Line Selection - AT&T SYSTEM 25 User Manual

Each Multiline voice terminal has at least two System Access
buttons that can be used to place and receive calls. From these
buttons you can also gain access to outside lines and system
features. On most terminals, these buttons are located in the
upper left portion of the faceplate, and are labeled with your
PDC (extension number). Unless otherwise noted, you must use a
System Access button for the procedures described in this manual.

Line Selection

If your voice terminal automatically selects a line when you lift
the handset to place a call, you have the option "prime line
preference." If your voice terminal automatically selects the
ringing line when you lift the handset to answer a call, you have
the option "ringing line preference. "
Throughout this manual, it has been assumed that you
both ringing line preference and prime line preference (on a
System Access button). If you do not have these options, the
appropriate line (button) must be manually selected at the beginning of
most procedures.
