Chapter 2-Conference Profiles
Polycom, Inc. 2-11
— SVC endpoints support both AVC and SVC video protocols.
When dialing into SVC Only conferences, they connect as SVC endpoints.
When dialing into AVC Only conferences, they connect as AVC endpoints. They
cannot connect to an AVC conference using the SVC capabilities.
• SVC endpoints can connect to conferences via Entry Queues, however:
— The Entry Queue and Conference Modes must match - both SVC Only or both
Mixed.
— Both the Entry Queue and the Conference must have the same line rate.
• SVC endpoints cannot be moved between conferences.
• Content is supported in H.264 (AVC).
— Only the H.264 Cascade and SVC Optimized option is supported.
— LPR and DBA are not supported for SVC content sharing.
• In SVC Only conferences and Mixed CP and SVC conferences, Auto Layout is the
default and the layout display for SVC endpoints is controlled from the endpoint
application.
• Site names display on SVC endpoints is controlled from the SVC endpoints.
• When DMA is part of the solution, the DMA is used as the SIP proxy and the SVC
endpoint subscribes to DMA for call control. If a DMA is not part of the solution, the
SVC endpoint dial directly to the Collaboration Server using IP addresses is the SIP
dialing strings.
• When Hot backup is enabled, all the conferences are created on the Slave MCU.
• When Hot Backup is activated and the Slave MCU becomes the Master MCU:
— All AVC endpoints will be reconnected to the AVC conferences. SVC endpoints
connected to AVC conferences using their AVC capabilities will be reconnected to
their AVC conferences.
— SVC endpoints cannot be reconnected to their SVC Only conferences as dial-out is
not supported for SVC endpoints. These endpoints will have to manually
reconnect to their SVC conferences.
• Cascading between SVC Only conferences or between AVC and SVC Only conferences
is not supported.
• The following functionality and features are not supported during SVC Only
conferences:
— FECC
— Skins. The video cells are displayed on the endpoint’s default background.
— Conference Gathering phase
— Password protected conferences as DTMF input for passwords cannot be
processed
— Manual selection of video layout
— Recording of SVC Only conferences
— Text messaging using Message Overlay
