The system automatically assigns line buttons to each multiline telephone. You
can add, remove, or change this assignment through centralized telephone
programming, but every multiline telephone automatically has two ICOM
(Intercom) or three SA (System Access) buttons assigned. Whether your system
has ICOM buttons or SA buttons depends on the system’s operating mode (see
“Modes of Operation” on page 2–16 for more information about modes).
NOTE:
The system automatically assigns two ICOM or SA buttons to single-line
telephones. Even though the telephone allows only one line, the extra
assigned button permits the use of features that require two line buttons
(for example, Transfer). In Release 4.0 and later systems only, the system
manager can remove one line button assigned to a single-line telephone.
This disables Transfer, Park, Account Codes, Pickup, Call Waiting,
Conference, Extension Status, and Privacy.
Key Mode Line Buttons 3
When the system operates in Key mode, you can program two different kinds of
line buttons for making and receiving calls:
■ Line Buttons (or Keys). These buttons are associated with specific outside
lines for making or receiving calls to telephone numbers other than system
extensions (“outside” the system). Line buttons allow you to see activity on
other telephones, join conversations, and make and receive calls.
■ ICOM Buttons. These buttons allow you to make and receive inside calls
to or from system extension numbers (“inside” the system).
ICOM buttons fall into several categories:
■ ICOM Ring. Use this button to make inside calls and to receive inside and
outside calls transferred from another extension. When you use an ICOM
Ring button to make an inside call, the telephone at the destination
extension rings once per ring cycle to indicate an inside call.
■ ICOM Voice. Use this button to make inside calls and to receive inside and
outside calls transferred from another extension. When you use ICOM
Voice to make an inside call, the user at the destination extension hears
the caller’s voice on the speakerphone after a beep that replaces ringing.
(If you are using an ICOM Voice button to make a voice-announced call
and the user at the destination extension has a single-line telephone or a
telephone that does not have a speakerphone, or has disabled voice
announcements, the telephone rings just as if the call was made on an
ICOM Ring button.)
■ ICOM Originate Only. Use this button to make inside calls. You cannot
receive inside or outside calls on ICOM Originate Only buttons. This type
of button ensures that you always have a button available to make or
