DSS (Direct Station Selection) Console The DSS console is a digitally interfaced component of the DX-80. It connects to the system via any available digital port (408M/E or DPM8 digital port). The DSS is equipped with 60 programmable buttons. Twelve of these buttons are intended for features code storage only and do not have LED indications associated with them. Forty eight buttons are equipped 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 two positions: lower profile desk position and 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-80 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
