The selection of the appropriate Content Resolution option, when several options are available, should be
based on the line rate and capabilities that can be used by most or all endpoints connecting to the
conference.
Examples:
● If the conference Line Rate is 1024 kbps.
and
● If the Content Settings selection is Graphics.
 Content Resolutions of HD720/5 and HD1080/15 are selectable with 256 kbps and 768 kbps
allocated as the Conference Content Rate respectively.
The higher Content Resolution, HD1080/15 should be selected only if most of the endpoints
connecting to the conference can support a Content Rate of 768Kbps, which requires the
participant to connect to the conference at a Line Rate of 1024kbps.
When the lower Content Resolution HD720/5 is selected, the conference Content Rate is set to
256 kbps. This will enable the endpoints that connect to the conference at a Line Rate of at least
768 kbps to receive content in the Content channel. Endpoints that connect to the conference at
a line rate lower than 768Kbps, will receive content in the video channel.
● If the Content Settings selection is Hi Resolution Graphics.
 Only HD720/5 can be selected as the Content Resolution with 384 kbps allocated as the
conference Content Rate.
