Polycom 2000/4000 manual Resource Capacity Modes, 17-41

Polycom RMX 2000 Administrator’s Guide

•RMX’s with 500MB of memory can support a maximum of 400 simultaneous participant calls, regardless of how system resources are allocated. This limitation applies to RMX’s configured with either MPM or MPM+ cards. RMX’s with 1000MB of memory are not subject to this limitation.

•RMX memory size is listed in the Administration > System Information properties box. For more information see "System Information” on page 16-61.

Resource Capacity Modes

The installed media card type (MPM and MPM+) determines the Card Configuration Mode, which in turn determines the resource allocation method that can be selected for the RMX. It determines how the system resources are allocated to the connecting endpoints.

The System Card Configuration Mode determines the resource allocation method used by the RMX to allocate resources to the connecting endpoints. The method in which the system allocates the resources is defined in the Video/Voice Port Configuration. Two allocation methods are available:

•Flexible Resource Capacity™ – This is the same as the allocation mode used in all previous versions. The system allocates the resources according to the connecting endpoints. This mode offers flexibility in resource allocation and is available in both MPM and MPM+ Card Configuration Modes.

In Flexible Resource Capacity mode, in both MPM and MPM+ Card Configuration Modes, the maximum number of resources is based on the system license, regardless of the hardware configuration of the RMX. These resources are allocated as CIF resources by default.

Example: If the RMX is licensed for 80 video resources, but only one MPM card is currently installed in the RMX, the system lets you allocate 80 ports although only 40 video resources are available for participant connection. (However, an active alarm will be added to the Active Alarms list indicating a resource deficiency).

•Fixed Resource Capacity™ – This mode offers precise usage of resources, allowing the administrator to set the number of resources guaranteed to each Audio Only and video connection type in advance. This mode is available only in MPM+ Card Configuration Mode.
