Abstract

A device for adjusting a modulating scheme of a communication system having a modem. The device comprises a modulation overlay, capable of demodulating and modulating analog signals to respectively provide demodulated incoming analog signals and modulated outgoing analog signals. The demodulated incoming analog signals are recognizable by the modem.
