Abstract
An input data (input frame) is sequentially stored in memory in time slot units. A counter counts the number of input pulses of a clock synchronous with the time slot of the input frame, outputs the count value as a write address to the memory, and outputs it as a read address to the memory. A processor in a cross-connection device preliminarily writes to the memory data indicating switching information of a time slot. The memory outputs the data stored at an address input from the counter as a read address to the memory. The memory outputs data of a time slot of an input frame stored at the address as time slot data of an output frame.
