A group switching apparatus for multi-channel data is disclosed. It includes a speech memory to temporarily store a time slot to be switched, and a connection memory (CM) to store group connection information. Also, it includes a processor matching unit to interface group connection information provided from an upper processor to the CM and a counter to count a system clock signal and output a read address for the CM. Additionally, an offset generating unit receives group connection information outputted from the CM and generates a first offset value according to a signal representing an 'ON' state of group connection, and an adder adds the output of the counter and the output of the offset generating unit and outputting the added value as a read address for the SM.
