Called from the floor by players anytime a player on their team is in control of the ball, or whenever the ball is dead (once you are scored upon, you are deemed to be in control, so no time-outs after you score a basket as is possible in the NCAA)
The Head Coach may also request a time-out from an official.
A player may not call timeout if both of his/her feet are in the air and any part of his/her body has broken the vertical plane of the sideline, baseline, or midcourt line
Ball may be advanced to front court (the 28' line [8.53 m], in specific) in some situations after calling a full or 20 second time out late in the game
