Line Buttons on Multiline Telephones

Different models of telephones, of course, have different imprinted buttons. The
descriptions above summarized these buttons. Line buttons on multiline
telephones fall into two categories:
Buttons that are system-programmed to access an inside or outside line
or pool of outside lines
Blank line buttons that can be programmed—by the system manager
only, or by either the system manager or the user—with system features
Buttons are different on Queued Call Consoles (QCCs), and you can read more
about them later in this chapter. Direct-Line Consoles are similar to other MLX
display telephones, but there are differences that are also described later in this
chapter.
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 will automatically have 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.
(Chapter 2, "About the System," explains 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
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).
