I Applications
Videoconferencing
Making and receiving voice calls are not supported on telephones included with
videoconferencing systems.
Group Videoconferencing
Group videoconferencing enables groups of people in different geographical
locations to meet face to face. Conferees can exchange information, documents,
ideas, and data while employing a variety of visual aids. Visual aids can include
interactive writing and drawing, prepared text and graphic materials, and
prerecorded audio and video material. Improved technology, superior camera
optics, and digital audio signals result in video pictures that are equal to
commercial broadcast quality.
Users start videoconferences from an easy-to-use control console and conduct
the conference as easily as they operate a telephone. No special technical
expertise is required.
Group video systems are often integrated in a mobile roll-about console that can
be wheeled easily into a conference room or executive office prior to a scheduled
videoconference call. Alternatively, the components can be built into a
videoconference room.
Older group videoconferencing systems use V.35 interfaces, requiring two ISDN
terminal adapters or an inverse multiplexor (IMUX); these components are
sometimes included with the systems. Newer group videoconferencing systems
use ISDN/BRI interfaces and include data communications equipment.
Desktop Videoconferencing
Desktop videoconferencing allows video calls, data transfer, and screen-sharing
between two PCs equipped with compatible hardware and software. Most
systems provide extensive menu- and mouse-driven interfaces with options for
call control. Desktop videoconferencing systems use ISDN/BRI interfaces.
With stand-alone configuration, only the desktop video system is attached to the
MLX port. The desktop video system always has full access to two B-channels in
its connection to the MERLIN LEGEND Communications System. Therefore, it
always has the capability to make and receive 2B data video calls.
