Answer
DLS IR mandates CPDLC capability for aircraft operating above FL 285. If such capability does not exist (aircraft is not equipped or crew is not trained) and if the aircraft is not exempted, flight plan should indicate flight profiles below FL 285 within the airspace where the DLS IR is applicable.
