A switching method, switching equipment and a switching network are provided by each of which the data is transferred economically and with small transfer delay and the unit to which the data is to be transferred is selected every channel. In AAL type apparatuses, CPS packets a, b, c and d in which the voice data signals are encoded and the like are processed with an AAL type 2 to be multiplexed in ATM cells. The ATM cells in which the CPS packets are multiplexed are inputted to switching equipment. By a voice data decode unit within the switching equipment, for example, the CPS packets a and b are decoded into PCM codes a' and b', respectively. ATM cells of an ATM type 1 in which the CPS packets a', b', y' and z' are multiplexed are generated by a channel switching unit within a network to be suitably inputted to AAL type 1 apparatuses. |
