Figure 2-6MIH Cascading – Master-Slave Relationship

Video Session Mode, Line Rate and Video Settings

The types of MCUs, their position in the cascade topology and the endpoint capabilities (HD/CIF and H.263/H.264) determine the Video Session Mode of the MIH Cascading conference.

When creating a cascading link between two RMXs:

The RMXs operate in CP (Continuous Presence) mode.

When creating a cascading link between MGCs and RMXs:

If there are no MGCs on level 2, the MGCs can operate in either in CP or VSW (Video Switching) mode.

If there are MGCs on level 2, the MGCs can only operate in VSW mode.

When creating a cascading link between two MGCs:

The MGCs must be configured to operate in VSW mode.

For more details about the MGC to MGC connection, see the MGC Manager User’s Guide, Volume II, Chapter 1, “Ad Hoc Auto Cascading and Cascading Links”.

To enable the connection of the links between cascaded conferences, they must run at the same line rate.
