Multicast Paging Volume (0 - 1 9, Factory Set - Viking 300TB-IP Product Manual

11. Standard or Polycom Multicast Paging
Standard
When using standard Multicast Paging, up to 10 multicast paging groups can be programmed into each 300TB-IP
speaker. 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. A timeout check box can be
selected for each paging group. See Multicast Page Timeout under Paging Settings to adjust the timeout from 1 - 255
seconds. Only one timeout time can be programmed for all groups. The volume for each multicast group can be
programmed separately.
Assigning Priority to standard Multicast Paging
The 300TB-IP will prioritize simultaneous audio streams according to their priority in the Paging Sources list. Group 0
will have the highest priority while group 9 will have the lowest priority. Group 9 is useful for a low priority stream such
as background music. Group 0 is useful for high priority streams such as emergency messages.
The multicast paging groups can also be used for up to ten different paging zones for receiving audio streams. A paging
zone can consist of one or many 300TB-IP multicast speakers. 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.
Polycom
Polycom IP phones send multicast audio to a specific IP address and port. A total of 25 groups can be used, with
group 25 generally reserved for an emergency broadcast. Set the Multicast Page Type to "Polycom". The Viking IP
programming page will then show "Polycom Paging Source and Group Subscriptions". Polycom phones will default
to IP address 224.0.1.116 and port 5001 for multicast. Under "Polycom Paging Source and Group Subscriptions",
enter the IP address and port you chose in the Polycom IP phone as "Multicast IP address" and "port" (Paging/PTT
Configuration page). Select the paging groups the 300TB-IP should subscribe to. Any multicast audio sent to the
correct IP address, port number and a subscribed group will be heard from the Speaker terminals. Group 1 is the
lowest priority and group 25 is the highest. The Volume and Timeout can be selected globally, although the timeout
does not affect group 25. Factory Setting: all Groups selected
12. Multicast Paging Volume
The volume of each individual standard multicast page can be adjusted from 0 - 19. When polycom paging is used,
the paging volume is set globally for all 25 groups. Factory Setting: 1
