    • The present invention aims at providing an ascending transmission speed controlling method and a communication system in an ATM-PON (asynchronous transfer mode-passive optical network), in which ascending transmission speeds on the PON are dynamically allocated corresponding to actual transmission states of communication channels of a best effort type, to thereby effectively utilize respective bands. To this end, according to the present invention, in an OLT (optical line termination) constituting the ATM-PON system, active/inactive states of communication channels are identified based on receiving states of ascending data cells transmitted from ONU's of subscriber side, respectively, and a congestion state of the ATM network is recognized by extracting B-RM (backward resource management) cells from descending data cells, respectively, transmitted from the ATM network, so that ascending transmission speeds on the PON are allocated to communication channels corresponding to service categories, based on such as the thus recognized information.
