Abstract
According to a system for switched cutover with paced transition, subscribers are transitioned to a new communication system while the capacity needed by the cutover facility is minimized. A cutover facility between a pre-cut switch and a post-cut switch for transitioning a first and a second set of subscribers from a first communication system to a second communication system is established. The migration of the first and the second set of subscribers from the pre-cut switch to the post-cut switch is begun. A transition midpoint is identified. The transition midpoint occurs when the number of subscribers migrated to the post-cut switch is equal to the number of subscribers remaining on the pre-cut switch. End office traffic routed to the pre-cut switch is then shifted to the post-cut switch in response to the transition midpoint being identified. Finally, the remaining subscribers are shifted to the post-cut switch. This transition may be performed using a slice-cut dial-with-dial transfer.
