guaranteed to each Audio Only and video connection according to the
video resolution in advance. This mode is available only in MPM+
and MPMx Card Configuration Modes and is not relevant to MCUs
used for Audio Only conferencing with no video connections.
Resource Usage - Voice Resources
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.
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.
Flexible Resource Capacity mode is available and is the default selection in
both MPM, MPM+ or MPMx System Card Configuration Modes. It is the
only allocation method in MPM System Card Configuration Mode.
Fixed Resource Capacity
Fixed Resource Capacity enables the administrator to allocate the number of
resources available to each video connection type and Audio Only
connections in advance. Fixed Resource Capacity mode is available only in
MPM+ and MPMx System Card Configuration Modes and should not be
selected when the RMX is used only for Audio Only conferencing.
If there are no available CIF resources the system tries to allocate
resources to the SD endpoint from any available Audio Only resources. If
Audio Only resources are allocated the HD endpoint, it is connected as an
Audio Only participant.
