AT&T System 25 Telephone User Manual


 
Direct Station Selection (DSS)
DSS buttons allow numbers to be stored in the memory system
so you can make calls without dialing the digits. There are two
kinds of DSS buttons: fixed and flexible. Fixed DSS buttons,
DSS , are extension numbers or access codes programmed by
the System Administrator.
Flexible DSS buttons, FLEX DSS ,
allow
you
to program extensions and other System 25 access
codes. (You cannot program Pooled Facility Access codes on a
DSS button.)
For instructions on how to program information in FLEX DSS
buttons, see the section titled “Programming Numbers”.
