The EMU timer can be administered on the Features-Related System Parameters screen. The EMU timer applies to the visited server only. You can administer the timer for each server in the system. The amount of time a visitor can remain registered during a period of inactivity is entered in the EMU Inactivity Interval for Deactivation (hours) field. Valid entries are one to 24 hours. If the entry is left blank, the EMU timer is not used and the visited station remains registered until it becomes unregistered by other means.
