Introduction
GENERAL DESCRIPTION
Toshiba digital telephones incorporate state-of-the-art
telecommunications technology and provide a vast array of calling
features. They are easy to operate, and all features are accessed with a
feature button or a brief access code.
PURPOSE
This document is designed as a guide to using the 2000-series and the
older 1000-series digital telephones for the STRATA DK24, DK56, and
DK96 systems.
Feature operations in this guide use the button designations for the
2000-series models. Refer to Appendix A for 1000-series designations.
The following telephone models belong to the 2000-series and are
depicted in Figure I-2:
■DKT2010-H ( 10-button model that allows users to answer intercom
calls without lifting the handset)
■DKT2010-SD ( 10-button model equipped with a Liquid Crystal
Display (LCD) and a speakerphone which allows users to make and
receive outside and intercom calls without lifting the handset)
■DKT2020-S ( 20-button model which allows users to make and
receive outside and intercom calls without lifting the handset)
■DKT2020-SD ( 20-button model equipped with an LCD, and a
speakerphone which allows users to make and receive outside and
intercom calls without lifting the handset)
The following telephones comprise the 1000-series:
■DKT1010-H ( 10-button model that allows users to answer intercom
calls without lifting the handset)
■DKT1020-SD ( 20-button model equipped with an LCD, and a
speakerphone which allows users to make and receive outside and
intercom calls without lifting the handset)
This user guide covers all of the voice calling features, such as Call
Holding and Call Forward, available with each of the phones.
Your digital telephone may have an LCD for message and feature
information and/or a data interface unit for data calling. Refer to the
Digital Telephone LCD User Guide and the Data Interface User Guide to
operate these options.

ORGANIZATION
This user guide is divided into the following sections.
The Introduction consists of a general description of the digital
telephones as well as the purpose and organization of this document.
Suggestions on how to use the user guide also appear in this section.
Chapter 1, "General Information," provides descriptions of the functions
of all the feature buttons along with their associated Light Emitting
Diodes (LEDs) available to the telephones.
Chapter 2, "Feature Operation," contains descriptions and operating
procedures for all of the voice calling features offered by the telephones.
Chapter 3, "Toshiba VP Integration," explains how to set up your
telephone to forward calls to a Toshiba Voice Processing System and to
retrieve recorded messages left by callers.
Chapter 4, "Centrex Application," describes the Centrex features which
may be available with your STRATA DK system.
Appendix A provides a list of the feature button designations of the 1000-
series models.
Appendix B provides space to record customized feature access codes,
Speed Dial numbers, and more.
A glossary and an index are located at the end of the user guide.
HOW TO USE THIS GUIDE
Most of the features in this guide are available with your telephone. Your
system administrator can tell you which features you can access.
The information in this user guide is divided into distinct areas of content.
Instructions for various procedures are referred to as Action Text and
appear in the left-hand column of the page. Instructions appear in
numerical sequence, enabling you to quickly perform a specific task.
More detailed descriptions of these procedures, or explanations of their
effects, are located in the right-hand column. Figure I-1 shows you the
structure followed for each feature operation.

To Override a Call:
1. Press a busy Line button.
To Make All CO Lines on Your
Station Private:
1. Press the Privacy on Line
button.
To Cancel Privacy:
1. Press the Privacy on Line
button again.
PRIVACY OVERRIDE
This optional feature allows you to enter an established call on a private
common CO line button. Up to two station users may enter an existing
CO line-to-station call (allowing up to three stations to be connected to a
CO line). To access this feature, your station must be assigned with
Privacy Override in system programming, or the station that is already
connected to the CO line must be in the Privacy Release mode.
You will now be connected to the CO line, and will be able to participate
in the conversation.
An optional tone signal may be heard by the connected parties before
you enter the conversation.
NOTE:
Station users with a Privacy Release button can allow stations to enter
their conversations on common Line buttons, even if the station entering
the conversation is not programmed for Privacy Override.
PRIVACY BUTTON
This option blocks a user at a station programmed with Privacy Override
from entering a CO line conversation by pressing a common CO line
button. Your station must be assigned with the Privacy on Line button in
system programming to activate this feature, which will not block Busy
Override or Executive Override. Busy and Executive Override are
described later in this guide.
After you press the button, the Privacy on Line LED will light steady red,
and station users will not be able to enter CO line calls on your station
with Privacy Override.
The Privacy on Line LED will turn off, and station users will now be able
to enter CO line calls on your station with Privacy Override.
