发明名称 Teleprinter private branch exchange
摘要 In a teleprinter private branch exchange having a communications unit, to which teleprinter terminals are connected, a central unit and a storage unit, the load due to connections between the individual units on a bus connecting the individual units together is kept as low as possible. For this purpose, the individual units are connected to the bus through the processing systems such that the processing unit of the central unit controls the connection of the processing units of the other two units using the bus for just one signal transmission. It is also provided that the processing unit of the central unit also triggers the execution of the procedures to be executed in the communications unit and supplies the addresses of those storage areas in the storage unit in which associated signals are to be stored or are stored.
