Chapter 3-Additional Conferencing Information<br />

Endpoints that do not support the required content parameters (Content line rate, H.264<br />

protocol and Content Resolution), along with ISDN endpoints, can be connected as Legacy<br />

Endpoints and receive content through their video channel. This ensures that Content settings<br />

are not changed following the participants connection or disconnection from the conference.<br />

If the Send Content to Legacy Endpoints option is disabled, these endpoints will not receive<br />

content.<br />

<strong>Guide</strong>lines<br />

• The cascade link must be H.323.<br />

• H.323, SIP and ISDN participants are supported.<br />

• H.264 High Profile is not supported.<br />

• In MPM+ Card Configuration Mode, maximum supported content resolution is HD 720p.<br />

• When H.264 Cascade Optimized is selected, the Send Content to Legacy Endpoints selection<br />

is enabled by default in the Conference Profile – Video Settings dialog box.<br />

• Endpoints that cannot connect at a line rate required to support the conference Content<br />

Rate are considered Legacy Endpoints and will receive Content in the video channel.<br />

Enabling H.264 Cascade Optimized Content Sharing<br />

When H.264 Cascade Optimized is selected as the Content Protocol, an additional field, Cascade<br />

Resolution is displayed in the Content Video Definition pane.<br />

The Cascade Resolution is a fixed resolution and frame rate for Content sharing in a Cascaded<br />

Conference. The Cascade Resolutions that are available for selection are dependent on the Line<br />

Rate and Content Settings that have been selected for the conference.<br />
