RealPresence Resource Manager Integration

Integrating with a Polycom ® RealPresence ®  Resource Manager system provides the Polycom ®  RealPresence ® DMA ®  system with the following information:

All site topology information configured in the RealPresence Resource Manager system.

The RealPresence DMA system uses site topology information for a variety of purposes, including cascade for bandwidth conferences, bandwidth management, and Session Border Controller selection.

All user-to-device associations configured in the RealPresence Resource Manager system in which the enterprise user is also known to the RealPresence DMA system.

The RealPresence DMA system uses user-to-device associations to assign classes of service to endpoints based on the user they belong to.

 

Note: The RealPresence DMA system currently does not support integration with a RealPresence Resource Manager system when the RealPresence DMA system is configured for split network interfaces.

Integrating with a RealPresence Resource Manager system allows you to configure site topology and user-to-device associations in one place instead of two, ensuring consistency. While integrated, you can only configure this information in the RealPresence Resource Manager system. If you do not have a RealPresence Resource Manager system, or if the RealPresence DMA system and RealPresence Resource Manager system are not integrated, both site topology and user-to-device associations can be manually configured in the RealPresence DMA system. If the integration is terminated, the RealPresence DMA system retains the information last received from the RealPresence Resource Manager system. You can then edit this information in the RealPresence DMA system.

When the RealPresence DMA system gets its site topology information from a RealPresence Resource Manager system, the first three territories assigned to a RealPresence DMA cluster are enabled for conference rooms.

The Bit rate to bandwidth conversion factor setting on the Call Server Settings page of the RealPresence DMA system can affect choices for bandwidth restrictions in your site topology. Since the RealPresence Resource Manager system calculates call bandwidth requirements using a conversion factor of 2.5, Polycom recommends using a Bit rate to bandwidth conversion factor value of 2.5 if you integrate with a RealPresence Resource Manager system. Otherwise, you will need to alter the bandwidth restrictions for your site topology to take the conversion factor value into account. This ensures that the RealPresence DMA system’s call bandwidth requirement calculations are predictable.
