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).
