MONITOR SYSTEM FOR MCA CONTROL STATION

摘要

PURPOSE:To supervise plural control stations with a single supervisory equipment by transmitting and receiving the information on the state change among MCA control stations and transmitting the information on the state of each MCA control station via this station itself by means of each slot. CONSTITUTION:Each MCA(multi-channel-access) control station 10 transmits the external output in case a supervising item has its state change. Then the external output is sent in common to the state change slot inputs of each station 10 and the corresponding slot is set at '1' or '0'. This state change slot is sent to a supervisory station 20 through a control channel. The station 20 can judges the station 10 having a state change via said slot regardless of the control channel kept in a supervising state. Thus it is possible to quickly acquire the information on plural control stations with a single supervisory equipment.
