AT&T AT&T manual Access to Paging Zones and DGC Groups, 130

DIRECT STATION SELECTION (DSS)

Description

Allows one-button access to another voice terminal, a paging zone, or a DGC Group. This feature requires a button assignment on a multiline voice terminal.

There are two types of DSS buttons. Numbers stored on DSS buttons (maximum of four digits) are programmed at the SAT; numbers stored on Flexible DSS buttons (maximum of four digits) are programmed at the voice terminal. The procedure for programming FLEX DSS buttons is provided in the “Program’’ feature description.

To use DSS, the user presses DSS or FLEX DSS and goes off-hook. The caller hears Ringback Tone. DSS calls to a multiline voice terminal are received on a System Access button. The DSS status LED is lighted steadily at the calling station.

The DSS status LED is lighted whenever the pointed-to station is off-hook. The user may press DSS and remain on-hook to receive the busy-to-idle reminder. The user’s voice terminal will ring once when the other party hangs up; lifting the handset will automatically place the call.

When Prime Line Preference is assigned to invoke the busy-to-idle reminder, even though

a DSS button, the button must be pressed to the I-Use LED is lighted.

Access to Paging Zones and DGC Groups:

Access is provided to an individual Paging Zone or to all paging zones or to a DGC group. The status and busy-to-idle reminder indication described above also apply to DGC groups with the understanding that they are busy if all the members are busy.

Considerations

Direct Station Selection differs from Automatic Intercom in that it provides one-button access from one voice terminal to another (one-way only), while Automatic Intercom provides similar access for each voice terminal (two-way) and must be assigned between two multiline voice terminals. A DSS button may point to a single-line station; an Automatic Intercom button may not. DSS calls receive call coverage, Automatic Intercom calls do not.

Interactions

●Call Coverage: DSS calls placed to an individual with Call Coverage will receive standard call coverage treatment.

●Call Following: For Vl systems, DSS calls do not follow users who log in at other

voice terminals. For V2 systems, DSS calls do receive Call Forwarding treatment.

●Direct Group Calling: A DSS button can be assigned to a DGC group. The

associated LED lights steadily when all stations in the group are busy.

●Last Number Dialed (V2): Numbers called by pressing FLEX DSS or DSS buttons are not saved by Last Number Dialed and cannot be recalled with that feature.
