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
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
employing a variety of visual aids, including interactive writing and drawing,
prepared text and graphic materials, and prerecorded audio and video material.
You can have all the advantages of face-to-face meetings while decreasing your
travel budget.
Group video systems that support ISDN/BRI interfaces have built-in data
communications devices and can use one MLX B-channel or two (depending on
the system), requiring only a single MLX jack and the system's 2B Data feature.
Older group systems that support a V.35 interface may also have built-in data
communications devices; if not, they require two Lucent Technologies-certified
ISDN terminal adapters, or an inverse multiplexor and two MLX ports. V.35
systems use two adjunct extension numbers.
Most group videoconferencing applications include an easy-to-use control
console that allows you to conduct the conference as easily as you operate a
telephone. It includes superior camera optics and digital audio signals.
The components of a group video system can be integrated on a mobile console
that rolls easily into a conference room prior to a scheduled video conference call.
Alternatively, some companies build their systems into a videoconferencing room.
CTI (Computer Telephony Integration) Link
Beginning with Release 5.0, the system supports the CTI (Computer Telephony
Integration) link, which allows the use of software applications with the system.
Although the CTI link is not, strictly speaking, a feature, it enables considerable
feature enhancement to the system. Available in Hybrid/PBX mode, this capability
connects the system to a PassageWay Telephony Services product on a local
