Narrative:
The flight was cleared to 11000 ft. The controller asked if the flight was expediting to 10000 ft. The captain told the controller the flight was level 11000 ft. The controller then gave the flight a TA call and told us to immediately descend to 10000 ft. It was at that time a TCASII RA had occurred.
