Abstract

PURPOSE:To collect detailed information on failures of monitored stations, by providing bits for detailed monitor control information in a plurality of monitor control bits in a data frame. CONSTITUTION:A monitor control station (hereinafter called a SV station) makes transfer instruction of detailed data to monitored stations (hereinafter called node stations), by using several frames to several tens of frames of a transfer bit 21 shown in Fig. A. Each node station makes transfer to the next station with a transmission/reception switching section 7 if the instruction data from the said SV station is not destined for the station itself. On the other hand, when the instruction data from the said SV station is destined for the station itself, a station control section 16 returns ruquired data corresponding to the instruction to the SV station. Thus, detailed monitor control information can be transmitted from the node stations to the SV station with the instruction from the SV station separately from polling monitor control information by using several frames to several tens of frames of transfer bit 21 in Fig. A.
