Chapter 7 - Defining a New Video Conference

connect participants to the conference at this line rate or lower, according to their individual capabilities.

In a Conference On Port (COP), select the estimated highest transfer rate common to all participants. In this mode, all conference participants must use the same video parameters.

In order to maintain a minimum video quality for a Conference On Port, there is a minimum threshold line rate that participants must support in order to connect with video. The minimum line rates necessary to connect to a Conference On Port are displayed in Figure 7-1. Participants attempting to connect at rates below the minimum conference line rate threshold are connected as Secondary (Audio Only).

16.In the Msg Service Type field, select IVR or None for a conference without voice messages. An IVR service allows participants to interact with the MCU by using DTMF codes and provides functionalities such as Conference Entry password, Conference Chairperson identification, Roll Call, Invite and Click&View. For more information about IVR, see the MGC Manager User's Guide, Volume II, Chapter 2.
