Abstract:
A group switching apparatus for multiple-channel data, comprising:a speech memory (SM) coupled to temporarily store at least one time slot to be switched; a connection memory (CM) coupled to store single connection information; a group connection memory (GCM) coupled to store group connection information; a counter coupled to count a system clock signal and output a read address to the CM; an address generator configured to convert an output of the counter and generate a read address for the GCM; a processor matching unit configured to provide interfacing connection information received from an upper processor to one of the CM and GCM; a multiplexer coupled to selectively output an output of the CM or an output of the GCM according to a connection state signal outputted from the GCM; and an adder coupled to add an output of the counter and the output of the multiplexer, and output an added value as a read address for the SM.
