Auto Dial A terminal adapter can make a call using an Auto Dial button by dialing
the virtual number of the button (for example
). A video system that
supports entering # for feature codes can use Auto Dial in the same
fashion.
Automatic Route
Selection
Data calls can be made using ARS. To make calls using ARS, digital
devices simply dial the ARS dial-out code (usually
) followed by the
telephone number. Data calls
must
be routed through ARS pools that
access only PRI, NI-1 BRI, and/or T1 Switched 56 data lines. To make a
2B data call, a user must make two calls on different lines.
Barge-In Data calls cannot be barged into.
Call Waiting Call Waiting does not work on data calls. A call appears to wait but does
not return to the extension when it becomes available. This feature should
be disabled at video systems and data extensions.
At a passive-bus MLX telephone, Call Waiting 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.
Callback Videoconferencing systems that can dial feature codes using # can use
Selective Callback. When a pooled line becomes available or the busy
video system is idle, the queued call is made, one B-channel at a time.
When the second B-channel becomes available, it can be used for the
connection as well, providing the video system supports this capability.
Although video systems can use either off-hook or on-hook Callback, you
should only use off-hook Callback for 2B data connections. If you use
on-hook Callback, the returning callback call is connected using only one
B-channel.
Automatic Callback should be disabled for digital data and
videoconferencing extensions. It can be used at MLX passive-bus
extensions at desktop video workstations.
Camp-On You cannot camp onto data or video calls.
Conference Conference does not function with data calls.
2B data video calls require both B-channels at a video workstation. For
this reason, if a call is on hold for conferencing 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.
