Chapter 19-Collaboration Server Administration and Utilities
Polycom, Inc. 19-7
You can set the MCU to allocate one CIF video resource to an endpoint, regardless of the
resolution determined by the Conference Profile parameters. This forcing saves resources
and enables more endpoints to connect to conferences.
The forcing is done by modifying the system configuration and it applies to all conferences
running on the MCU.
You can specify the endpoint types for which resource allocation can be forced to CIF
resource, enabling other types of endpoints to use higher resolutions in the same conference.
For example, you can force the system to allocate one CIF video resource to CMAD and VSX
endpoints while HDX endpoints can connect using SD or HD video resources.
Once the endpoint connects to the conference, its type is identified by the Collaboration
Server and, if applicable, the Collaboration Server will connect it using one CIF resource,
even if a higher resolution can be used.
To force CIF resource:
1On the Collaboration Server menu, click Setup > System Configuration.
The System Flags dialog box opens.
2In the MCMS_PARAMETERS tab, click the New Flag button.
The New Flag dialog box is displayed.
3In the New Flag field enter the flag name: FORCE_CIF_PORT_ALLOCATION
4In the Value field enter the product type to which the CIF resource should be allocated.
Possible values are:
—CMA Desktop for CMA desktop client
—VSX nnnn where nnnn represents the model number for example, VSX 8000.
You can define several endpoint types, listing them one after the other separated by
semicolon (;).
For example, CMA Desktop;VSX 8000.
5Click OK.
The new flag is added to the flags list.
Reset the MCU for changes to take effect. For more details, see the Polycom RealPresence
Collaboration Server (RMX) 1800 Administrator’s Guide, "Resetting the Collaboration Server
(RMX)” on page 19-54.
To cancel the forcing of CIF resource:
1On the Collaboration Server menu, click Setup > System Configuration.
The System Flags dialog box opens.
2In the MCMS_PARAMETERS tab, double-click or select the flag
FORCE_CIF_PORT_ALLOCATION and click the Edit Flag button.
3In the New Value field, clear the value entries.
4Click OK.
