摘要
A method is intended for distributing a frequency reference to network clocks (NC1-NC5), comprising a synchronization card (SC) and an interface card (IC), and belonging to a mobile network (MN) having a physical-layer-based protocol for distributing the frequency reference to the network clocks according to a chosen topology, and a packet-based protocol for distributing this frequency reference to the network clocks respecting this chosen topology. This method comprises a step (i) during which one detects a synchronization failure in a synchronization card (SC) of a failed network clock (NC2) connected to neighbour network clocks (NC1,NC3-NC5), a step (ii) during which one activates a mechanism of the packet-based protocol between a master neighbour network clock (NC1) and slave neighbour network clocks (NC3-NC5), and a step (iii) during which one uses the activated protocol to transmit the frequency reference recovered by the master (NC1) to the slaves (NC3-NC5) by following the topology.
