Direct Station Selection 2 - 2 - AT&T SYSTEM 25 Manual

This feature applies to multiline voice terminals only.
The Direct Station Selection (DSS) feature provides one-button access to another voice
terminal, a pooled facility, a paging zone, or a Direct Group Calling (DGC) group. There are
two types of DSS buttons—Fixed and Flexible. Fixed DSS buttons (DSS) contain PDCs or
access codes (maximum of four digits) programmed by the System Administrator. Flexible
DSS buttons (FLEX DSS) are programmed by the voice terminal user with frequently called
PDCs and other System 25 access codes. If the green light is on next to these types of
buttons, the user can activate a busy-to-idle reminder. This reminder lets the user know
when the call can be made.
A PDC can be programmed on a FLEX DSS button, but an attempt to program an FPDC on a
FLEX DSS button results in Reorder Tone. A pooled facility access code cannot be stored on
a DSS button, but may be stored on a FLEX DSS button. If so, the FLEX DSS button will
function very much like a Direct Facility Access button, with the capability of receiving a
busy-to-idle reminder for the pooled facility. However, this button will not allow access to a
dial-restricted facility.
If the paging zone(s) is administered to be dial restricted, users assigned DSS buttons with
paging access codes can still access the paging equipment.
For instructions on storing FLEX DSS numbers, see the entry for "Programming
on page 2-79.
