TAPI
NOTE:
See the documentation that came with the TAPI-compliant card for more information
on using TAPI devices and to verify that the card works with your computer.
Your computer supports TAPI-compliant modem cards using the standard TAPI connector
(the green connector labeled MODEM or TELEPHONY). If your modem supports voice
features, you can connect your modem to the TAPI connector and then use your audio
speakers and microphone as an answering machine or 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 audio files over the telephone by using third-party software.
CAUTION: Before you begin any of the procedures in this section, follow the
safety instructions in the
System Information Guide
.
CAUTION: To guard against electrical shock, always unplug your computer from
the electrical outlet before opening the cover.
