Extension Status capability can be assigned to DLCs only. In hotel
configuration, only a DLC operator can change an extension to Status 0.
In the Group Calling/Call Management System configuration, a calling
group or CMS supervisor uses a DLC to monitor and change group
member status.
A DLC operator can forward calls to extensions and, if the capability is
assigned in system programming, to outside telephone numbers. In Key
mode, because outside lines are assigned as personal line buttons on
the console, the ability to forward calls received on each outside line
(excluding loop-start trunks with unreliable disconnect) to an outside
number must also be assigned in system programming; it can be
assigned to only one telephone for each individual trunk. In addition, the
DLC must be designated as the principal user. In Hybrid/PBX mode, it
can be assigned to multiple telephones for each pool.
A DLC can be a member of a calling group and is used in the calling
group supervisor position.
When programmed systemwide, DLC Operator Automatic Hold puts an
active call on hold when the DLC operator presses another line button.
When One-Touch Hold is programmed systemwide, pressing an Auto
Dial button or DSS button also puts an active outside call on hold. This
prevents accidental disconnection of callers and speeds call handling.
If a call is on hold, the DLC operator hears an abbreviated ring as a
reminder every time the interval programmed for the operator hold timer
(10–255 seconds) expires.
The Send/Remove Message feature is only for operators. It is used by a
DLC operator to turn on the Message LED to indicate that a message is
waiting. For telephones without a display, Send/Remove Message is the
only way the Message LED can be turned on and off by operators. The
Send/Remove Message button is factory-assigned to analog DLCs on
button 34. The Send/Remove Message button is replaced with line 32
when the system has more than 29 lines. Send/Remove Message is not
a fixed feature and can be assigned to any available button on an
analog or MLX DLC.
An MFM cannot be assigned as a DLC position.
A Night Service button is assigned to operator consoles only and is
used by a DLC operator to activate and deactivate Night Service. A
Night Service button is factory-assigned to analog DLCs on button 31.
On a system with more than 29 lines, the Night Service button is
replaced with line 31. The Night Service button is not a fixed feature
and can be assigned to any available button on an analog or MLX DLC.
