Narrative:
Enroute at 34;000 feet the number one pressure controller faulted. We followed ECAM procedures and selected the number two pressure controller. It also failed shortly after the first. We again followed ECAM procedures; used the manual pressure controller; and descended on oxygen masks to 10;000 feet under center control and received vectors to destination. We followed all ecams; appropriate checklists and performed an uneventful ILS.
