The good ol C-5 has a similar system. It has changed quite a bit over the years, I imagine the 777 system is MUCH improved over what the C-5 has. The C-5 has MADARS (malfunction analysis detection and recording system). Pretty much hated by all that touch the system!
The A330/340 has the Central Maintanence System and the 320s have the Centralized Fault Display System. It works pretty much the same way, integrating fault and test access, but its accessed through the pilots' MCDUs.
