Sending Content to Legacy Endpoints

The RMX can be configured to send Content to H.323/SIP/ISDN endpoints that do not
support H.239 Content (legacy endpoints) over the video (people) channel, allowing the
participants using legacy endpoints to view Content instead of the other conference
participants.

On the RMX menu, click Setup > System Configuration.
In the System Flags - MCMS_PARAMETERS tab, double-click the
MIN_H239_HD1080_RATE entry.
In the Update Flag - Value field, enter 0.
Click OK to exit the Update Flag and then again to exit the
System Flags dialog box.
This option is enabled in MPM+ and MPMx Card Configuration Modes only.
This option is valid when sending Content as a separate stream is enabled in the System
Configuration and the flag: ENABLE_H239 is set to YES.
Additional video resources are allocated to the conference when Content is sent to
legacy endpoints:
— In MPM+ mode, an additional SD video resource is allocated.
— In MPMx mode, an additional HD video resource is allocated.
The allocation is done only when a legacy endpoint is connected to the conference and a
Content session is initiated and transmitted via the video channel.
Once the resource is allocated, it remains allocated to the conference until the
conference ends.
If the system cannot allocate the resource required for sending the Content, the
conference status changes to "Content Resource Deficiency" and Content will not be
sent to the legacy endpoints.
As the resource required for sending Content to legacy endpoints is allocated on the fly,
when scheduling a reservation, in rare occasions when the MCU is fully loaded,
"Resource deficiency" may be encountered. This may prevent participants from
connecting to the conference or from Content being sent to the legacy endpoint. To
ensure resource for sending Content to legacy endpoints, add one resource to the
number of resources defined in the Reserve Resources for Video Participants field, in the
Conference Properties - General dialog box.
Non-H.239 (legacy) endpoints receive the Content via the video channel using the same
video protocol and resolution with which they receive video.
The highest Content resolution for legacy endpoints is:
— HD720p30 with MPMx
— HD720p5/6 with MPM+
Content cannot be sent to legacy endpoints when Same Layout mode is selected for the
conference.
This option in not supported in High Definition Video Switching conferences.
