The Site Selectable Alert List Page (Voice Announcements)

	Up to fifteen different Site Selectable Alerts per List may be defined for encoding and / or decoding by the radio; however, only an SSA that has its Subscriber Encodable field "enabled" can be radio-user selected for encoding (sending to the FNE). Once the FNE receives an SSA from a radio, it then broadcasts it to all radios at a site using a proprietary Motorola System Broadcast OSP (Outbound Signaling Packet) on the outbound Control Channel.
	Audio from a standard Voice Announcement (a one-time event) is always given priority over Site Selectable Alert audio (a recurring event).
	Only one Site Selectable Alert can be active at a site at any given time.

	The appropriate Motorola Voice Announcement Files (*.MVA) must first be loaded into the Voice Announcement List before they may be selected for a Site Selectable Alert List record / row from the corresponding Alert Audio File field.
	A Site Selectable Alert List can be then assigned to a Trunking System through its Site Selectable Alert List Selection field.
	Site Selectable Alerts which have their Subscriber Encodable field "enabled" are radio-user activated and deactivated with a Site Selectable Alert menu-selection. Either a single site or all available sites in the Zone can be selected for activating or deactivating a Site Selectable Alert.
