Abstract:
1. A communication system in which said communication system is a first communication network having a first master station apparatus, a plurality of first slave station apparatuses, a transmission path for connecting said master station and said plurality of slave stations, and a managing apparatus for making management control of the first communication network and a passive optical network in which said managing apparatus communicates a first control signal and a monitor signal with said first master station apparatus and each of said plurality of first slave stations by a first communication protocol, and monitors and controls said first master station apparatus and each of said plurality of first slave stations, thereby transmitting and receiving signals between an uplink communication network connected to said first master station apparatus and a terminal connected to each of said plurality of first slave stations, comprising: the passive optical network which is constructed by a second master station apparatus, a plurality of second slave station apparatuses, and an optical transmitting path for connecting said master station and said plurality of slave stations and in which said second master station apparatus and each of said plurality of second slave stations communicate a second control signal and a monitor signal by using a second communication protocol and monitor and control said second master station and said plurality of slave stations, thereby transmitting and receiving signals between said uplink communication network connected to said second master station apparatus and a terminal connected to each of said plurality of second slave stations, wherein said second master station has an interface for transmitting and receiving said first communication protocol to/from said managing apparatus, a processing unit for processing said first communication protocol, said first control signal, and said monitor signal, and a converting unit for converting said first communication protocol, said first control signal, and said monitor signal into said second communication protocol, said second control signal, and said monitor signal on the basis of an output of said processing unit, and said managing apparatus and said second master station of said passive optical network are connected and said managing apparatus transmits and receives said first control signal and said monitor signal to/from said second master station by said first communication protocol, thereby executing the transmission and reception of the signals between said uplink communication network and said terminal through said passive optical network.
