Operator Conference

In Continuous Presence mode, a special conference that enables the RMX user, acting as an operator, to assist participants without disturbing ongoing conferences and without being heard by other conference participants. The operator can move a participant from an Entry Queue or ongoing conference to a private, one-on-one conversation in the Operator conference.

Video Resolutions

Resolution Configuration for CP

The Resolution Configuration dialog box enables the RMX administrator to modify the video resolution decision matrix, effectively creating his/her own decision matrix. The minimum threshold line rates at which endpoints are connected at the various video resolutions can be optimized by adjusting the resolution sliders.

For more information see the RMX 1500/2000/4000 Administrator’s Guide "Resolution Configuration” on page 2-12.

Video Switching

In Video Switching (VSW) mode all participants see the same video picture (full screen). Only one CIF video resource is used for each connection.

VSW mode conferencing is defined by:

—Resolution – HD720 or HD1080.

•Endpoint capabilities:

—Participants connecting to VSW conferences must have HD or SD capable endpoints. If not, they are connected as Secondary (Audio Only participants).

•HD_THRESHOLD_BITRATE system flag – determines the minimum line rate at which at which an HD channel will be opened.
