MIH 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 Type of the MIH Cascading conference.
● When creating a cascading link between two RMXs:
 The RMXs operate in CP (Continuous Presence) mode.
 DTMF codes should be defined with the same numeric codes in the IVR services assigned to the
cascading conferences.
● 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.
 MGC does not support H.264 High Profile, therefore when MGC is part of the Cascading topology,
do not select High Profile on the RMX system.
 DTMF codes should be defined with the same numeric codes in the IVR services assigned to the
cascading conferences.
