Chapter 4-Additional Conferencing Information

Polycom, Inc.

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.
—

Cascade Resolutions of HD720/5 and HD1080/15 are selectable with 256 kbps and 

768 kbps allocated as the Conference Content Rate respectively.

The higher Cascade 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 Cascade 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.
