Behind Switch - AT&T MERLIN LEGEND Release 4.0 Feature Reference

Feature Reference
Operator park zone codes must be included in the extension number range
specified for one of the Page buttons.
If an extension is busy because features are being assigned through system or
centralized telephone programming, the red LED next to the associated DSS
button is on to indicate the busy condition.
For a QCC only, while active on a call, pressing the DSS button for a trunk
number, Listed Directory Number, or unassigned extension number is ignored.
In Release 2.1 and later, when a call is forwarded to a multiline telephone that
has a DSS button for the forwarding telephone, the light next to the DSS button
does not flash.
DSSs that are out of the building require local power. Any console with two
DSSs require local power.

Direct Voice Mail
The LED next to a DSS button for the ARS code is always off.
After making a call to an extension by using a DSS button on a DLC,
activate Barge-In by pressing a programmed Barge-In button. QCC
operators select the feature from the display.
When Camp-On is used to complete a call transfer and the call returns,
the LED of the DSS button associated with the extension transfer
destination stays off and does not flash, as it does for a transfer return.
On a Queued Call Console, the Direct Voice Mail button is a fixed button
(the right-most button in the second row from the bottom on the DSS) on
a DSS connected to a QCC.
