High Definition Video Switching
During a High Definition Video Switching conference, each endpoint uses
one video (CIF) port.
Voice
One Audio Only resource is used to connect a single voice participants
once CIF resources have been converted to Audio Only. However, if no
CIF resources were converted, Audio Only endpoints use one CIF video
resource per connection.
When video ports are fully used, the system cannot use free audio ports
for video. When audio port resources are fully used, video ports can be
used, using one video port to connect one voice participant.
Video/Voice Port Configuration
The Video/Voice Port Configuration enables you to configure the RMX
Resource Capacity and if in MPM+ System Card Configuration Mode, to
select the capacity method.
Flexible Resource Capacity Mode
All resources are initially allocated as CIF video ports as it is a resolution
commonly supported by all endpoints.
The administrator can allocate some or all of these resources as Voice
resources and let the system allocate the remaining Video resources
automatically as participants connect to conferences. The system
automatically allocates resources according to the connecting
participant’s endpoint type, capabilities and line rate.
Flexible Resource Capacity mode is available and is the default selection in
both MPM and MPM+ System Card Configuration Modes. It is the only
allocation method in MPM System Card Configuration Mode.
If the system runs out of voice ports, voice endpoints cannot connect to available
video ports. Conversely, video endpoints cannot connect to available voice
ports.
