Abstract
PURPOSE:To diagnose a line interface control part during a system is operated by supervising an interface signal line between a line adapter and a MODEM with a diagnosis control part provided in a MODEM by the CRC check of data from the line adapter or a parity check. CONSTITUTION:A diagnosis control part 31, which is provided in a MODEM 30 and has, for example, a CRC check function, a parity check function and a signal line supervising function, executes the diagnosis of an interface 10 between the respective MODEMs 30 and a line adapter 1. This diagnosis is informed an abnormal information editing device 40 and the line number of the line in which the abnormality is generated and the type of the abnormality are informed a service processor interface adapter 12. Thus, the transmitting function of the respective line adapters is supervised during communication and the abnormality of a communication control device line interface control part 11 can be detected.
