Disclosed are a method for switching a serially linked system (100), particularly a serial data bus system, from subnetwork operation (T) in which at least one node (22, 28) and/or at least one user (32, 38) of the system (100) is/are in a state of reduced energy consumption and is/are not addressed and/or not activated by the signal levels (40, 42, 44) of the data communication in the system (100), to full network operation (G) in which all nodes (20, 22, 24, 26, 28) and/or all users (30, 32, 34, 36, 38) of the system (100) are addressed and/or activated by the signal levels (46, 48) of the data communication in the system (100), and a corresponding system (100). In order to further develop said method and system (100) such that the nodes (22, 28) and/or the users (32, 38) of the network, i.e. on the data bus (10), can be awakened in a simple and effective manner, at least one defined, particularly continuous and/or especially symmetric, signal level pattern (62, 64) is recognized during data communication in the system (100) in order for the system (100) to switch from subnetwork operation (T) to full network operation (G).
