Paging system
First Claim
1. A decentralized public address paging system including:
- a combined data and digital audio network;
a plurality of public address paging system consoles, each including an operator interface to select one or more paging destinations and arranged to transmit data packets including paging destination data across said network; and
a number of public address addressable amplifier modules in communication with said network and responsive to the data packets, each of said amplifier modules having an associated address and is arranged to operate according to whether paging destination data contained within the data packets relates to said associated addresscharacterized in thateach paging system console is configured to listen to page control data packets received from other paging devices on the network to generate an engaged paging destination set and resolve the simultaneous transmission of data packets to the same paging destination using priority whereby paging system consoles transmitting lower priority data packets locally store the packets for later forwarding; and
wherein the engaged paging destination set is a set of destination zones for currently active paging events.

Abstract
The present invention relates to a distributed paging system. The distributed paging system includes a combined data and digital audio network and a plurality of paging system consoles. Each paging system console includes an operator interface to select one or more paging destinations and is arranged to transmit data packets including paging destination data across the network. A number of addressable amplifier modules are provided in communication with the network and are responsive to the data packets. Each of the amplifier modules has an associated address and is arranged to operate according to whether paging destination data contained within the data packets relates to the associated address.

27. A decentralized public address paging system including;
-
a plurality of public address paging console units, each including an operator interface to select one or more destination paging zones, a microphone and a network interface circuit for transmitting digital audio signals and command signals across a network; and a number of public address addressable amplifiers each including a network interface circuit in communication with the network and arranged to transmit data indicating operational status and local ambient acoustic conditions across the network characterized in that each paging system console is configured to listen to page control data packets received from other paging devices on the network to generate an engaged paging destination set and resolve the simultaneous transmission of data packets to the same paging destination using priority whereby paging system consoles transmitting lower priority data packets locally store the packets for later forwarding; and wherein the engaged paging destination set is a set of destination zones for currently active paging events.
