TAD
TAD is a connector for telephony
audio devices such as voice modem
cards. By installing a PCI voice
modem card that is also equipped
with a TAD connector, connect one
end of the cable (that came with
the card) to the card’s TAD
connector and the other end to the
TAD connector on the system
board. The voice modem will
interface with the onboard audio
allowing voice to come from the
external speaker.
