2.3.8 Configure the Multicast Configuration Parameters

Multicast groups use multicasting to create public address paging zones. Multicasting is based on

the concept of a group. Multicast addresses specify an arbitrary group of IP hosts that have joined

the group and want to receive traffic sent to the group. Group members send IGMP messages to

their local multicast routers, allowing the group traffic traversal from the source.

Multicast configuration provides the ability to join up to 10 paging zones. A paging zone can consist

of one, or many, CyberData multicast group-enabled Loudspeaker Amplifiers. There is no limit to

how many Loudspeaker Amplifiers can be in a given paging zone. Each multicast group is defined

by a multicast address and port number. Each multicast group is also assigned a priority, allowing

simultaneously arriving pages to be serviced based on importance. Multicast groups are compatible

with IGMP through version 3.

Note The Loudspeaker Amplifier supports simultaneous SIP and Multicast.
