entire Reset procedure once more before stopping.
Option 3: The CN repeats sending the RESET message up to a maximum of "n" times (where n is determined by the operator) before potentially informing the maintenance system.
Option 4: The CN switches to an alternative protocol for communication with the RNC.
Explanation: This option correctly reflects the procedure outlined, where if the CN doesn’t receive a RESET ACKNOWLEDGE within the specified period (TRafR), it will repeat the entire Reset procedure. This repetition is limited to a maximum of "n" attempts, after which the process is halted and other actions (like notifying the maintenance system) may be taken. This demonstrates an understanding of error handling and retry mechanisms in telecom network signaling.
