PROBLEM TO BE SOLVED: To provide the bulk communication method and the bulk communication equipment by which bulk communication is attained even in the case that a delay cannot be corrected due to a defect at a receiver side. SOLUTION: In the case that reception delay buffers 114, 115 at a reception station side cannot correct a delay between two B channels in the bulk communication utilizing 2 sets of B channels B1, B2, a delay difference detected by reception delay difference detection sections 110, 111 is sent to a transmission station side. Delay correction buffers 104, 105 conduct delay correction in advance so as to eliminate the delay difference between the channels when transmission data reaches the reception station side based on the received delay difference and the transmission station transmits the transmission data whose delay is corrected as above to the reception station side.
