Polycom RMX 2000 Administrator’s Guide

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.

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.

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

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 Allocation to CIF Resolution” on page 16-50.

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:
