Star Configuration: Five Systems

In this example, system users make calls in the same way as they would in a
series configuration. The primary difference between a star configuration and a
series configuration is that in a star configuration all network-routed calls pass
through a central hub system , in this case, a DEFINITY ECS or DEFINITY
ProLogix Solutions system. The hub normally terminates stations as well as
external facilities.
