Abstract
The invention relates to synchronization applied to a data stream structured as super-frames. Each block in a super-frame comprises a slow synchronization part and at least one traffic frame. The slow synchronization parts in the super-frame result at least from a decomposition of a synchronization management word. Additional synchronization parts similar to the slow synchronization parts and distributed in place of traffic frame bits in the super-frame are inserted in the super-frame. The invention provides for fast synchronization coexisting with a pre-existing slow synchronization without increasing the bandwidth. The invention is particularly applicable to cryptographic synchronization between fixed and/or mobile terminal equipments operating in interconnected dissimilar networks whose synchronization time constants differ.
