ABSTRACT:
A media gateway system and a method of substituting one unit for another in the system. The system uses cross point switches that are controlled by a main control unit. When a voice processing unit or a circuit interface unit or a packet interface unit malfunctions and another unit takes over the function of the malfunctioning unit, only the cross point switch setups need to be modified and not the settings in the TDM switch or the packet switch.
