Digital Data Calls
Applications
9
The high-speed data capabilities of the MERLIN LEGEND Communications
System can be used for a number of applications, including videoconferencing,
Internet access, and data transfer.
Depending upon its capabilities, a videoconferencing system may offer
application-sharing, video collaboration, and data-sharing on either one or two
data channels at a time (most video systems require two channels). If one
channel is used, the maximum data speed is 64 kbps; if two channels are used,
the maximum data speed is 128 kbps.

Queued Call Consoles
9
Queued Call Consoles cannot be programmed for 2B data. If a DLC is
programmed for 2B data, the DLC cannot be changed to a QCC unless 2B data
programming is first removed from the DLC.
Feature Interactions
9
Account Code Entry
Account Code Entry can be entered for calls made by digital data
workstations and by video systems that support the use of # for feature
codes. The account code must be entered before the telephone number.
Authorization Code
Data calls can use authorization calls. If Account Code Entry is also used,
the authorization code must be entered after the account code.
Authorization codes can be used by video systems that support the use of
# for feature codes.
Auto Dial
A terminal adapter can make a call using an Auto Dial button by dialing
the virtual number of the button (for example
#01
). A video system that
supports the use of 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
9
) followed by the
telephone number. Data calls
must
be routed through ARS pools that
access only PRI, NI-1 BRI, and/or Switched 56 T1 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.
