Patent ID: 7194007

Claim:
A method of data communication over a first time division multiplexed bus, including one or more digital signal lines, said method comprising: determining whether an incoming call is a voice call or a data call; receiving an analog data signal over a voiceband of a telephone line from a first analog modem for said data call; utilizing a linear coding process to generate a plurality of digitized analog data signal samples from said analog data signal; transmitting said plurality of digitized analog data signal samples via said one or more digital signal lines of said first time division multiplexed bus to a second analog modem; demodulating said plurality of digitized analog data signal samples by said second analog modem to generate digital data; transmitting said digital data by said second analog modem over one or more digital signal lines of a second time division multiplexed bus; utilizing a non-linear coding process to generate a plurality of digitized analog voice signal samples from an analog voice signal received over said voiceband of said telephone line for said voice call; and transmitting said plurality of digitized analog voice signal samples via one or more digital signal lines of a third time division multiplexed bus.
