Programming Feature

Description

Direct Station Selector

One or two DSSs can be used with the 4424LD+ or MLX-20L telephone. (The DSS for the 4424LD+ telephone is the DSS 4450.) Each DSS adds 50 buttons to the system programming console. For more information about the DSS, see Direct Station Selector.

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 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, all but the bottom two rows of LEDs on the DSS turn off during programming mode. The bottom two rows remain unchanged.
  
  
• When you program a telephone with an attached DSS from another extension, all the LEDs on the DSS turn off, including the bottom two rows, during programming mode.
