ABSTRACT:
A switching multi-mode modem that switches on the four wire side of the DAA where the two-wire side of the DAA is connected to a land based telephone network. The modem includes a DAA, a first DSP capable of performing all modem digital signal processing functions and a second DSP capable of performing conversion and compression of analog voice signals to digital signals. The modem includes a headset connector and a cellular telephone connector and a switching network connected between the first DSP, the second DSP, the four-wire side of the DAA, the cellular telephone connector and the headset connector. The modem further contains a microcontroller which is connected to the first DSP and the second DSP and the switching network and separates audio signals from data signals and causes the switching network to switch into states that configure the modem to operate in one of the following states: Radish voice mode, or a Radish data mode, or a cellular telephone mode, or a business/audio mode or a digital simultaneous voice and data mode upon command from said microcontroller.
