Question: What determines the presentation indicator sent by the MSC to a CNAP (Calling Name Presentation Additional Feature) subscriber's MS (Mobile Station), in scenarios involving calling name information?
Option 1: Solely the presentation indicator in the calling line information, if available.
Option 2: A combination of the presentation indicators in the calling line information, calling name information, and the response from the name database (if applicable).
Option 3: The structure of the name database exclusively.
Option 4: Always defaults to restricting the calling name for privacy.
Explanation: This is because the MSC's determination process for the presentation indicator involves evaluating multiple sources to decide how to present the calling name to the subscriber. These sources include any available indicators from the calling line information, the calling name information itself, and potentially, the response received from querying a name database. This combined approach ensures a more informed decision about whether to restrict or allow the display of the caller's name, based on the most comprehensive set of available privacy preferences.
