The present invention relates to a broadband terminal equipment for congestion control in the ring structure and its control method, and the object of the invention is to prevent ATM traffic congestion which can be produced in the ring in order to realize the ATM subscriber premises network having a ring structure. The invention is provided with a means (313) which stores real time traffic for a while, a means (314) which stores non-real time traffic for a while, a means (312) which notifies a broadband network terminator of network congestion and controls network traffic transmission, an ATM adaptation layer transmission means (317) inclusive of a means (315) which stores self-created real time traffic and a means (316) which stores self-created non-real time traffic, and a means (319) which transmits the self-created real time traffic and non-real time traffic and receives real time traffic and non-real time traffic which are inputted from a front broadband terminal equipment if destined for itself and transmits those traffics to a rear broadband terminal equipment if not destined for itself. The invention is used in the broadband integrated service network subscriber premises equipment.
