Note: Resource Usage Reporting

The RealPresence DMA system reports port numbers based on resource usage for CIF calls. Version

8.1and later Polycom MCUs report port numbers based on resource usage for HD720p30 calls. In general, 3 CIF = 1 HD720p30, but it varies depending on bridge/card type and other factors.

See your Polycom RealPresence Collaboration Server or RMX system documentation for more detailed information about resource usage.

Considerations when using MCUs with the RealPresence DMA system

In high security mode, the RealPresence DMA system uses only HTTPS for the conference control connection to MCUs, and you must configure your MCUs to accept encrypted connections. We recommend doing so. When unencrypted connections are used, the MCU login name and password are sent unencrypted over the network.

The Polycom RealPresence DMA system knows only what resources an MCU has currently available. It can’t know what’s been scheduled for future use.

If you have a Polycom CMA system and want to use the same RMX MCU (v6.0 and above) for both reservationless and scheduled conferences, determine how many ports you want to set aside for scheduled conferences and designate those as ports reserved for the CMA system. This feature is not available for Cisco Codian MCUs or for use with a Polycom RealPresence Resource Manager system. The RealPresence Resource Manager system must have exclusive use of any MCUs on which it directly schedules conferences. Those MCUs should not be added to the RealPresence DMA system’s conferencing resources.

The Automatic Password Generation feature, introduced in RMX version 7.0.2, is not compatible with the Polycom RealPresence DMA system. On Polycom MCUs to be used with the Polycom RealPresence DMA system, disable this feature by setting the system flags NUMERIC_CONF_PASS_DEFAULT_LEN and NUMERIC_CHAIR_PASS_DEFAULT_LEN both to 0 (zero).

The following table describes the fields in the list (the View Details command lets you see this information in a more readable form for the selected MCU).
