Optimizing Your System 5

This section describes some features and applications that you read about in the scenarios. They are highlighted here because they can significantly enhance your system.

For more information about any of these products and features, see the Feature Reference or contact your Lucent Technologies representative for additional guides or applications notes.

NOTE:

The Data/Video Reference includes additional information about videoconferencing, Internet access, and other data communications support.

Desktop Videoconferencing 5

A desktop videoconferencing application is designed for individual video calls, data transfer, and screen-sharing between two compatible personal computers that are running compatible software.

Some desktop videoconferencing systems can use either one MLX B-channel or two, although one is often not of adequate quality (other desktop video systems support only 2B data). The use of one B-channel is called 1B data; the use of two data channels is referred to as 2B data. Depending upon the type of high-speed digital facilities and interface arrangement connected to your system, 1B data transfer takes place at 56 or 64 kbps, and 2B data transfer takes place at 112 or 128 kbps. The 2B Data feature allows the use of a single MLX port for desktop videoconferencing; both the main and adjunct extension numbers are used.

An MLX telephone may be connected to some desktop videoconferencing systems. The telephone shares the MLX extension. If the MLX telephone is on a call, the desktop videoconferencing application has only one B-channel available and is limited to 1B data. On some systems, the second B-channel is added when the MLX telephone becomes idle. See the Data/Video Reference for more information about desktop videoconferencing.
