Chapter 2-Additional Conferencing Information

Setting the Flags on the RMX 2000

When running conferences in mixed environment (RMX 2000 and MGC) there may be small differences between the line rates each MCU is sending. In the RMX 2000, several flags must be set to ensure that these differences will not cause the cascaded link to connect as Secondary and that Content flows correctly between the cascaded conferences. This procedure is performed once per RMX.

1In the RMX Web Client menu, click Setup>System Configuration.

2In the System Flags dialog box, add the following new flags and values:

MIX_LINK_ENVIRONMENT=YES

Setting this flag to YES will adjust the line rate of HD Video Switching conferences run on the RMX 2000 from 1920Kbps to 17897Kbps to match the actual rate of the HD Video Switching conference running on the MGC. In such case, the conference can include IP and ISDN participants.

IP_ ENVIRONMENT_LINK=NO

Setting this flag to YES will adjust the line rate of HD Video Switching conferences run on the RMX 2000 from 1920Kbps to 18432Kbps to match the actual rate of the IP Only HD Video Switching conference running on the MGC. In such case, the conference can include IP Only participants.

If the flag MIX_LINK_ENVIRONMENT is set to YES, the IP_LINK_ENVIRONMENT flag must be set to NO.

If the flag MIX_LINK_ENVIRONMENT is set to NO, the IP_LINK_ENVIRONMENT flag must be set to YES.

H263_ANNEX_T=YES (default)

This flag enables/disables the use of Annex T with H263. Set it to NO if the endpoints connecting to the conference do not support this mode. In such a case, you must also change the MGC flag ENABLE_H239_ANNEX_T setting to NO.

FORCE_1X1_LAYOUT_ON_CASCADED_LINK _CONNECTION=YES (default).

Set this flag to NO If the MGC is functioning as a Gateway and participant layouts on the other network are not to be forced to 1X1.
