Conference On Port (COP)
In a Conference On Port, all participants use a single video port for the
conference. This enables the selection of a video layout for the conference but
all the participants, including the speaker, view the same layout and the same
participants. Personal layout selection is not available in COP and the video
quality is determined by the highest common video parameters and by the
video line rate.
In order to maintain an acceptable video quality during a Conference On Port,

support a video connection. This minimum threshold line rate is determined
by the Line Rate parameter defined for that conference.
