Strata DK PC/Data Interface 5/00 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.

Hardware Requirements
2Strata DK PC/Data Interface 5/00
Hardware Requirements
The following hardware is required to originate a data call:
♦A RPCI-DI (replaces digital telephone base)
♦A PC or ASCII Terminal
♦A Toshiba Digital Telephones
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 RPCI-
DI. See Figure 1.
Note Throughout this guide, RPCI-DI-equipped digital telephones that are
connected to ASCII terminals or PCs are referred to as data telephones.
