The Video Gateway is one element used in LAN conferencing.
Conference calls can be voice, video, or data format or a combination of formats.
Each format has unique transmission requirements. These requirements take up a portion of the network's total transmission capacity, and can affect the speed with which information travels from one point on the network to the next. Conference management stations give network administrators flexibility in managing the flow of traffic on the network. The stations allow the administrator to design call services based on the call-format's transmission requirements. Call services make efficient use of the network's transmission bandwidth.
