Vne.  Speed a pilot is never to exceed in an aircraft.  Every craft has a different set of V speeds.
V Speeds
I know jack shit about flying anything other then single engine prop planes.  But I'd hazard a guess there no way that Airbus could get anywhere near Mach 1.  Well, maybe vertically headed down.

 Edit:  Looks like max airspeed for the Airbus is 615.  Mach 1 is 750, I think I'm not looking it up.  That's a little closer then I thought.  With a throttles full open and a tail wind maybe it could get damn close to the speed of sound.
