FIELD: radio engineering. SUBSTANCE: device generating messages for commutation system has principal processor that controls output of speech messages for all channels of speech servicing, two-port storage with unspecified selection of data of address of retrieval of speech signal for storage, central processor responding to interruption signal for recording of data of address of retrieval of speech signal in two-port storage with unspecified selection and output of data on condition of output of speech signal, common storage for transmission of data of command for output of speech signal from principal processor to central processor and for transmission of data on condition of output of speech signal from central processor to principal one, storage of fixed speech signal to store data of fixed speech messages, storage of edited speech signal for storage of edited speech messages and unit controlling storage and processing of speech signal for feed of interruption signal to central processor, for reading of data on address of output of speech to central from two-port storage with unspecified selection, for feed of read data in address of output of speech signal to storage of fixed speech signal, to storage of edited speech signal, for conversion of parallel data of signal of speech message obtained from storage of fixed speech signal or from storage of edited speech signal into series data and for transmission of series converted data over subroute into device of time commutation of commutation system. EFFECT: improved functional reliability of device. 7 cl, 4 dwg, 1 tbl
