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.
Group Videoconferencing 5
Group videoconferencing enables groups of people in different geographical
locations to meet face to face. The applications differ from desktop systems
primarily in the size of their screens and the sophistication of the features they
provide. Conferees can exchange information, documents, ideas, and data while
