2.4 Set up the MGROUPS

MGROUPS uses 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.

MGROUPS Setup provides the ability to join up to 10 Paging Zones. A Paging Zone can consist of one, or many, CyberData MGROUPS-enabled speakers. There is no limit to how many speakers can be in a given Paging Zone. Each MGROUP is defined by a multicast address and port number. Each MGROUP is also assigned a priority, allowing simultaneously arriving pages to be serviced based on importance. MGROUPS are compatible with IGMP through version 3.
