Introduction
GENERAL DESCRIPTION
The STRATA DK Data Interface Units (DIUs) provide users with the
capability to execute a wide variety of data call features. This user guide
contains instructions on how to implement these features.
All the features in this guide have practical applications for a diversity of
office environments. Instructions are provided on how to use the DIUs to
connect personal computers together to exchange files, to share a printer
or a modem, to access a mainframe, and more.
Feature operation is are easy and can be accomplished quickly. For the
most part, operation is a matter of pushing some buttons or dialing a
number on the digital telephone and/or issuing a few commands from the
keyboard of a terminal or personal computer.
A 2B+D ISDN-type digital link in conjunction with the DIUs enable digital
telephones to participate in simultaneous voice and data calls. Voice and
data calls are transmitted over the same digital telephone wire pair. This
offers users a number of calling options. For example, a digital telephone
user can place a voice call while in the middle of a data call to a printer or
host computer, etc. This type of call and many more are easily accessed
with the help of this guide.
ORGANIZATION
This user guide is divided into four chapters. Chapter 1 is the
introduction. Chapter 2 provides a description of the DIUs: their function,
controls, and applicable indicators. Chapter 3 contains the calling
procedures.
SUPPORTING DOCUMENTATION

STRATA DK INTRODUCTION

Chapter 1
INTRODUCTION
This chapter lists all the equipment required to originate or receive a data
call. In addition, it explains the function and configuration of the data
interface units (DIUs), both the Integrated-into-the-telephone (PDIU-DI)
and Stand-alone (PDIU-DS) types.
HARDWARE REQUIREMENTS
The following hardware is required to originate a data call:
■A PDIU-DI (replaces digital telephone base)
■A Personal Computer or ASCII Terminal
■One of the following Toshiba 2000- or 1000 Series Digital Telephones:
❏DKT2010-H (10-button model)
❏DKT2010-SD ( 10-button model with a Liquid Crystal Display
(LCD) and speakerphone)
❏DKT2020-S ( 20-button model)
❏DKT2020-SD ( 10-button model equipped with LCD and
speakerphone)
❏DKT1010-H ( 10-button model)
❏DKT1020-SD ( 10-button model equipped with LCD and
speakerphone)
A data call can be made to a device connected to a DIU (PDIU-DI or
PDIU-DS). These devices include the following.
■Mainframe Computers
■Printers
■Modems
■Personal Computers
■ASCII Terminals
INTEGRATED DATA INTERFACE UNIT (PDIU-DI)
A telephone within the STRATA DK system that participates in a data call
must be a Toshiba digital telephone equipped with an integrated DIU
(PDIU-DI). A label reading “MODEL PDIU-DI” on the the bottom of the
telephone and an RS-232 connector on the back of the telephone both
indicate that a telephone is equipped with a PDIU-DI.

NOTE: Throughout this guide, PDIU-DI-equipped digital telephones that
are connected to ASCII terminals or personal computers are referred to
as data telephones.

DATA TELEPHONE (PDIU-DI) BUTTONS AND
LEDS
In system programming, the data telephone can be assigned the
following data feature buttons:
Data Call Button—Enables a digital telephone’s PDIU-DI to be
connected with another DIU in the system when manually dialing from
the telephone. When the DATA CALL button is pressed on an idle data
telephone, the system sends intercom dial tone to the telephone to
prompt dialing. The DATA CALL button also can be used to switch data
telephones and CO lines from voice to data on external calls. The DATA
LED lights when you receive a data call from another data telephone or
when you make a call from your data telephone, personal computer, or
ASCII terminal.The DATA LED will always be red when lit (ON).
Data Release Button—Terminates data calls. The DATA RELEASE LED
never illuminates.
Modem Button—Reserves a system modem for 60 seconds. If a
modem is not accessed within this time limit, press this button again to

reserve for another 60 seconds. The MODEM LED indicates modem
status: a flashing LED indicates that a modem is currently reserved for
your telephone; a steadily lit LED indicates that you have actually
accessed a modem or that all modems are busy. The MODEM LED will
always be red when steadily ON or flashing.
PDIU-DI CONNECTIONS
If a data terminal is connected to a data telephone, the terminal must be
an ASCII type with a standard keyboard and a display screen or printer
display.
If a personal computer is connected to a data telephone, the personal
computer must be running at least one of the following types of
programs: word processor, desk organizer dialer, or communications
software. Also, the personal computer must be active (on-line) on its
COM port connected to the data telephone’s PDIU-DI.
NOTE: It is not possible to establish data call connections from your
personal computer DOS prompt.
The data telephone (PDIU-DI) is connected to the personal computer
serial communications port (COMX, where X = 1, 2, 3, or 4) or terminal
with an RS-232 cable and connector. It is connected to the STRATA DK
system like any other digital telephone with a modular cord.
COMMUNICATION PARAMETERS
Before a data connection is established, the communication
parameters—data speed (baud rate or bps), parity, data bits, stop
bits—of the terminal or personal computer must be the same as the data
device that is calling or being called. To set the personal computer
communication parameters, use the following MS-DOS MODE
commands:
MODE LPT x: =COM x ( x = 1, 2, 3, or 4)
MODE COM x: baud rate , parity , data bits , stop bits , P

Communication Parameter Options
NOTE: In most cases, it is recommended to program the above two
MODE commands into the personal computer’s DOS AUTO EXEC.BAT
file. Also, in most communications software, desktop, and word
processor programs, the COM port number and communication
parameters must be set to allow proper operation of data calls.
