Configure The Multicast Parameters - CyberData 010935F Operation Manual

4.2.8 Configure the Multicast 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.
The Multicast Configuration page allows the Intercom to join up to 10 paging zones for receiving
ulaw/alaw encoded RTP audio streams. A paging zone can consist of one or many CyberData
multicast group-enabled products. There is no limit to how many speakers can be in a given paging
zone. Each multicast group is defined by a multicast address and port number. Each multicast group
is assigned a priority, allowing simultaneously arriving pages to be serviced based on importance.
Multicast groups are compatible with IGMP through version three. The Intercom supports
simultaneous SIP and Multicast.
