| 摘要 |
The invention relates to a method and an arrangement for synchronizing two or more individual communication networks (B1-B6) of the time multiplex type, in order to form a composite network thereof, said individual networks having nodes (N1-N5), by means of which cyclic transmission of time frames is performed, which include time slots intended for the data transmission. One node in the composite network is assigned the role as a superior master node (N1) determining the transmission speed of the individual communication networks. This is obtained by adding a fixed idle pattern to each time frame sent out from the superior master node, followed by a fixed triggering pattern as a start of the next time frame. At the receipt of the triggering pattern in a master node (N2-N5) in an individual communication network, which synchronizes the data transmission of this communication network, this master node starts sending a new time frame. <IMAGE> |
