<p>A method of detecting or anticipating synchronisation faults provided for a digital telecommunications network (1) having a plurality of nodes, each of which obtains a synchronisation signal from a source comprising a selected one of the other nodes. The network is interrogated to obtain data on its topology and, for each node, the identity of the selected respective other node. This information is used to construct a virtual model (12) of the network, and the model is then inspected if any node of the system is to select an alternative synchronisation source. Since the data on the topology of the network and the configuration of all the other nodes have already been obtained, this analysis can be relatively rapidly performed, so that any synchronisation feedback loops in the network can be anticipated before they actually occur.</p> |
