The use and definition of each DSS button’s LED depend on both the extension
represented by the button and whether the system operator position is used for
normal call handling, Calling Group or CMS Supervisory operation, Extension
Status in Hotel configuration, or Message Status operation. See Extension
Status and Group Calling for additional information.
Normal Call Handling Operation
Normal call handling operation is in effect when the position is not in Message
Status or Extension Status operation. The DSS buttons are used for one-touch
dialing of extension numbers. When a button for a telephone extension, Calling
Group extension, or Paging Group extension is pressed, the extension number
is dialed automatically. In Hybrid/PBX mode, the system operator can either
select a specific pool or dial the ARS code by pressing the DSS button for a
pool dial-out code or ARS code. If a DSS button for any of the extensions or
codes mentioned above is pressed before the handset is lifted, the speaker is
turned on automatically and an SA or ICOM button is selected.
A system operator can also use a DSS button to activate a feature that requires
an extension number—Barge-In, Conference, Send/Remove Message, Forward
(including Remote Call Forward), Follow Me, Leave Word Calling, Reminder
Service, and Transfer. To do this, the system operator presses the Feature
button, dials the feature code, and then presses the DSS button for the
extension number.
The result of pressing a DSS button while on a call depends on the type of
system operator position, the type of button pressed, and whether the system is
programmed for One-Touch Hold or One-Touch Transfer as described in
Table 7 and Table 8. For QCC system operator position, see Table 9.
