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:
• Conference Profile settings:
— Line Rate – From 192kbps to 6Mb (8Mb with MPMx). All
participants must connect at the same line rate.
— 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.
