An amplifier circuit for amplifying a downstream signal carrying voice
over internet protocol data is disclosed. The amplifier circuit includes
an input which receives the downstream signal, an amplifier, an output,
and a bypass circuit. The amplifier receives the downstream signal from
the input and amplifies the downstream signal. The amplifier then outputs
an amplified signal carrying voice over internet protocol data. The
output receives the amplified signal from the amplifier and is connected
with an external device capable of receiving and converting voice over
internet protocol data to sound. The bypass circuit connects the input
directly to the output. Upon activation of the bypass circuit, the
downstream signal is transmitted directly from the input to the output
and bypasses the amplifier.
