PURPOSE: To not only simultaneously transmit a congestion report to terminals but also avoid recongestion after congestion release by providing logical independent lines between a host and plural terminals in the logical 1:n communication between the host and plural terminals. CONSTITUTION: For the purpose of simplifying the congestion report, logical independent lines 4 are provided between a host equipment 1 and plural terminal equipments 21 to 2n besides signal lines 3, and a mechanism to make the congestion report in the general broadcasting system is provided to report the congestion. The congestion report is not transmitted to signal lines 3 together with data but is transmitted by logical independent lines 4 independently of data. In the recongestion avoiding method, the independent line 4 of the host equipment 1 is provided with a congestion counter 7 which counts the number of data and transmits it to the terminal side, and the independent line 4 on the terminal equipment side is provided with a congestion register 8 which receives the number of data transmitted from the congestion counter on the host equipment side. The count or the congestion counter 7 is reduced after congestion release and is gradually increased, and thereby, the terminal equipment side receives the count by the congestion counter a to control the data to the host side.
