the data token is invoked by an operator connected to the slave MCU, the
slave MCU checks if another participant possesses the data token. If yes,
the request is rejected. If no, the request is transferred to the Master
MCU, which opens the FECC/LSD channel of all the participants in the
Master conference.
Large Video Switching Conferences
Running video Switching conferences on the Standard Audio card limits the
maximum number of participants in a conference to 16 (12 video and 4 audio
only). This number of participants may be increased to up to 30 participants
when configuring the Audio Bridge component of the standard Audio card to
1/30. With the Audio+ card, up to 100 participants at 128 Kbps may connect
to one Video Switching conference (without special configuration).
Greet and Guide Conferences
A Greet and Guide conference is a conference with an AV Message Service
assigned to it, where participants are moved by the operator from one stage to
another during their connection to the conference.
An AV Message Service is a set of audio messages (two per Message Service)
and a video slide assigned to a conference. This set is activated when a
participant connects to an Attended conference to which the set is assigned.
There are two types of Greet and Guide - Attended conferences:
• Welcome (No Wait) conference
The participant is greeted by a video slide and the audio message when
connecting to the conference. After a pre-defined period, the participant
automatically connects to the conference without the operator’s
assistance.
• Attended (Wait) conference
The participant is greeted by the video slide and the audio message, and
then waits for the operator‘s assistance in the Participants Queue.
You can define a Greet and Guide conference via the WebCommander, but
conferences can be managed from the MGC Manager application. If you have
the Audio+ card installed on the MCU, define an IVR enabled conference
instead.
For more details regarding Greet and Guide conferences, see the MGC
Manager User’s Guide Volume II, Chapter 3.
