Abstract
A data transmission among the exchange modules in the building block type exchanger with improved efficiency, reliability and simplicity of implementation. An ATM connector is connected to the STM exchange module connector through at least one STM transmission line containing logical transmission paths provided in correspondence to the logical STM transmission path for transmission of specific data connected from each exchange module to the STM exchange module connector and fixedly switched by the STM exchange module connector to the logical transmission paths of the STM transmission line connected to the ATM connector. The specific data to be transmitted from each exchange module are transmitted in a form of ATM cells to the ATM connector, while all the specific data to be transmitted to each exchange module are multiplexed in a form of multiplexed ATM cells at the ATM connector and the multiplexed ATM cells are transmitted from the ATM connector to each exchange module.
