Chapter 4 - Setting Up Conferences

T120 Rate
• When the conference is set to a higher line rate,
the following T.120 rates are available:
H-MLP-64k; H-MLP - 128k.
Note:
• Set the same T.120 rate for all participants. This
should be the highest rate common to all
participants.
• When the conference line rate is 2B or 128 Kbps,
selecting a higher T.120 rate results in a loss of
video quality.
FECC/LSD Rate Enables the LSD mode on video cameras that
enables participants to control their far-end camera.
Note:
• In Video Switching conferences, if an endpoint
does not support LSD and cannot open the data
channel, the participant connects as Audio Only
(Secondary).
• In Continuous Presence and Transcoding
conferences, endpoints that do not support LSD
remain connected at their initial line rate.
For a detailed description, see the MGC Manager
User’s Guide Volume II, Chapter 1, “Far End
Camera Control (FECC) and Low Speed Data
(LSD)”.
Conference Lock Select this option to lock the conference to
undefined (“Meet Me”) dial-in participants and
prevent them from joining the conference once it has
started. Clear this check box to unlock a locked
conference.
A locked conference can be unlocked while it is in an
On Going state.
Note:
This option is enabled only for Meeting Rooms and
for standard conferences set as Meet-Me-Per-
Conference and Entry Queue Access, and only if the
Audio+ card is installed in the MCU.
