Digital Data Calls
Personal Lines
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.
Pickup
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.
Pools
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
Privacy is activated automatically for digital data calls.
Reminder Service
Digital communications devices and videoconferencing systems cannot
receive reminder calls.
Remote Access
Data calls cannot be made into lines programmed for remote access.
Ringing Options
Personalized ringing has no effect on digital data calls.
Some terminal adapters follow programmed ringing options and should
be set to Immediate Ring.
Videoconferencing systems are not affected by ringing options.
Signal/Notify
Signaling can be activated by video systems that have the ability to dial
strings and feature codes beginning with #.
A Notify signal can be received at a passive-bus MLX telephone, even
when a 2B data or voice call is active.
Speed Dial
Personal and System Speed dial codes can be used on digital
communications equipment (DCE).
Speed Dial codes can be used only on digital video systems that have the
ability to dial feature codes or number strings beginning with
#
.
System Access/
Intercom Buttons
Data calls cannot be presented as voice calls, although digital equipment
can make calls using ICOM or SA Voice Announce buttons.
