Abstract

A combined audio and modem interface unit includes a standard audio component and an audio/modem signal processing unit. The audio component has two internal input and two internal output channels and is selectably connectable to at least an audio left port, an audio right port and a telephone port. The signal processing unit separately processes the modem and audio signals received from the audio component. The modem and one stereo audio signal can also be modulated and sent on a single output channel.
