Flight attendants aboard a B747-400 notified the flight crew of inoperative cabin PA and interphone handsets at several doors during taxi for takeoff. Only after takeoff and the initial food service were the flight attendants advised that the inoperative handsets were deferable and that notification occurred only because flight attendants took the initiative to call and ask.

Narrative:
[I] was told that there were cabin lighting problems during our briefing. But when we got on the plane the mechanic was not just trying to fix the lighting but also the PA system and interphones. The PA and interphone were still not working at my jumpseat after the door was closed. I informed the purser immediately but we still took off without the PA system and interphones on doors 2L/right; 3L/right and 4L/right. We lost almost 50% of PA system and interphones for 15 hour flight and nobody mentioned any other communication method regarding emergency procedures.
