Versatile telephone transmission circuit
with dialler interface
Curve (1) is valid when the receiving amplifier is not driven or when MUTE = HIGH. Curve (2) is valid when MUTE = LOW and the receiving amplifier
is driven; V
The supply possibilities can be increased simply by setting the voltage drop over the circuit V
between REG and SLPE.
(1) May be connected to decrease the terminating impedance.
