Using the Modem’s Voice Features
This modem supports TIA IS-101 commands applicable to a Telephone Answer-
ing Device. In order to take advantage of this feature, you will need a Sound
Blaster ® compatible sound card equipped with an external microphone and exter-
nal speakers. A software application; such as the one supplied with the modem;
which supports these TAD functions is also required.
A modem based Telephone Answering Machine works by using a sound card
equipped with a microphone to record an outgoing message. This message is stored
as a .wav file which is transferred to the modem by the application program when
an incoming call is detected. The modem’s internal electronics converts the digi-
tal information contained in the .wav file into an audio signal which is then sent
over the phone line. The person calling hears your outgoing message and responds
with an incoming message.
The sequence of recording an incoming message is the reverse of an outgoing
message. The modem’s internal electronics converts the audio signal into a digital
format and sends it to the application program. The application program then
formats and stores the incoming message as a .wav file. When you play back your
stored messages by selecting them from within the application program, they are
sent to the sound card. You then hear your recorded messages through the sound
card’s speakers.
The process is simple in concept but it’s success is totally dependant on the appli-
cation program and it’s ability to communicate with both the sound card and the
modem. If you wish to use your modem as a Telephone Answering Machine, please
try the software witch came with your modem. It’s default parameters have been
specially configured to identify and use your modems voice capabilities. Even if
you have decided to use another third-party application, try your included appli-
cation first. This will allow you to test the modem and it’s voice functions before
investing in an expensive retail software package. You may find that the supplied
software performs just as well as an aftermarket software package.
