In order to use the 2B Data feature, the video workstation's MLX port must be
programmed for the feature. An extension jack programmed as a QCC position
(Hybrid/PBX mode only) cannot be programmed for 2B data and used by a
desktop or ISDN group videoconferencing workstation. Extensions for MFMs (or
data communications equipment not supporting 2B data, such as ISDN terminal
adapters) cannot be programmed for data and should not be connected to 2B
data ports.
For programming details, see System Programming.
Personal lines can be assigned to videoconferencing systems. It is best
for these extensions to have exclusive use of their own personal lines; if
they do not, the system manager should ensure that enough idle lines are
available, particularly when a video system is receiving 2B data calls.
Otherwise, the video system may receive only 1B data while another
extension is using a second personal line.
Personal lines are shared between an MLX telephone and a desktop
video system in passive-bus configuration. 2B data calls can be
completed in this situation.
Pickup is not recommended at video system extensions, although it can
be used at a passive-bus MLX telephone.
If a videoconferencing system is programmed to have a single Pool
button, two calls to that pool result in a 1B data call. However, if two
separate pools are assigned to a videoconferencing system extension,
then a 2B data call can be established. If a system includes two or more
video systems sharing the same pools, incoming 2B data calls can be
misrouted.
Privacy is activated automatically for video calls.
Videoconferencing systems cannot receive reminder calls.
Video calls cannot be made into lines programmed for remote access.
Personalized Ringing and ringing options have no effect on calls to a
videoconferencing system.
Speed Dial codes can be used only on digital video systems that have the
ability to dial feature codes or number strings beginning with
2B data video calls require both B-channels at a video workstation. For
this reason, if a call is on hold for transfer at a passive-bus MLX telephone
when a 2B call comes in, the passive-bus MLX telephone cannot retrieve
the held call until the 2B video call is over.
At a passive-bus MLX telephone, Voice Announce to Busy requires one
of the B-channels needed for a 2B video call and should be used only
when the video system is not active on or receiving a call.
