Abstract: In a data processing equipment handling communication lines connected to a central control unit through adapters and a CCU input/output bus, an error reporting device is provided in each adapter for reporting error conditions occurring in the adapter to the central control unit. The adapters are of the type including a microcode controlled microprocessor provided with input and output buses connected to the CCU input/output bus through an interface. The error reporting device in association with dedicated circuits in the interface insures the transmission of the error conditions occurring in the adapter to the central control unit, even when such error conditions affect the integrity of the microcode. When the error reporting device detects an error affecting the microcode integrity, it generates a hard stop signal which causes the operation of the microprocessor under the control of the microcode to be stopped and the error conditions to be transferred to the central control unit making use of the same paths as those used for reporting errors which do not affect the microcode integrity.

Abstract: A DEVICE FOR REPORTING ERROR CONDITIONS OCCURRING IN ADAPTERS TO THE DATA PROCESSING EQUIPMENT CENTRAL CONTROL UNIT In data processing equipment handling communication lines connected to a central control unit (CCU) through adapters and a CCU input/output bus, an error reporting device is provided in each adapter for reporting error conditions occuring in the adapter to the central control unit. The adapters are of the type including a microcode controlled microprocessor provided with input and output buses connected to the CCU input/output bus through an interface. The error reporting device in association with dedicated circuits in the interface insures the transmission of the error conditions occuring in the adapter to the central control unit, even when such error conditions affect the integrity of the microcode. When the error reporting device detects an error affecting the microcode integrity, it generates a hard stop signal which causes the operation of the microprocessor under the control of the microcode to be stopped and the error conditions to be transferred to the central control unit making use of the same paths as those used fro reporting errors which do not affecte the microcode integrity.

Abstract: METHOD AND DEVICE FOR EXCHANGING INFORMATION BETWEEN TERMINALS AND A CENTRAL CONTROL UNIT An information exchange method in a communications controller comprises a central control unit associated with a store that provides a number of parameter/status and data areas equal to the maximum number of interfaces to be managed by the controller. The store contains a line vector table which indicates the address of each area assigned to each interface. The exchange of the parameter/status information and data on the input/output bus uses a minimum number of input/output operations controlled by the program stored in the store.
