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.
