Basic Telco System
A basic telco block diagram is illustrated at
the right.
The output of the phone hybrid is brought to
a console line level analog input. That fader
channel is assigned as a Phone channel so that it
will configure the console mix minus and other
phone functions automatically.
The mix minus output of the console is con-
nected to the telephone hybrid input. The mix
minus has all of the console audio MINUS the
caller's voice so that there is not any feedback.
The console Telco channel logic can be used
to pick up or disconnect the phone line auto -
matically as the channel is turned on and off.
If it desirable to record the caller, the "Assign-
able Audio Output" (assignable as a cue or
record output) may be set up as a record output.
In that case it is connected to an audio recorder
as shown.
