SYNCHRONISATION SYSTEM OF A DIGITAL PACKET MULTIPLEX |
摘要 |
A digital train is synchronized to correct the framing of received information. To this end, the transmitted digital train is timely structured into recurrent time intervals having a fixed length. The information to be transmitted is divided into blocks called packets, having the length of a time interval and comprising a field of data and a header used for identifying the packets. A digital transmission system with a TDM multiplex is divided into equal and recurrent time intervals, wherein the information is indexed by an associated explicit header, and wherein the absence of information in a time interval is indexed by a specific header which is not used elsewhere as a header. The recognition of a specific address is also used for synchronizing the alignment of the time intervals. |
