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. 

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.

Fixed Resource Capacity enables the administrator to allocate the number of 

resources available to each video connection type and Audio Only 

connections in advance. In Fixed Resource Capacity mode, the system is 

always in a known state, and when used in conjunction with the Resource 

Report, it gives the administrator precise control over resource allocation 

and optimization. For more information, see "Forcing Video Resource 

.

Fixed Resource Capacity mode is available only in MPM+ System Card 

Configuration Modes.
If all resources allocated to a specific endpoint type are in use and an 

endpoint of that specific type tries to connect to the RMX, the RMX first 

attempts to connect the endpoint at the next highest resolution. If not 

resources are available at that level the RMX begins search for connection 

resolutions at progressively decreasing resolutions.
Example: In a system that has 10 SD ports allocated and in use:

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.
