Interphone coverage in crew rest areas is set up to ensure direct, two-way contact with the flight deck and other crew members even when the rest spaces are in use. In the OFCR (Onboard Flight Crew Rest) there are two interphone stations, and in the OFAR (Onboard Flight Attendant Rest) there are two as well. Adding them together gives four interphones in these two areas. This arrangement allows a crew member to call the cockpit or other sections without leaving the rest area, which supports timely communication during rest periods and potential emergencies.
