Direct Station Selection (DSS) Buttons

System Availability: All systems

[DSS] buttons can be placed on digital and IP telephones, add-on modules and DSS consoles. When placed on one of these devices, these buttons serve two functions: to make direct calls or transfer calls to other stations; and to display the status of other stations and [PDNs].

The [DSS] button is numbered with a station’s [PDN] and when pressed, calls that [PDN]. [DSS] buttons are not [DN] buttons, so they do not provide dial tone when pressed. The [DSS] button LED shows the status of the station and [PDN] it represents (idle, busy, DND or ringing). The [DSS] LED will turn on steady or flash at a unique rate, depending on the status (see “[DSS] Button Status Display.”

The [DSS] LED displays the telephone’s status for any type of call on any button, including [PhDN] and Line buttons. The [DSS] LED also indicates the status of the station’s [PDN] itself. If the [PDN] appears as a Secondary DN [SDN] on multiple telephones, the DSS status will display Busy if any telephone is using the [SDN].
