12.2.3. Using a telephone hybrid to
transfer audio
By connecting an external telephone hybrid to the Courier, audio can be played
from the Courier down a telephone line and it can also receive a return feed from
the telephone line, to monitor. The Courier can generate DTMF dialling tones to
dial requested numbers.
Connect the audio output of the telephone hybrid to the right audio input of the
Courier and connect the left audio output of the Courier to the audio input of the
telephone hybrid. Connect the telephone hybrid to the telephone line.
Note : The inputs that are used on the Courier are important because in this
mode the left input takes the input that is transmitted to the telephone line
whereas the right input is used for monitoring from the telephone line.
Connect a microphone to the left analogue input of the Courier ensuring that the
MIC/LINE switch is set to MIC for the left input and LINE for the right input.
To operate with an external telephone hybrid, you need to make the following
selections :

choose [Connectivity], [Live Connect] and [Select Phone #] :

Courier will show the following screen whilst dialling the number :
