AT&T System 25 - Manual (Page 7)

Loop Buttons
Voice communications paths between your console and the
System 25 are called loops. Your console receives calls one at a
time; if you are busy with a call, other incoming calls will wait in
a line (a “queue”) until you are ready to respond. If there are
two attendants they share the same queue.
Your SLAC has five buttons that are used to place and
LOOP
receive calls. These buttons give you access to outside lines as
well as system features.
Automatic Loop Selection
When an incoming call rings, lift the handset (go off-hook); you
are automatically connected to the caller. If your console is idle
and you want to place a call, lift the handset; you automatically
receive dial tone at one of the
LOOP
buttons.
Occasionally, you may have to press a
LOOP
button when you
answer or place a call. The console procedures
instructions when this is necessary.
Selector Console
The Selector Console allows you to call an inside number by
pressing only one or two buttons instead of dialing all the digits.
These buttons are identified and described below.
Group Select Buttons (the first seven buttons located on the
bottom row)
Used for selecting the “hundreds” group of each extension
number.
NOTE: You

Direct Extension Selection (DXS) Buttons (located directly
above the Group Select buttons)
Used for selecting specific extension numbers. (The numbering
is fixed from 00 to 99.)
