ADSL needs to be filtered and so does ALL other equipment on the line. This includes any alarm equipment (red care for example). Red care does work with ADSL but most alarm companies recommend a dedicated line.
Line judges stand on the corner of the court and watch the ball. If the ball lands close to the end line or the side line that the line judge is supposed to be watching, the ref looks to the line judge to call the ball inside or outside of the court. If the ball is in, the line judge puts their hands down, and if it is out, they put their arms up in the air. The line judge also looks to see if the team touches the ball on the block, or in the backrow, before the ball goes out. For example, if there was a ball that was hit and the blockers on the side of the line judge touch the ball before it lands out of bounds, the line judge puts one hand up and the other hand on top of it, kind of like a time out in basketball.
