About Your Direct-Line Console
Line and DSS Buttons
Your console’s line buttons and/or DSS buttons are
preprogrammed and labeled for specific functions,
depending on the way your system has been configured.
Line Buttons
The MLX-20L telephone has 20 line buttons and the MLX-28D
telephone has 28 line buttons. You use these buttons to
make and receive calls. Any button not assigned as a line
button can be programmed for one-step feature use. Two or
more of your line buttons are programmed as either Intercom
(ICOM) or System Access (SA) buttons. You cannot have
both.
ICOM and SA buttons provide two options for call
announcement, depending on how they are labeled:
■
Ring –makes the telephone ring at the destination
extension.
■
Voice –turns on the speaker at the destination
extension so you can start speaking immediately.
You can also have an SA or ICOM button designated Orig
Only (Originate Only). These buttons are used only to make
calls. Not all consoles provide this button.
