Introduction 1
This manual is a compilation of information from several System 25 sources, and is intended
to be used by the System Administrator, AT&T Technical Consultants, and Systems
Technicians. It provides the same instructions for using System 25 voice and data terminals
as found in the Data Features User Guide and in the user guides for System 25 voice terminals.
It also includes information from the System 25 R2V1 Reference Manual.

1-2 Introduction

System 25 Voice Terminal Overview
This section is an overview of System 25 voice terminal operation. It describes the functions
of voice terminal tones, lights, and feature buttons.
Voice Terminals Supported
System 25 supports a maximum of 142 multiline voice terminals in addition to two multilines
assigned as attendant consoles. Of the 142 voice terminals, up to 96 may be 22- or 34-button
types.
Single-Line Terminals System 25 supports both rotary and touch-tone single-line voice
terminals.
Multiline Terminals System 25 supports many models of multiline voice terminals,
including the MERLIN® CS family of multiline voice terminals and
the HORIZON® CS Multibutton Electronic Telephone (MET) voice
terminals.
Attendant Consoles The System 25 supports up to two Direct Trunk Attendant
Consoles (DTACs) or up to two Switched Loop Attendant Consoles
(SLACs). The Direct Extension Selector Console is specifically
designed for use with System 25 attendant consoles.
For further information on specific models of voice terminals supported by System 25, see the
R2V1 Reference Manual.
DDCS and PDCS
When System 25 was installed, Data Dial Codes (DDCs) were assigned to data terminals and
Personal Dial Codes (PDCs) were assigned to voice terminals. In most cases, a PDC is
equivalent to an extension number. Visitors and those who do not have exclusive use of a
voice terminal may have been assigned Floating Personal Dial Codes (FPDCs).
Calling Restrictions
Calling restrictions, such as toll restriction and dial-access restriction, are established on a
per-terminal (not PDC) basis by the System Administrator. Attempts to place calls that
conflict with specified restrictions receive fast busy (reorder) tone at a voice terminal or a
denial message at a data terminal. For further information, see the “Calling Restrictions”
feature description in the R2V1 Reference Manual.

The call is either a callback because the station or outside line requested is now available, or
the call is being set up remotely for this phone via Third-Party Call Setup (a data feature).
(two short rings and one long ring)

System 25 signals users with tones that are heard through the handset. The tones and their
descriptions are listed below.

System 25 Voice Terminal Overview 1-5

Single-Line Voice Terminals
The Switchhook (Recall)
The switchhook is used in single-line voice terminal procedures. The switchhook is the
button(s) pressed down by the handset when not in use. When the user is instructed to
press the switchhook, the switchhook must be pressed down firmly as far as it will go for
approximately 1/2 second and then released. If the switchhook is pressed and released too
quickly, the signal will not work. If the switchhook is held down too long, the call will be
disconnected.
NOTE: If a single-line voice terminal has a [RECALL] button, the user can press it
instead of the switchhook. It does not matter how long this button is held down,
as timing is automatically controlled by the terminal.
To hang up and place another call right away, the switchhook should be held down for more
than two seconds. [RECALL] should not be used to hang up and place another call.
Multiline Voice Terminals and Attendant Consoles
The following information describes special features of multiline voice terminals and
attendant consoles. Attendant consoles have some additional features, exclusive to them,
described later in this section.
Buttons
Buttons, like features, are either fixed or assignable. Fixed buttons, such as [TRANSFER] have
specific permanent functions. Assignable buttons can have features assigned to them, usually
by the System Administrator. Each type of button is represented in a special way in this
manual, as shown below.
TYPE SHOWN AS:
dial pad buttons

dark background buttons with [TRANSFER]
permanent labels (fixed)

NOTE: A fourth type of button can be found on the display unit, and is represented
in the following manner: [ Set ] .
