The function Audio Monitoring provides several possibilities to monitor all
available Audio signals.
FIG. 18 AUDIO MONITORING
Mode PRETALK
After the function Monitor Pretalk (Receive & Transmit) on AUDIO OUT
1/2 is activated the PreTalk (caller is in PRETALK) is displayed on the Au-
dio interfaces Audio Out 1 respectively Audio Out 2. The received signal
and the transmitting signal are mixed and provided as Audio composite
signal.
Mode ON AIR
The function Monitor Caller on Handset/Headset enables a monitoring
of the caller signal via the Handset Audio interface if the caller has been
switched ON AIR.
If there is one caller ON AIR and a second caller in PRETALK only the nor-
mal PRETALK function is active.
A monitoring of the Audio signal via the Audio In 1 respectively the Audio
In 2 interface on the Handset Audio interface is possible by activating the
function Monitor AUDIO IN 1/2 on Handset/Headset , if a caller has been
switched ON AIR.
If both options are activated, a composite audio signal is generated.
