Abstract (en)
[origin: WO2012001114A1] The embodiments of the present invention relate to a method for time distribution between a first and a second synchronous Ethernet (SyncE) domain, said first and second domains being connected by a third synchronous optical networking/synchronous digital hierarchy (SDH-SONET) domain in which a reference parameter associated with the time is distributed through the synchronous Ethernet (SyncE) domains by at least one additional type length value (TLV) field of a Ethernet synchronization messaging channel (ESMC) message, and a reference parameter associated with the corresponding time is distributed through the synchronous optical networking/synchronous digital hierarchy (SDH-SONET) domain by at least one additional type length value (TLV) field at a message of the IEEE 1588 V2 protocol.
