• Multiple Resolutions (Content Transcoding) is not selected.
• The selected Content Protocol is H.264 HD, H.264 Cascade and SVC Optimized

automatically set according to the line rate and the H.264 High Profile check box
is automatically unchecked and disabled.

Server with MPMRx or Realpresence Collaboration Server 1800) and can be up to
66% of the conference line rate. In MCUs with MPMRx cards the Content Rate is
limited to 2048 kbps, while when used with the Realpresence Collaboration Server

When enabled, an additional HD video resource is allocated to the conference.
• This option is valid when sending Content as a separate stream is enabled by the
System Flag ENABLE_H239 set to YES.
• Select this option when Avaya IP Softphone will be connecting to the conference.
• If the Same Layout option is selected, the Send Content to Legacy Endpoints
selection is cleared and is disabled.
• Once an endpoint is categorized as Legacy, it will not be able to restore its
content to the Content channel and will receive content only in the video channel.
