ABSTRACT:
A self-routing exchange which includes switch modules connected in multiple stages. A synchronous transfer mode (STM) circuit switch module, which is capable of changing over a connection relationship between incoming highways and outgoing highways, is provided between the multistage-connected switch modules and self-routing switch modules. Asynchronous transfer mode (ATM) switch modules are provided as switch modules in preceding and succeeding stages of the circuit switching module. In dependence upon the number m of self-routing switch modules, a controller sets, by means of software, the connection relationship between the incoming and outgoing highways in each of space switches incorporated within the circuit switching module. As a result, the total mn-number of incoming highways from the self-routing switch modules are connected to respective ones of mn-number of outgoing highways set by the controller. In a case where self-routing switch modules are added on later to expand the system, the controller changes the connection relationship between the incoming and outgoing highways in each space switch within the circuit switching module, using software.
