A Do Not Disturb button should be programmed at MLX passive-bus
telephones, and the feature should be activated during 2B video calls.
Otherwise, voice calls ring and flash at the MLX telephone during 2B data
calls, although they cannot be answered.
The use of Do Not Disturb at a passive-bus MLX telephone allows voice
calls to be covered while 2B video calls are in progress.
Digital communications devices can forward calls by dialing the
associated feature code.
Forward can be activated by video systems that have the ability to dial
strings and feature codes beginning with #. 2B data calls are forwarded
as two 1B data calls.
Remote Call Forwarding is not available at video system extensions.
Lines intended for data calls should not be mixed in the same calling
group with lines intended for voice calls.
Video systems can connect only using 1B data connections (providing the
video application supports 1B data) when receiving a call through a
calling group (called a Data Hunt Group when used for data calls)
because a calling group dispenses only one call to each calling group
member.
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 beginning 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.
