Feature Reference
NOTE:
Fast flashing is not applicable for extension types other than individual. Slow
flashing is not applicable for extension types other than individual and line/trunk
number.
Calling Group or CMS Supervisory Operation
A supervisor with a DLC switches from normal call handling to supervisor
operation by pressing the Feature button, dialing
button. The effect of pressing a DSS button while in supervisor operation is the
same as that described for normal call-handling operation. See "Group Calling"
for additional information.
When the supervisory position is not in Message Status operation (the green
LED next to the Message Status button is off), the red LED next to each DSS
button for a calling group member's extension is used to monitor the availability
of members to take calls directed to the calling group. The meaning of the red
LED associated with each group member is shown in Table 12.

NOTE:
The LEDs next to DSS buttons for all other types of extensions are always off
and have no meaning.
Extension Status Operation (Hotel
Configuration)
When Extension Status is in Hotel configuration, the Extension Status feature is
assigned to and removed from individual DLCs through system programming
(see "Extension Status" for details). Hotel Extension Status operation is always
active unless the operator presses the Message Status button to use the Auto
Dial or DSS buttons to see message-waiting status for each extension. Pressing
a DSS button while in Hotel Extension Status operation has the same effect as
for normal call-handling operations.
Meaning
The extension is signed out from the group, and the
member is unavailable to take calls.
The extension is signed into the group, and calls can
be sent to the member.
Used for CMS only: the extension is in the after-call
work state, and the group member is not available to
take calls.
