DX-120 Installation and Maintenance Manual OVERVIEW
DSS Console (continued)
• The DSS has 64 programmable buttons with dual color (red / green) LEDs and may be assigned any system
feature code or directory number. These buttons may be assigned for either system features operations or
CO line access operations.
• You can mount the DSS console in one of three positions: low and low profile desk positions and the wall
mounted position. DSS consoles are programmed to operate with an associated speakerphone.
• You can assign up to four DSS consoles per speakerphone. The maximum number of DSS consoles
supported by the DX-120 is 12.
• Each equipped DSS console requires one digital port, therefore the total number (system capacity) of
speakerphones possible is reduced by one for each DSS console installed.
