Data calls cannot be put on hold.
2B data video calls require both B-channels at a video workstation. For
this reason, if a call is on hold 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.
Terminal adapters can use Last Number Dial by dialing the Last Number
Dial feature code. Last Number Dial can be activated by video systems
that can dial strings and feature codes that begin with #.
Messaging features are not available for data or video extensions, but
they can be used by telephones at these workstations.
An MFM cannot be used to connect a digital communications device or
videoconferencing system.
If a digital communications device or videoconferencing system is a
member of the Night Service group, voice calls to the Night Service group
do not ring at these extensions. Data or video calls do ring, and 2B data
calls can be established. However, if there are two or more 2B data
extensions receiving Night Service calls, the two 1B data calls that form a
2B data call may be directed to different extensions instead of the same
one during Night Service operation.
Digital communications devices and videoconferencing systems can be
assigned to paging groups. However, they should not be: they are not
alerted if there is a call to a paging group, and they cannot make group
pages.
Data calls cannot be parked.
Personal lines can be assigned to digital communications devices and
videoconferencing systems, which ideally should not share personal lines
except with extensions at the same workstations. If they do share
personal lines, 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.
When a personal line is shared between a digital data device and a
telephone, voice calls are directed only to the telephone, and data calls
are received only by the digital communications device.
Personal lines can be shared between an MLX telephone and a desktop
video system in passive-bus configuration. 2B data calls can be
completed in this situation.
Personal lines can also be shared between an MLX telephone and a
digital communications device connected to the MLX adjunct extension,
provided that the communications device supports this capability.
A digital communications device can pick up a data call. Pickup is not
recommended at video system extensions, although it can be used at a
passive-bus MLX telephone.
