Strata DK PC/Data Interface 5/99 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. Strata DK PC/Data Interface 5/99 1 The Grand Tour Hardware Requirements Hardware Requirements The following hardware is required to originate a data call: ♦ A RPCI-DI (replaces digital telephone base) ♦ A PC 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 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 (RPCI-DI or PDIU-DS), such as mainframe computers, printers, modems, PCs, and ASCII terminals. Integrated Data Interface Unit (RPCI-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 (RPCI-DI). A label reading “MODEL RPCI-DI” on 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 RPCIDI. See Figure 1. Note 2 Throughout this guide, RPCI-DI-equipped digital telephones that are connected to ASCII terminals or PCs are referred to as data telephones.

Table 1 Data Feature Buttons Button DWD DOO Description Enables a connection between the digital telephone’s RPCI-DI to another DIU in the system when manually dialing from the telephone. When DWD DOOis pressed on an idle data telephone, the system sends intercom dial tone to the telephone to prompt dialing. DWD DOOalso can be used to switch data telephones and CO lines from voice to data on external calls. The Data Call LED lights when you receive a data call from another data telephone or when you make a call from your data telephone, PC, or ASCII terminal. The Data Call LED is always red when ON. DWD 5HOHDVH Terminates data calls. The Data Release LED never illuminates. 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. 0 R GHP A flashing Modem LED indicates that a modem is currently reserved for your telephone; a continuously lit LED indicates that you have accessed a modem or that all modems are busy. The Modem LED is always red when ON or flashing. Strata DK PC/Data Interface 5/99 3 The Grand Tour Integrated Data Interface Unit (RPCI-DI) RPCI-DI Data Connections See the Strata DK I&M Manual for detailed installation instructions. 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 PC is connected to a data telephone, the PC must be running at least one of the following types of programs: word processor, desk organizer dialer, or communications software. Also, the PC must be active (on-line) on its COM port connected to the data telephone’s RPCI-DI. Note It is not possible to establish data call connections from your PC DOS prompt. The data telephone is connected to the PC 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. 4 Strata DK PC/Data Interface 5/99 The Grand Tour Stand-alone Data Interface Unit (PDIU-DS) Connections Stand-alone Data Interface Unit (PDIU-DS) Connections 1234 DNT4 ON Data devices, such as printers, modems, mainframe computers, etc., must be connected to a PDIU-DS with an RS-232 cable and connector.

Personal Computer Dialing of Voice Calls A PC which contains a software package and provides a dialing feature can be used to place outgoing voice calls. Typically, Personal Information Management or Appointment type software packages contain dialing programs. The dialing program must be Hayes modem compatible; however, when using the Toshiba Data Telephone, a modem or special line is not required. Strata DK PC/Data Interface 5/99 27 Features Personal Computer Dialing of Voice Calls 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 Table 4 CO Line Access Codes System CO Line Access DK14 a or a DK16e and DK16 a or a DK40i and DK40 a or a DK424 (RCTUA) a or a DK424 (RCTUBA/BB) a or a DK424 (RCTUC/D) a or a DK424 (RCTUE/F) a or a 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. 28 Strata DK PC/Data Interface 5/99 Mode Definitions 3 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.) Strata DK PC/Data Interface 5/99 29 Mode Definitions Data Communications Mode ♦ 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. 30 Strata DK PC/Data Interface 5/99 Mode Definitions Data Communications Mode 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 SRegisters, 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 ➤ Type ATSX? and press Enter (X is the S-Register you want to check). The value along with the “OK” Result Code is displayed. ➤ To change the value of an S-Register ➤ 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.) 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,, ENTER, etc. All AT commands must be typed as capital letters. Strata DK PC/Data Interface 5/99 31 Mode Definitions Data Communications Mode ● 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. 32 ♦ 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. Strata DK PC/Data Interface 5/99 Mode Definitions Data Communications Mode 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 Table 5 DIU AT Command Set Command Description AT Command prefix ATDY...Y Voice call to telephone number (Y…Y = any number of digits), internal or external ATDDXXXX Data call to DIU station number XXXX (1~4 digits) Enter Carriage return character A Go into the answer mode; attempt to go to Communication Mode A/ Re-execute previous command line; not preceded with AT nor followed by Enter D Go into originate mode; dial number that follows; attempt to go to on-line state Strata DK PC/Data Interface 5/99 33 Mode Definitions Data Communications Mode DIU AT Command Set (continued) Table 5 Command EO Disable character echo in Command Mode E1 Enable character echo in Command Mode H0 Go on-hook (hang up) H1 Go off-hook O Go to Communication Mode Q0 DIU returns Result Codes Q1 DIU does not return Result Codes SR = n Set Register “R” to value “n” (R = 0~12) SR?
