Voice Office Application Suite Configuration GuideChapter 3 Broadcast Server InstallationHardware and Software Overview41Broadcast Server Operation with ClustersNote In this topic, the term Primary Application Gateway is used to refer to thelast Application Gateway in the cluster that registered with BroadcastServer. All other Application Gateways in the cluster are referred to asSecondary Application Gateways. This use of the terms Primary andSecondary does not imply that clusters support failover for this release.The Primary Application Gateway (the last server in the cluster thatregisters with Broadcast Server) is the one that receives alerts fromBroadcast Server. That Application Gateway then pushes the alert to therest of the cluster, the Secondary Application Gateways.Application Gateway failure impacts Broadcast Server as follows:• When a Secondary Application Gateway in a cluster fails, the phonesregistered to that Application Gateway will not have access to anyVoice Office applications and will not be able to receive pages orbroadcasts.• When a Primary Application Gateway fails, communication fromBroadcast Server to the cluster is halted until one of the SecondaryApplication Gateways re-registers with Broadcast Server. Tore-register an Application Gateway with Broadcast Server, restart theApplication Gateway.For information on setting up a cluster, refer to the Application GatewayAdministration Guide.Hardware and Software OverviewBroadcast Server is a software-only solution requiring installation of theserver software on a computer running Microsoft Internet InformationServices.Once installed on the IIS server, users may access Broadcast Server tocreate and manage content to be distributed, via the Application Gateway,to IP telephones.Broadcasts are received in the order in which they are sent. If a phone isbusy, a broadcast is queued.
