Installing Computer Telephony Integration
This chapter gives you information about installing Toshiba's Computer Telephony
Integration, (CTI), software. Currently, it includes procedures for using a Personal Computer
Interface Unit (PCIU) for Telephony Application Programming Interface (TAPI) running
under both Microsoft Windows, NT, Windows 3.1 and Windows 3.11 for Workgroups.

About Strata DK and TAPI

The Telephony Specification was jointly developed and copyrighted by Intel and Microsoft.
It consists of both TAPI, used by applications, and the Telephony Service Provider interface
(TSPI), implemented by manufacturer of the Telecommunications terminal/system.
Toshiba provides the TAPI connection through a Strata DKT2000-series telephone with a
modified data Interface Unit. The Personal Computer Interface unit (PCIU) for TAPI
integrates into the bottom base of a 2000-series telephone. Installation instructions for the
hardware are contained in the Strata DK280 1&M (July 1996), Manual Chapter 6 paragraph
9.
Windows Telephony is a component of Windows Open Services Architecture. This
architecture provides telephony services when connected to many different telephone
switches. Therefore, an application needs to know only the definition of the API
(Application Program Interface) and not its implementation.
The Strata DK TAPI Service Provider (DK TSPI) comes with each PCIU. This device, along
with this software module, allows a Windows-based PC to interconnect with the phone
system for receiving and making calls. Any TAPI-compliant PC software becomes
compatible with Strata DK systems. Toshiba's TSPI is configured using the Telephony icon
installed as part of TAPI in the Microsoft Windows Control Panel.
The disk set also contains a "middleware" software known as StrataLink. This application
enables other Windows-based software to also work with Strata DK systems. This is
achieved by using another standardised mechanism called "DDE", (Dynamic Data
Exchange). StrataLink is further explained in Section 3 called "Using StrataLink for CTI
Connections".
