I think you are confusing between OEB for Bleed AIR ENG1(2) BLEED FAULT, AIR ENG 1+2 FAULT and ECAM EXCESS CAB ALT. If you get ECAM CAB PRESS EXCESS CAB ALTITUDE it means you cabin altitude is higher than 9550 and it will ask you to EMER descent. No trouble shooting you just do that.
If you only get AIR ENG 1(2) BLEED FAULT then apply the OEB first. The logic of the OEB is to get single bleed two packs operation to cater for pack fault of the existing bleed, by switching off the faulty bleed, opening the cross bleed and monitoring the pre cooler outlet temperature. If the temperature crosses 240C then use only single pack. There is no OEB for BLEED 1+2 fault.
If you get only ECAM AIR ENG 1+2 BLEED FAULT(No EMER DES) then apply ECAM procedure which is also given in QRH. It is basically reset procedure to recover one or both packs. If it doesn't then you need to do emergency descent to FL100 and during descent start APU and if you get APU bleed you can fly at 200.
