The Grand Tour
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.
