Narrative:

Flight had obtained oceanic clearance normally from new york oceanic; and had entered nat track at joboc; fl 340 proceeding to 41n060w. At approximately XA02Z; the flight crew heard a chime and responded to a cabin call from flight attendants. About ten minutes after the conversation had ended on the interphone; the captain noticed the upper EICAS screen had white 'ATC' displayed. ATC key on the FMS was selected and an ATC uplink was present: 'climb to reach fl 350 by XA17Z. Report level fl 350.' a climb was initiated and the cpdlc message was acknowledged at XA23Z with wilco. We then received confirmation at XA25Z with 'level at FL350'. Obviously we had misinterpreted the chime as a cabin call; when in fact it was an ATC uplink chime directing an altitude change. Preventative measures could include emphasis in briefings that cpdlc equipped aircraft have the possibility of receiving revised oceanic clearances via ATC uplink as well as via SELCAL.

Title: An overwater B767ER flight crew failed to comply with a time restricted climb clearance when they mistook an ATC clearance uplink chime for a call from the Flight Attendants.

Narrative: Flight had obtained Oceanic Clearance normally from New York Oceanic; and had entered NAT track at JOBOC; FL 340 proceeding to 41N060W. At approximately XA02Z; the Flight Crew heard a chime and responded to a cabin call from Flight Attendants. About ten minutes after the conversation had ended on the interphone; the Captain noticed the upper EICAS screen had white 'ATC' displayed. ATC key on the FMS was selected and an ATC UPLINK was present: 'Climb to reach FL 350 by XA17Z. Report level FL 350.' A climb was initiated and the CPDLC message was acknowledged at XA23Z with WILCO. We then received confirmation at XA25Z with 'Level at FL350'. Obviously we had misinterpreted the CHIME as a cabin call; when in fact it was an ATC Uplink chime directing an altitude change. Preventative measures could include emphasis in briefings that CPDLC equipped aircraft have the possibility of receiving revised Oceanic Clearances via ATC Uplink as well as via SELCAL.
