Site-link replication schedules

As opposed to intra-site replication, inter-site replication, by default, uses a replication schedule. Instead of processing change notifications, domain controllers wait their scheduled replication time, based on an interval.

By default, domain controllers on each side of the site link replicate every 180 minutes and the site link's replication schedule is to allow replication Sunday through Saturday from 12:00 A.M. to 12:00 A.M.
