<p>The invention relates to a method for synchronizing interconnected SDH and PDH telecommunications networks (31, 32). In order to find the master node of the interconnected network with the greatest possible certainty also in failure conditions, a signal to be transmitted to a PDH network is provided in a device (33) of a SDH network (31) connected to the PDH network with at least one status bit (1cb, mcb) known per se for LP synchronization in such a way that said at least one status bit is interpretable in the PDH network by using rules of interpretation known per se.</p> |
