   GES initiates a DATA-2 ACARS transmission (uplink), but receives no acknowledgement from the SATCOM.
   

   1. Therefore, the SATCOM Link was lost at sometime between 1707:48 and 1803:41.
   2. There is no evidence of a cockpit-initiated manual Log-Off of the SATCOM.
   3. Note that even if the on-board ACARs equipment was failed, disabled or powered down at this time, it would not prevent the SATCOM from acknowledging the ACARS-related P-Channel transmissions from the GES.
