By applying different service bulletins operators can upgrade their systems while in service.

Log into Airbus World to see the catalogue.

I have repeated myself a number of times, owners can customise the aircraft the way they want with equipment from different vendors. The catalog is available on Airbus World.
For example a Honeywell TPA-100 TCAS processor and EGPWS solution.
