ABSTRACT:
A circuit switching apparatus and method for time division network with various transmission speeds for time-division multiplexing a plurality of circuits including signals at different transmission speeds, transmitting the same onto an input highway, repeatedly recording the transmitted signals in a data memory in a predetermined order, reading respective recorded signals in a predetermined order onto an output highway. An access unit for reading signals from the data memory has an address control memory for storing circuit switching information, a circuit speed control memory for storing transmission speed information for the respective circuits and an address generating section for generating an address for accessing the data memory on the basis of the circuit switching information and the circuit transmission speed information from those memories.
