Integrations with Other Systems
Polycom, Inc. 176
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. If you don’t have a
RealPresence Resource Manager system (or for some reason don’t want to integrate to it), both kinds of
information can be manually configured on the RealPresence DMA system.
While the RealPresence DMA system is integrated with the RealPresence Resource Manager system, site
topology and user-to-device association may only be configured on the RealPresence Resource Manager
system. If the integration is terminated, the RealPresence DMA system retains the information last obtained
from the RealPresence Resource Manager system, but it becomes editable.
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 into account the conversion factor value so that the RealPresence DMA
system’s call bandwidth requirement calculations are predictable.
Note: Split Network configuration and resource management system integration
The RealPresence DMA system currently does not support integration with a Polycom RealPresence
Resource Manager system when configured for split network interfaces on the Admin > Local
Cluster > Network Settings page.
Note: Considerations for RealPresence Resource Manager integration
A RealPresence Resource Manager system can also be integrated to (connected to) the
RealPresence DMA system. This enables it to use the RealPresence DMA system’s RealPresence
Platform API to set up and monitor scheduled and preset dial-out (anytime) conferences using the
RealPresence DMA system’s resources (see RealPresence
®
Platform API).
When you integrate a RealPresence Resource Manager system to the RealPresence DMA system
(from its management interface), the RealPresence DMA system automatically integrates itself back
to the RealPresence Resource Manager system, making it unnecessary to perform the integration
described here.
When you integrate the Polycom RealPresence Resource Manager system to a RealPresence DMA
supercluster with embedded DNS enabled (see Embedded DNS), in its Add DMA dialog, select
Support DMA Supercluster.
Note: Add required DNS servers to the system
DNS servers must be able to resolve the RealPresence DMA system’s FQDN to its IP address. See
Add Required DNS Records for the Polycom RealPresence DMA System.
In addition, the DNS servers must be able to resolve the Polycom RealPresence Resource Manager
system’s FQDN to its IP address. This is necessary even if you specify the Polycom RealPresence
Resource Manager system’s IP address when you join it.
