PURPOSE: To decrease the number of the signal lines by adding part of the information stored in the register of the storage program control type to the internal device designation window circuit and carrying out the identification for the command via the output of the window circuit and internal device.
CONSTITUTION: The command given from control processor CC of the storage program control exchange is stored in SRD register 3 of signal reception/distribution device SRD. This stored information is applied to internal device number decision circuit 7 by the signal to timing circuit 4 which produces various types of control timing based on the synchronous bit information of processor CC and applied also to internal parity check circiut 5. After confirmation of the normalcy of the reception signal, the number codes of internal devices 1n∼11 are transmitted to drive these internal devices. Then the normal operation confirming signals sent from devices 1n∼11 plus the output gate sent from internal device designation window circuit 21 which supplies the internal device number sent from register 3 are secured at repeating circuit 22, which is informed to processor CC.
