Direct Station Selector (DSS)

You can also have one or two Direct Station Selectors (DSSs) connected to the system
programming console. Each DSS adds 50 extension buttons to the console, which facilitates
assigning features to extensions. The DSS for the 4424LD+ console is the DSS 4450 shown in
Figure 2-3.
The LEDs on the DSS indicate the status of telephone features during system programming, such
as calling restrictions. Each LED on the DSS represents an extension connected to the system.
When certain features are selected from the System Programming menu, the LEDs on the DSS
indicate the status of the feature for each extension. For example, if Restriction is selected from
the Extension menu, the red LED is on for each extension that is toll-restricted.
The LEDs on a DSS change during programming:
If a local extension is busy because features are being assigned through system or centralized
I
telephone programming, the red LED next to the associated DSS button is on to indicate the
busy condition. This occurs when the telephone with the attached DSS is not the one being
programmed.
When you are using a telephone with an attached DSS to program itself or another extension,
I
all but the bottom two rows of LEDs on the DSS turn off during programming mode. The
bottom two rows remain unchanged.
