To answer the original questions. The RSV rules at 9E are as follows: For the time Crew Sched originally calls you during you reserve period you have 15 min. to call them back. For example if they call you at 1100 you have to call them back by 1115. Once you have called them back and been notified you have exactly 1.5 hours to get to your departure gate. So if you called them back at 1110 you would need to be at the departure gate by 1240. Bottom line get a crash pad and plan on being there during your reserve days.
