摘　　要：The timeslot synchronous mechanism of the upstream channel in HFC network is introduced in this paper.A mathematical model is built for the fault recovery of HFC network. We emphasize on analyzing the average time ofHFC network completing fault recovery. The result of theory analysis shows network scale of service domain, back-off parameter's value of the contention resolution algorithm and the allocation policv of initialization ranging slot havegreat effect on the fault recovery ability of HFC broadband access network.The timeslot synchronous mechanism of the upstream channel in HFC network is introduced in this paper.
