When the operator presses a DSS button representing an extension
number, the extension label, if any, and the extension number are
shown on the display while it is dialed. When the operator presses the
Page button after pressing the Inspct button, the display shows
the page number selected, and the first extension number in the range.
When the operator presses the Message Status button after pressing
the Inspct button, the display shows
the DSS is in message status operation.
When the operator presses a DSS button representing an extension
number after pressing the Inspct button, the display shows the
extension label, extension number, number of messages, and for
Release 2.0 and later, any posted messages.
In Release 2.0 and later, an operator can check the status of an
extension whose red LED is on by using the Inspct button to determine
whether the extension is busy or using Do Not Disturb. If the user at the
extension is using Do Not Disturb, the Do Not Disturb message is also
posted and appears on the operator's display. (However, the message
may also mean that the user has posted the message without turning on
the Do Not Disturb feature.)
A calling group, CMS supervisor, or an operator at a DLC with Extension
Status assigned can change the status of a group member or room by
pressing a programmed Available or Unavailable extension status
button and then pressing the DSS button for the group member or room.
Activate Forwarding by pressing a programmed button or using a
feature code and then pressing a DSS button for the extension where
calls should go. Activate Follow Me by using the feature code and then
pressing a DSS button for the sender's extension number.
The DSS button's LED for a calling group extension number indicates
the status of calls in the calling group queue. The LED is on when calls
are at or above the programmed threshold and off when the number is
below the threshold.
When One-Touch Hold is programmed, only outside callers are
automatically put on hold when a DSS button for a user, calling group,
or paging group is pressed while another call is active. For an inside
caller, pressing a DSS button for a user sends a manual signal to the
user's extension; pressing a DSS button for a calling group or paging
group has no effect.
