Patent ID: 7991017

Claim:
A method for controlling a communication system for communicating audio data between each of a plurality of terminal units of said communication system, wherein the method comprises the steps of: buffering audio data by a plurality of terminal units; transmitting control signals to said terminal units through a master bus; transmitting audio data from said terminal units through a data bus; requesting by a central unit said audio data from said plurality of terminal units via said master bus and receiving audio data through said data bus; examining an identity of said terminal units by said central unit during an initialization phase; transmitting a predetermined data frame including a first synchronization signal, a terminal unit address of a respective terminal unit, a payload field and a second synchronization signal by said central unit via said master bus during a configuration phase; and transmitting audio data through said data bus by one of said plurality of terminal units within an audio sample time interval that corresponds to the interval between said first synchronization signal and said second synchronization signal.
