TAPI
The TAPI features of your computer enable Microsoft
®
Windows
®
-based
applications to operate with a wide variety of telephony devices, including
voice, data, fax, video, and so forth. TAPI applications require a TAPI service
provider (TSP), which is a software driver that allows TAPI applications to
communicate with different types of TAPI hardware.
Microsoft Windows provide a TSP called Unimodem, which is a "universal"
modem service provider that supports a wide range of commonly used
modems. For more information on Unimodem, see your Windows
documentation. When using a TAPI device other than a modem, such as a
PBX or a voice processing card, you will need a TSP provided by the
manufacturer of the device.
The TAPI system-board connector uses a 4-pin cable to interface your
internal TAPI-compliant expansion card with the audio system in your
computer. To locate the TAPI system-board connector, see "
System Board
Components " or the interior service label. Your computer supports TAPI-
compliant cards using the standard TAPI connector. For example, you can
connect your modem to the TAPI connector and then use your audio
speakers and microphone as a speakerphone. The microphone carries your
voice into the computer and then through the TAPI system board connector
to your modem card. The caller’s voice enters through the modem card to
the TAPI system board connector and then out to the speakers. You can also
use this configuration to record and play sound files over the phone.

System Board
Components " or the interior service label.
