Narrative:

On taxi out the aircraft lost nosewheel steering control via tiller and momentarily had no brakes. ECAM advised nosewheel steering fault and alt brakes kicked in. Aircraft control was degraded and captain chose to turn left onto the nearest ramp to clear traffic and stop for maintenance action. Maintenance came to the aircraft to troubleshoot problem via interphone and inspection of the nose landing gear. Control established after cycling antiskid switch. We returned to gate for check of brake steering control unit. Following good test and refuel; flight taxied out again.
