Video Session Mode, Line Rate and Video Settings<br />

The types of MCUs, their position in the cascade topology and the<br />

endpoint capabilities (HD/CIF and H.263/H.264) determine the Video<br />

Session Mode of the MIH Cascading conference.<br />

• When creating a cascading link between two <strong>RMX</strong>s:<br />

— The <strong>RMX</strong>s operate in CP (Continuous Presence) mode.<br />

• When creating a cascading link between MGCs and <strong>RMX</strong>s:<br />

— If there are no MGCs on level 2, the MGCs can operate in either<br />

in CP or VSW (Video Switching) mode.<br />

— If there are MGCs on level 2, the MGCs can only operate in VSW<br />

mode.<br />

• When creating a cascading link between two MGCs:<br />

— The MGCs must be configured to operate in VSW mode.<br />

For more details about the MGC to MGC connection, see the MGC<br />

Manager User’s <strong>Guide</strong>, Volume II, Chapter 1, “Ad Hoc Auto Cascading and<br />

Cascading Links”.<br />

To enable the connection of the links between cascaded conferences, they<br />

must run at the same line rate.<br />
