● In Cascading conferences, the cascade link must be H.323.
● This is the only available Content sharing mode in SVC and mixed CP and SVC Conferencing Modes.
● In SVC and mixed CP and SVC Conferencing Modes the Content Line rate is fixed at 128Kbps.
● H.323, SIP and ISDN (Collaboration Server 1500/2000/4000) participants are supported in AVC CP
Conferencing Mode.
● In Collaboration Server 1500/2000/4000, H.264 High Profile is not supported in MPMx Card
Configuration Mode. H.264 High Profile is supported in MPMRx card Configuration Mode and with
Collaboration Server 1800.

● When H.264 Cascade and SVC Optimized is selected in AVC CP Conferencing Mode, the Send
Content to Legacy Endpoints selection is enabled by default. Endpoints that cannot connect at a
line rate required to support the conference Content Rate are considered Legacy Endpoints and will
receive Content in the video channel.

conference Content Rate will receive Content in the video channel.
