Strata DK PC/Data Interface 5/99 1
The Grand Tour 1
Toshiba provides two interface units that integrate the Strata DK telephone system
with PCs, printers, and modems for a variety of applications.
The Stand-alone Data Interface Units (PDIU-DS) normally connects to printers and
modems so that they can be shared by all users via data calls through the DK
telephone system.
The telephone PC Interface Unit (RPCI-DI) is built into the base of the digital
telephone and connects to the COM port of a PC. There are two operating modes:
♦Telephone Application Program Interface (TAPI) mode
♦Data communication mode
The PC TAPI software program automatically controls the operation mode (TAPI or
Data Communications) of the RPCI.
A 2B+D ISDN-type digital link in conjunction with the RCPIs and 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 you several
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 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 RPCI-DI and PDIU-DS types.
The Grand Tour
Hardware Requirements

Features 2
This chapter explains how to use your data telephone to connect to other data devices,
such as an internal printer, modem pool, or mainframe computer. It also explains how
to originate and answer simultaneous voice and data transmissions from your
telephone or another telephone.
Data Call to Internal Printer or Other Data Device
If using a PC, data calls to printers can be connected anytime while running a word
processor, spread sheet, or database program. This procedure can also be used to make
data calls to other internal data devices, such as modems or mainframe computers, that
are connected to stand-alone DIUs. A communications software program is generally
required for these types of internal data calls.
Before making your call, verify that the communication parameters of your PC or
terminal match those of the printer or data device you are calling.

Personal Computer Dialing of Voice Calls
28 Strata DK PC/Data Interface 5/99
Dialing programs vary, but most require that you enter the telephone number to be
called in a designated field or space. When using a Toshiba Data Telephone you must
also enter the outgoing call access code in front of the telephone number to be called.
Example: If the telephone number is 1-714-583-3700, the following sequence should
be entered in the telephone number field:
CO Line Access Code + 17145833700
When the CO line access code and telephone number is entered into the dialing field
properly and the computer software dialing is initiated, the PC automatically sends the
following sequence to the Data Telephone:
ATDT + CO Line Access Code + 17145833700
Note ATDT is the Hayes modem dialing command automatically inserted by the
computer dialing software.
When the Data Telephone receives the above dialing command, it automatically
accesses an outgoing CO line and dials 17145833700. The Data Telephone’s [DN]
or CO line button LED turns ON (green), and its LCD (if equipped) displays the
dialed digits.

This chapter contains advanced information for the sophisticated data communication
user. The contents are not required for typical operation.
Data Communications Mode
When in the Data Communications mode, the RPCI and DIU can operate in either the
Command Mode or the Communication Mode. All the dialing, answering, and
disconnecting activities related to a data call take place during the command mode
using standard Hayes “AT” commands. The actual data operation—file transferring,
printing, etc.—takes place during the communication mode.
Switching Between Data Communications and TAPI Modes
The PC software normally controls the RPCI operating mode (TAPI or DATA). To
switch between modes, the PC software or manual keyboard must send the following
chapters to the RPCI:
♦When in the TAPI mode, send the HEX (FØ), decimal 240, or the ∫ (ASCII
character) to the RPCI to switch it to the Data Communications mode.
(Unplugging the telephone cord and then reconnecting it also resets the RPCI to
the Data Communications mode.)
Mode Definitions
Data Communications Mode
30 Strata DK PC/Data Interface 5/99
♦When in the Data Communications mode, send (ATCØ) to the RPCI to switch it
to the TAPI mode.
♦RPCI mode switching should be performed automatically by the application
programs running on the PC connected to the RPCI-DI.
Data Communications Command Mode
A RPCI or DIU must be told what number to dial, whether to answer, or whether to
disconnect. These instructions, when typed from the keyboard of a PC or terminal, are
called AT commands. A complete list of RPCI or DIU-supported AT commands is
provided in Table 4 on Page 28. RPCIs or DIUs remain in or enter into the Command
Mode when any of the following actions occur.
♦The RPCI and DIU are powered up by connecting it to the Strata DK system via
the modular jack/cord. The RPCI powers up in the Data Communications mode as
opposed to the TAPI mode.
♦The reset (Z) AT command is issued.
♦No carrier is detected while originating or answering a data call.
♦The carrier signal from a remote DIU or modem is lost.
♦A semicolon (;) is entered at the end of the dial (D) command.
♦The escape sequence (+++) is entered while the RPCI or DIU is in the
Communication Mode (on-line mode).
Note Always change the escape sequence of a RPCI-DI connected to your PC to
avoid operation conflicts. Consult the documentation provided by the modem
manufacturer for documentation on the ATS2 command.
Other Command Mode features—Result Codes, Dialing Modifiers, and S-Registers—
are explained below.
Result Codes: Displayed on the terminal or PC screen, Result Codes are RPCI and
DIU responses to AT commands and end-to-end connections and disconnections.
DIUs support the Result Codes in Table 6 on Page 35.
Dialing Modifiers: Dialing Modifiers do exactly what their name indicates. They can
be issued anywhere in the dialing string and provide additional dialing instructions.
Mode Definitions
Data Communications Mode
Strata DK PC/Data Interface 5/99 31
Dialing Modifiers can be used for a variety of applications, including tone dialing, dial
pulse dialing, and pause and flash inserting. DIUs support the Dialing Modifiers listed
in Table 9 on Page 36.
S-Registers: RPCIs and DIUs can be configured for specific applications with S-
Registers, which can only be changed or checked during the Command Mode. When
power is first applied to it and whenever its modular line cord is temporarily
disconnected and then reconnected, the RPCI and DIU initializes the S-Registers to
the default values and enters the Command Mode. DIUs support the S-Registers listed
in Table 7 on Page 35. To check or change an S-Register, refer to the following
procedure:
➤To check the value of an S-Register
➤To change the value of an S-Register
Notes
●A PC must be running communications software or a desk organizer dialing
program (be on-line) to issue AT commands. AT commands cannot be
inputted from a data telephone’s dial pad, a PC DOS prompt, word processor,
database, or spread sheet-type programs.
●AT commands are executed by the DIUs only after the carriage return key is
pressed. The carriage return is referred to as Enter in this guide. On some
keyboards, though, this key may have a different designation, such as
RETURN, <CR>, ENTER, etc.
●All AT commands must be typed as capital letters.
➤Type ATSX? and
press Enter (X is
the S-Register you
want to check).
The value along with the “OK” Result Code is
displayed.
➤Type ATSX=Y and
press Enter (X is
the S-Register you
want to change and Y
is its value).
The S-Register value is now changed, and the screen
displays “OK”. (If the entry is invalid, “ERROR” is
displayed in most cases.)
Mode Definitions
Data Communications Mode
32 Strata DK PC/Data Interface 5/99
●DIUs can operate at up to 19,200 bps with manual dialing from a data
telephone. If keyboard dialing with AT commands, the DIUs can operate at up
to 9600 bps.
Data Communications Mode (On-line state)
A PDIU-DI automatically enters the communication mode when its call to another
DIU is answered. At this point, the desired data operation—file transfer, printing, etc.,
can begin. DIUs remain in the Communications Mode until the data operation is
manually terminated or the escape sequence (see “Switching Between Data
Communication Modes”on Page 32) is issued. A calling PDIU-DI switches to the
Communication Mode from the Command Mode when the following sequences
occur:
♦When the ATD or ATDD command strings are typed and Enter is pressed, the
called DIU answers (manually or automatically).
♦When the ATO command string is typed and Enter is pressed, a DIU-to-DIU
data connection is established (see “Switching Between Data Communication
Modes”on Page 32).
♦When a remote modem issues the ATA command string after the calling DIU
issues the ATD42 command string, a CO line voice call is switched to a data call
using the system modem pool.
Note A called DIU switches to the Communication Mode when it answers,
automatically or manually.
Switching Between Data Communication Modes
Once a PRCI or DIU is connected to another RPCI or DIU and in the Communication
Mode, it can be switched back to the Command Mode with the escape sequence and
then back again to the Communication Mode with the re-enter command. This feature
is helpful when you change a parameter after establishing a data call. Parameters can
only be changed while in the Command Mode.
♦Escape Sequence: To escape from the Communication Mode, hold down the
Shift key and type +++ (it is not necessary to press Enter).
♦Re-enter Sequence: To re-enter the Communication Mode, type ATO and press
Enter.

RPCI/DIU Data Speed (Baud Rate)
DIUs pass data at a baud rate of up to 19,200 bits per second (bps), if the call was
established by manually dialing from a data telephone. If the call was established with
AT commands from a PC or terminal, the DIU passes data at up to 9600 bps. The baud
rate of a DIU is transparent when originating calls with the data telephone or when
receiving data calls, manually and automatically. When originating data calls with AT
commands from a PC or terminal, the DIU speed is the same as the rate of the first AT
command. When answering data calls with the ATA command string, the DIU baud
rate is the same as the command string; the AT command baud rate is determined by
software running the terminal or PC.
RPCI/DIU Default Communication Parameters
Default parameters for the DIUs are shown below; however, they are transparent or
changed by the first AT commands issued, as described above. A DIU assumes these
default parameters when power is initially applied to it, or after the modular cord is
disconnected and then reconnected.
♦Baud rate: 1200 bps
♦Data bits: 8 bits
♦Parity: none
♦Stop bits: 1 stop bit
